Performance\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eSoudaseal 205FT performs as a flexible, high tack adhesive sealant by combining strong early grab with durable elastic curing. The high initial tack is genuinely beneficial during installation, helping to hold materials in place shortly after application and reducing the reliance on clamps, props or temporary support in many suitable applications. This is particularly useful when fixing panels, profiles, trims or boards, where slipping or movement during the early stages of curing can affect alignment and finish quality.\u003c\/p\u003e\n\u003cp\u003eThe moisture curing system gives the product a skin formation time of approximately 20 minutes and a curing speed of approximately 3mm per 24 hours, depending on bead size, substrate type, temperature and humidity. This provides a workable open time for positioning materials, whilst still allowing the adhesive to cure into a strong, elastic bond. The density of approximately 1.68 g\/ml reflects a stable, substantial paste consistency, helping the product remain in place after application without excessive slump in typical bonding work.\u003c\/p\u003e\n\u003cp\u003eOnce cured, Soudaseal 205FT offers ±20% maximum allowed distortion, an elasticity modulus of approximately 1.30 N\/mm², an elongation at break of more than 200% and a maximum tension of approximately 1.75 N\/mm². These figures clearly demonstrate that the product has been designed to deliver more than simple rigid adhesion. It can stretch, recover and accommodate movement, which is genuinely important in situations where bonded materials may expand, contract, vibrate or move slightly in service. This makes it especially useful for construction applications where long-term flexibility contributes directly to the reliability of the bond.\u003c\/p\u003e\n\u003cp\u003eThe cured hardness of 50 ± 5 Shore A gives Soudaseal 205FT a firm yet elastic final state. It is strong enough for many bonding and mounting applications, while still flexible enough to absorb stress without failure. Temperature resistance from -40°C to +90°C supports use across typical indoor and outdoor service conditions, making it well suited to buildings, workshops, maintenance areas and exposed construction details. Combined with its isocyanate-free, virtually odourless formulation and compatibility with water-based paint systems, Soudaseal 205FT provides a practical balance of strength, flexibility, workability and user-friendly application that is hard to match in everyday construction bonding work.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cstyle\u003e\n  .pc-soudaseal-205ft-table-wrap {\n

Always read the product packaging label and the Safety Data Sheet before application, particularly where the product is being used in confined spaces, occupied properties, commercial fit-out areas or larger construction projects. Suitable gloves should be worn to reduce skin contact, and eye protection is recommended when cutting cartridges, tooling joints, working overhead or applying the product in awkward positions. Although Soudaseal 205FT is virtually odourless and does not contain isocyanates, the working area should still be kept well ventilated during application and throughout the curing period.\u003c\/p\u003e\n\u003cp\u003eAvoid unnecessary contact with uncured adhesive sealant and clean any accidental contamination promptly before curing begins. Do not eat, drink or smoke while handling the product, and wash hands thoroughly after use. Where Soudaseal 205FT is used internally, particularly in smaller rooms or enclosed spaces, continue ventilation until the adhesive has cured sufficiently. Good ventilation helps support moisture curing and improves working conditions for both the installer and surrounding occupants.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSubstrate Suitability\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eSoudaseal 205FT is well suited to bonding and sealing many common construction materials where a high tack, flexible hybrid polymer adhesive sealant is required. It has good adhesion to all usual building substrates and is suitable for compatible surfaces such as lacquered wood, AlCuMg1, AlMg3, stainless steel, electrolytic galvanised steel, steel, steel ST1403, hot dip galvanised steel, polycarbonate, polyamide, fibreglass reinforced epoxy and polyester. It has been designed for both porous and non-porous materials and is particularly useful for bonding objects, panels, boards, MDF, chipboard, profiles and other building components where flexibility, high initial grab and durable adhesion are all required.\u003c\/p\u003e\n\u003cp\u003eHowever, Soudaseal 205FT is not suitable for every surface. It has poor adhesion to PE, PP, PTFE (Teflon®), bituminous substrates, copper and copper-containing materials such as bronze and brass.

