Soudabond 280 Power Spray Contact Adhesive

Health & Safety Recommendations

Use Soudal Soudabond 280 Power Spray Contact Adhesive only in well-ventilated areas and keep away from ignition sources because the propellant and solvent are flammable.

Wear suitable gloves and safety goggles, and consider a respirator if ventilation is limited. Avoid breathing vapour or spray mist and prevent prolonged skin contact. In the event of eye contact, rinse immediately with clean water and seek medical advice.

Do not smoke while spraying, do not use on or near live electrics, and do not expose the aerosol to direct sunlight or temperatures above 50°C. Store upright in a cool, dry place out of reach of children and dispose of empty cans responsibly.

Substrate Suitability

For best results the parts to be bonded must be flat, well fitting and dimensionally stable so that full-face contact is achieved.

The adhesive shows very good adhesion to common mounting materials used in construction, fit-out, upholstery and automotive work, including metals and steel, timber and wood-based boards, laminate, many plastics and rubbers, ceramics, cork, leather, cardboard, paper and polystyrene foams.

It is not suitable for PE, PP or PTFE. Soft plastics that contain plasticisers may leach over time and can weaken the bond, so test these carefully.

Although the formulation bonds some low-energy surfaces, always carry out a preliminary adhesion and compatibility test on every substrate and combination before committing to the full job.

Surface Preparation

Ensure both bonding faces are clean, dry and free from dust, oil, release agents and loose material. Degrease where necessary with an appropriate solvent wipe and allow all solvent to evaporate completely.

Lightly abrade very smooth or glossy surfaces, then remove dust thoroughly to improve mechanical key and achieve an even adhesive film. Bring all components into the recommended application temperature band of 5°C to 30°C. Dry-fit the parts to confirm alignment and coverage because contact adhesives grip on contact and allow very little repositioning.

Application Method

Shake the can vigorously immediately before use. Hold the aerosol upright throughout application and fully depress the nozzle. Maintain a steady distance of about 5cm to 10cm from the surface and apply the adhesive to both faces in a uniform web pattern.

Use parallel passes with approximately half overlap so the entire area is covered by two light coats rather than a single heavy coat, which gives more consistent coverage and stronger bonds.

Porous faces may need a slightly richer application to achieve a continuous film. Allow the solvent to evaporate for about three minutes until the film is dry to the touch yet distinctly tacky. The correct condition is when the adhesive does not transfer to a fingertip but still feels aggressively tacky. Carefully align the parts and bring the coated faces together. Apply firm, even pressure over the full bond area using a roller, rubbing block or press. Pressure, not the length of time under compression, determines the ultimate bond strength, although a typical pressing time of fifteen to thirty seconds is a useful guide for achieving intimate contact across the bond line. After spraying, invert the can and press the nozzle until only propellant emerges to clear the valve and prevent clogging before storage.

Coverage

Typical consumption is about 125ml/m² per side on smooth, non-porous substrates. Because both surfaces must be coated, allow roughly 250ml/m² for a complete bond.

Actual usage will vary with surface texture, porosity, spray distance and technique.

Drying Time

At normal conditions the evaporation time before bonding is about three minutes. The open time is up to about 120 minutes provided the adhesive film remains clean and tacky.

Bonds are hand-tight immediately after pressure is applied and continue to build to high final strength over the next twenty-four hours. Avoid loading or stressing the assembly until the bond has cooled and stabilised.

Cleaning

Remove uncured overspray or squeeze-out promptly with a suitable solvent cleaner applied to a lint-free cloth, working from clean areas towards the contamination to avoid smearing.

Test the solvent first on sensitive plastics, coated metals and decorative finishes. Once cured, residues must be removed mechanically with care not to damage the substrate. Masking edges and maintaining the correct spray distance will greatly reduce overspray and subsequent clean-up.

Limitations

Soudabond 280 Power Spray Contact Adhesive is a contact system for flat, well-matched surfaces and is not a gap filler. It is not suitable for PE, PP or PTFE and is not recommended for substrates with a high plasticiser content unless successful long-term tests have been completed.

Do not use in applications subject to continuous water immersion or where standing water can invade the bond line. Observe the service temperature range from −20°C to 100°C and avoid exposure beyond these limits.

Other Information

Q) What is Soudal Soudabond 280 Power Spray Contact Adhesive and how does it work?

A) Soudal Soudabond 280 Power Spray Contact Adhesive is a high-strength aerosol contact adhesive for bonding flat, well-fitting surfaces quickly and cleanly. The pressurised can applies a controlled web pattern that creates an even adhesive film over large areas in a short time. After a short evaporation period, the two coated faces are brought together and pressed firmly to form an instant, hand-tight bond that continues to build to a very high final strength. The formulation is based on synthetic rubber in a physical drying system, so strength develops as solvents evaporate rather than through chemical curing. It is compatible with a wide range of construction, fit-out and automotive materials, including polystyrene, and has a short evaporation time that speeds workflow. Because it is a true contact adhesive it performs best where full-face contact is achievable and uniform pressure can be applied across the bond line.