Cut the cartridge nozzle cleanly to the required bead size and apply the adhesive sealant in continuous beads, strips or spots, depending on whether it is being used for bonding, mounting or sealing. The product should be applied evenly and with sufficient contact to the substrate, avoiding trapped air and ensuring the bead is thick enough to allow elastic movement after curing.\u003c\/p\u003e\n\u003cp\u003eFor bonding panels, profiles, boards or objects, apply Soudaseal 205FT to one of the surfaces in vertical beads, dots or strips, depending on the size and weight of the item. Always apply adhesive close to the edges and corners of panels to prevent lifting or drumming. Press the materials together before skin formation occurs, adjust as needed and apply firm pressure to ensure full contact. The high initial tack can reduce the need for temporary support in many applications, but heavy items, overhead work, stressed bonds or poorly supported substrates may still require mechanical support until the adhesive has cured sufficiently.\u003c\/p\u003e\n\u003cp\u003eFor sealing applications, apply the product evenly into the joint without air inclusions. Tool the joint before skin formation using a suitable finishing tool. Avoid smudging the sealant onto adjacent materials, particularly visible surfaces, porous materials and finished panels. Masking tape can be used along joint edges where a neat line is required, and it should always be removed before the sealant skins. Soudaseal 205FT is a flexible adhesive sealant, but it should not be used where a specialist glazing sealant, aquarium sealant, natural stone sealant, bitumen product or EPDM-specific sealant is required.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eJoint Dimensions\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eWhen using Soudaseal 205FT for bonding work, always allow enough adhesive thickness to accommodate movement and surface irregularities.

Skin formation occurs after approximately 20 minutes, although this can vary depending on temperature, humidity, bead size, ventilation and substrate absorbency. The curing speed is approximately 3mm per 24 hours under typical conditions. Thicker beads, low temperatures, poor ventilation and less porous substrates can all slow curing, while warmer and more humid conditions generally accelerate it.\u003c\/p\u003e\n\u003cp\u003eThe product should be applied between +5°C and +35°C.

It provides high initial tack, strong final bond strength and good adhesion on slightly damp surfaces, making it well suited to indoor and outdoor building applications where a durable elastic bond is required. Once cured, it remains permanently elastic, helping absorb movement, vibration and minor substrate stress. It is virtually odourless, does not contain isocyanates and can be overpainted with suitable water-based paint systems, making it a practical adhesive sealant for trade, construction, mounting and general bonding work across a wide range of building and maintenance applications.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What materials can Soudaseal 205FT bond to?\u003c\/h3\u003e\n\u003cp\u003eA) Soudaseal 205FT has good adhesion to most common building substrates and is particularly suited to bonding timber-based materials, boards, MDF, chipboard, panels, profiles and plates.

Typical uses include bonding building materials onto porous and non-porous surfaces, mounting panels, plates, boards, MDF and chipboard, fixing timber-based products in joinery and fit-out work, bonding profiles and trims, elastic bonding in vibrating constructions, indoor installation in occupied buildings and commercial premises, outdoor building applications requiring flexible durable bonds, general maintenance bonding and repair tasks, bonding on slightly damp substrates in real site conditions, and general trade and contractor use. Its high initial tack, permanently elastic cure and virtually odourless formula make it practical across a broad range of internal and external construction applications.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) When should Soudaseal 205FT be used instead of a rigid adhesive?\u003c\/h3\u003e\n\u003cp\u003eA) Soudaseal 205FT should be chosen over a rigid adhesive whenever the bonded assembly is expected to experience movement, vibration, thermal expansion or minor substrate stress during service. Because it cures to a permanently elastic state with an elongation at break of more than 200% and an elasticity modulus of approximately 1.30 N\/mm², it can absorb these stresses without cracking or losing adhesion. Rigid adhesives transfer stress directly into the bonded materials, which can lead to failure over time in situations where movement is unavoidable. Soudaseal 205FT is also well suited to bonding dissimilar materials that expand and contract at different rates, and to applications in vibrating constructions where a flexible, durable and elastic adhesive connection is specifically required.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the main advantages of Soudaseal 205FT?\u003c\/h3\u003e\n\u003cp\u003eA) Soudaseal 205FT offers a strong combination of practical advantages for construction bonding and sealing. High initial tack helps hold materials in position during installation, while strong final bond strength and permanent elasticity support long-term performance. Good adhesion on slightly damp surfaces improves practicality on site, and SMX hybrid polymer technology provides weather resistance and durability for both indoor and outdoor use. The virtually odourless, isocyanate-free formulation supports safer use in occupied buildings and enclosed spaces. It is paintable with water-based systems, neutral curing and compatible with many common building substrates. The combination of ±20% movement capability, Shore A hardness of 50 and temperature resistance from -40°C to +90°C makes it a versatile and dependable adhesive sealant.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What technical performance data does Soudaseal 205FT achieve?\u003c\/h3\u003e\n\u003cp\u003eA) Soudaseal 205FT achieves a well-balanced technical performance profile suited to flexible bonding and sealing work. It has a density of approximately 1.68 g\/ml, a skin formation time of approximately 20 minutes and a curing speed of approximately 3mm per 24 hours. Once cured, it offers an elasticity modulus of approximately 1.30 N\/mm², elongation at break of more than 200%, maximum tension of approximately 1.75 N\/mm² and a hardness of 50 ± 5 Shore A. It accommodates movement of ±20% and has a service temperature range from -40°C to +90°C. These figures demonstrate a product designed for durable elastic bonding rather than rigid fixing, capable of absorbing movement and vibration in construction applications over the long term.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How should surfaces be prepared before applying Soudaseal 205FT?\u003c\/h3\u003e\n\u003cp\u003eA) Surfaces must be rigid, clean, dry, stable and free from dust, grease, oil, loose coatings, old adhesive, weak material and any contamination that could affect adhesion. Existing painted or coated surfaces should be checked carefully, as the bond will only be as strong as the coating beneath. Loose, powdery or poorly bonded coatings should be removed back to a sound surface. Non-porous substrates should be cleaned and degreased with \u003ca rel=\"noopener\" href=\"https:\/\/www.platinumchemicals.co.uk\/products\/soudal-cleaner-degreaser\" target=\"_blank\"\u003e\u003cstrong\u003eSoudal Cleaner \u0026amp; Degreaser\u003c\/strong\u003e\u003c\/a\u003e or \u003ca rel=\"noopener\" href=\"https:\/\/www.platinumchemicals.co.uk\/products\/soudal-multi-cleaner-foam\" target=\"_blank\"\u003e\u003cstrong\u003eSoudal Multi Cleaner\u003c\/strong\u003e\u003c\/a\u003e.

For bonding panels, profiles, boards or objects, apply the adhesive to one surface in vertical beads, dots or strips depending on the size and weight of the item. Always apply adhesive close to the edges and corners of panels to prevent lifting or drumming. Press the materials together before skin formation occurs, adjust as needed and apply firm pressure to ensure full contact. The high initial tack can reduce the need for temporary support in many applications, but heavy items, overhead work or stressed assemblies may still require mechanical support until the adhesive has cured sufficiently for the bead thickness and conditions.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How is Soudaseal 205FT applied for sealing joints?\u003c\/h3\u003e\n\u003cp\u003eA) For sealing applications, apply Soudaseal 205FT evenly into the joint without air inclusions, keeping the nozzle matched to the joint size. Tool the joint before skin formation occurs using a suitable finishing tool, working in manageable lengths. Avoid smudging the sealant onto adjacent surfaces, particularly visible finishes and porous materials. Masking tape can be used along joint edges where a neat line is required, and should always be removed before the sealant skins. The minimum joint width is 5mm and the maximum is 30mm, with a minimum joint depth of 5mm. As a general rule, aim for a joint width to depth ratio of 2:1. Use a suitable PE backer rod in deep joints to control depth and prevent three-sided adhesion.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How long does Soudaseal 205FT take to cure?\u003c\/h3\u003e\n\u003cp\u003eA) Soudaseal 205FT cures by reacting with atmospheric moisture. Skin formation occurs after approximately 20 minutes under typical conditions, providing a workable open time for positioning materials before the surface begins to set. The curing speed is approximately 3mm per 24 hours, although this can vary depending on temperature, humidity, bead size, ventilation and substrate absorbency. Thicker beads, low temperatures, poor ventilation and less porous substrates can all slow curing, while warmer and more humid conditions generally accelerate it. The product should be applied between +5°C and +35°C. Once cured, it offers temperature resistance from -40°C to +90°C. Bonded materials should not be put under full load until the adhesive has fully cured for the bead size and conditions.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Soudaseal 205FT be used on damp surfaces?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Soudaseal 205FT has been designed to provide good adhesion on slightly damp surfaces, which is a genuine practical advantage in real site conditions where substrates may not always be perfectly dry. This makes it more usable than products that require completely dry surfaces before application can begin. However, it is important to clarify what slightly damp means in this context. Surfaces should be clean, stable and free from standing water, pooling moisture and surface contamination. The product is not suitable for application over saturated, actively wet or running water surfaces. Where surfaces are visibly wet, they should be allowed to dry to a suitably damp rather than wet condition before Soudaseal 205FT is applied.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Soudaseal 205FT be painted over?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Soudaseal 205FT can be overpainted with suitable water-based paint systems once it has fully cured, allowing bonded or sealed areas to be finished more neatly where appearance and decoration are part of the installation. This makes it particularly useful in interior fitting, refurbishment and decoration work where the adhesive or sealed joint needs to be blended into surrounding surfaces. However, given the wide range of paints and varnishes available, a compatibility test should always be carried out before painting over the cured sealant. It is also worth noting that the drying time of alkyd resin-based paints may increase when applied over the cured product. Checking paint compatibility first avoids finish problems on visible surfaces.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Is Soudaseal 205FT suitable for outdoor use?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Soudaseal 205FT is suitable for both internal and external applications, making it a genuinely versatile adhesive sealant for building work. Once cured, it offers temperature resistance from -40°C to +90°C, helping it cope with the full range of seasonal temperature changes encountered in typical UK and European climates. Its SMX hybrid polymer formulation provides good weather resistance and durability in external building conditions. The permanently elastic cured state allows it to accommodate thermal movement, vibration and minor substrate stress without losing adhesion or cracking over time. However, as with any adhesive sealant, surfaces must be correctly prepared, the correct application temperature range of +5°C to +35°C must be observed, and prolonged extreme UV exposure can cause some degree of discolouration over time.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What does the high initial tack of Soudaseal 205FT mean in practice?\u003c\/h3\u003e\n\u003cp\u003eA) The high initial tack of Soudaseal 205FT means the adhesive provides strong early grab shortly after the materials are pressed together, helping hold many components in position during installation without requiring extended clamping or temporary support in suitable applications. This is particularly useful when mounting panels, trims, profiles or boards, where slipping or movement during the early curing stage can affect alignment, finish quality and working speed. The high initial tack also makes the product more practical for overhead bonding tasks where components need to stay in position while the adhesive begins to develop strength. However, it is important to note that heavy items, stressed assemblies or overhead work may still need mechanical support until the adhesive has fully cured.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the joint dimension requirements when using Soudaseal 205FT for sealing?\u003c\/h3\u003e\n\u003cp\u003eA) When using Soudaseal 205FT for sealing work, correct joint geometry is critical for proper movement accommodation and long-term durability. The minimum joint width is 5mm and the maximum joint width is 30mm, with a minimum joint depth of 5mm. As a general rule for sealing, joint width should be approximately twice the joint depth, supporting elastic movement without overstressing the sealant. Where joints are deep, a suitable PE backer rod should be used to control depth and avoid three-sided adhesion, which restricts movement and increases the risk of joint failure. For bonding work, always maintain an adequate adhesive bed thickness to preserve the elastic properties of the cured material and avoid excessive compression that can reduce long-term performance.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What surfaces is Soudaseal 205FT not suitable for?\u003c\/h3\u003e\n\u003cp\u003eA) Soudaseal 205FT has poor adhesion to PE, PP and PTFE (Teflon®), and should not be used on these low-surface-energy plastics.

It conforms to LEED requirements for Low-Emitting Materials under the adhesives and sealants category, supporting its use in projects where lower VOC content is an important specification requirement. It also conforms to SCAQMD Rule 1168 concerning VOC content for adhesives and sealants, and complies with USGBC LEED 2009 Credit 4.1 for Low-Emitting Materials covering adhesives and sealants VOC content. Together, these credentials make it easier to specify on environmentally focused building and refurbishment projects where product emissions and environmental impact must be considered alongside technical performance. The isocyanate-free formulation also provides additional handling and health considerations compared with some conventional polyurethane bonding systems.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Are there any practical tips for getting the best results with Soudaseal 205FT?\u003c\/h3\u003e\n\u003cp\u003eA) For the best results with Soudaseal 205FT, invest time in thorough surface preparation and always complete a preliminary adhesion and compatibility test on unfamiliar, coated or plastic substrates before full application. Apply the adhesive evenly and ensure good contact across the full bonding area, placing beads close to panel edges and corners to prevent lifting. Press materials together firmly before skin formation begins, which occurs in approximately 20 minutes.

It is considerably easier to remove uncured adhesive sealant than cured material, so cleaning should be carried out as work progresses rather than left until the job is complete. Keep tools, nozzles and work surfaces clean throughout application. Once cured, Soudaseal 205FT can only be removed mechanically, with the aid of \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/soudal-silicone-sealant-remover\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eSoudal Sealant Remover Spray\u003c\/strong\u003e\u003c\/a\u003e where suitable. Mechanical removal may involve cutting, scraping or abrasion, which can damage delicate surfaces. Careful bead application, masking tape use and good housekeeping during installation are the most effective ways to avoid unwanted cured residue.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the limitations of Soudaseal 205FT?\u003c\/h3\u003e\n\u003cp\u003eA) Soudaseal 205FT has several important limitations to be aware of. It is not suitable for PE, PP, PTFE, bituminous substrates, copper or copper-containing materials, natural stone where staining is a concern, structural glazing, aquarium bonding or continuous water immersion. Stress-loaded plastic applications may risk stress cracking. Discolouration may occur through prolonged UV radiation, chemicals, high temperatures or total absence of UV exposure. Contact with bitumen, tar, EPDM, neoprene and butyl can cause discolouration and adhesion loss. Water-based paints are compatible but should be tested before use, as alkyd drying times may be affected. When using different reactive sealants in the same area, the first must be fully hardened before the next is applied. A preliminary adhesion test is essential on all unfamiliar surfaces.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What health and safety precautions should be followed when using Soudaseal 205FT\u003c\/h3\u003e\n\u003cp\u003eA) Before using Soudaseal 205FT, read the packaging label and Safety Data Sheet and follow all stated precautions. Wear suitable gloves to reduce skin contact, and eye protection is recommended when cutting cartridges, tooling joints, working overhead or applying in awkward positions. Although the product is virtually odourless and isocyanate-free, the working area should still be kept well ventilated during application and throughout the curing period. Avoid unnecessary contact with uncured adhesive sealant and clean accidental contamination promptly before curing begins. Do not eat, drink or smoke while handling the product. Wash hands thoroughly after use. Where Soudaseal 205FT is used in smaller rooms or enclosed spaces, continue ventilation until the adhesive has cured sufficiently for safe occupation.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eData Sheets\u003c\/h5\u003e\n\u003ch3\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/SOUDASEAL_205FT_TECH.pdf?v=1779897189\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eTechnical Data Sheet\u003c\/strong\u003e\u003c\/a\u003e\u003c\/h3\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/SOUDASEAL_205FT_TECH.pdf?v=1779897189\" rel=\"noopener\" target=\"_blank\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/SOUDASEAL_205FT_TECH_160x160.jpg?v=1779897218\" alt=\"\" style=\"float: none;\"\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/SOUDASEAL_205FT_COSHH.pdf?v=1779897177\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eSafety Data Sheet\u003c\/strong\u003e\u003c\/a\u003e\u003c\/h3\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/SOUDASEAL_205FT_COSHH.pdf?v=1779897177\" rel=\"noopener\" target=\"_blank\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/SOUDASEAL_205FT_COSHH_160x160.jpg?v=1779897218\" alt=\"\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/a\u003e\u003c\/div\u003e","brand":"Soudal","offers":[{"title":"White \/ 290ml Cartridge","offer_id":58166469263744,"sku":"SILSS205FT3W","price":3.89,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 290ml Cartridge","offer_id":58166469296512,"sku":"SILSS205FT3B","price":3.89,"currency_code":"GBP","in_stock":false},{"title":"Grey \/ 290ml Cartridge","offer_id":58166469329280,"sku":"SILSS205FT3G","price":3.89,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/soudaseal-205ft-flexible-tack-hybrid-adhesive-sealant-white-290ml-cartridge-smx-r-polymer-283.webp?v=1780475047","url":"https:\/\/www.platinumchemicals.co.uk\/products\/soudaseal-205ft-smx-hybrid-polymer-adhesive-sealant","provider":"Platinum Chemicals","version":"1.0","type":"link"}