Q) Which materials will Soudal Soudabond 280 Power Spray Contact Adhesive bond successfully?

A) Soudal Soudabond 280 Power Spray Contact Adhesive adheres strongly to metals and steel sheet, timber and wood-based boards, high-pressure laminates, many plastics and rubbers, cork, leather, cardboard, paper, ceramics and rigid foams including polystyrene. This breadth of compatibility makes it useful for laminating countertops, bonding veneers to MDF and plywood, fixing trims and edging, assembling packaging and displays, and attaching foams and fabrics in upholstery and vehicle interiors. As with any contact adhesive, it is intended for flat, well-matched parts rather than gap filling or heavily textured substrates. It is not suitable for polyethylene, polypropylene or PTFE, and plastics containing high levels of plasticiser should be tested because plasticiser migration can soften contact bonds over time. Always complete a small adhesion and compatibility test on the exact material combination before committing to full production.

Q) How does Soudal Soudabond 280 differ from Soudabond 265 Classic Spray in practice?

A) Soudal Soudabond 280 Power Spray Contact Adhesive is formulated for a faster rise to handling strength and a higher ultimate bond than Soudabond 265 Classic Spray. In practical terms, Soudabond 280 reaches the correct tack more quickly, grips more assertively on contact and maintains adhesion under load during immediate processing, such as trimming, edging and transport. This makes it a better choice for demanding assemblies, heavier laminates and components that are fixed under slight tension or handled soon after bonding. Both products share user-friendly aerosol delivery, even web pattern coverage and the absence of toluene and methylene chloride, but Soudabond 280 is the step-up option when maximum bond line performance and speed are priorities. Where substrates are very lightweight and loads are modest, Soudabond 265 remains a capable, economical choice, while Soudabond 280 provides additional headroom for more intensive fit-out and manufacturing tasks.

Q) What are the best applications for Soudal Soudabond 280 Power Spray Contact Adhesive?

A) Typical uses include laminating high-pressure laminate and veneer to MDF, chipboard or plywood in joinery and shopfitting, edge banding and lippings that require an even, controllable film, upholstery and acoustic panel work involving fabrics, felts, leathers and foams, and automotive or transport trim assemblies such as headliners, door cards and acoustic pads. It is also effective for securing flexible floor coverings and threshold trims on flat substrates during repairs and light installations, and for packaging, display and craft tasks that involve cardboard, paper and polystyrene forms. The strength under load and rapid processing capability make it ideal where bonded parts need to be moved or machined soon after pressing. For best results, choose jobs where both faces are flat, clean and dimensionally stable so full-face contact and firm, uniform pressure can be achieved during assembly.

Q) How should I prepare surfaces before using Soudal Soudabond 280 Power Spray Contact Adhesive?

A) Good preparation is essential for a durable contact bond. Ensure both faces are clean, dry and free from dust, oil, release agents and loose material. Degrease where necessary with a suitable solvent wipe and allow complete evaporation. Very smooth or glossy surfaces benefit from a light abrasion to improve mechanical key, followed by thorough dust removal with a vacuum and clean cloth. Bring both parts into the recommended application temperature range of five to thirty degrees Celsius so spray behaviour and drying are predictable. Dry-fit components to prove alignment because contact bonds allow very little repositioning once the faces meet. Mask margins where appearance is critical, keep the work area ventilated and clear overspray risks, and have a roller or rubbing block ready so consolidation pressure can be applied immediately after the parts are brought together.

Q) What is the correct application method for Soudal Soudabond 280 Power Spray Contact Adhesive?

A) Shake the can vigorously, hold it upright and depress the nozzle fully to produce a consistent web pattern. Spray from about five to ten centimetres, moving smoothly and applying parallel passes with roughly half overlap for an even film. Coat both bonding faces, since contact systems develop maximum strength through adhesive-to-adhesive contact. Porous faces may need a slightly richer application to achieve a continuous film, while non-porous faces are best served by two light coats rather than one heavy coat. Allow a short evaporation period until the film is dry to the touch yet aggressively tacky, then carefully align and bring the faces together. Apply firm, uniform pressure over the whole area using a roller or rubbing block, paying particular attention to edges and cut-outs. After spraying, invert the can and purge until only propellant emerges to keep the valve clear for next use.

Q) How long is the evaporation and open time for Soudal Soudabond 280 Power Spray Contact Adhesive?

A) At normal ambient conditions the evaporation time before mating is about three minutes. This is the period required for solvents to flash off so the film feels dry to the touch but remains strongly tacky. The open time extends up to approximately one hundred and twenty minutes provided the adhesive film stays clean and tacky, which allows staged assembly of multiple components. Temperature, humidity and film thickness all influence timing. Cooler, more humid environments and heavier coats extend evaporation time, while warm, dry conditions shorten it. Do not assemble while the film is still wet, as trapped solvent can weaken the bond. Once the faces meet, apply consolidation pressure immediately. Hand-tight strength is achieved on pressing, with final strength continuing to build over the next twenty-four hours as residual solvent dissipates and the film stabilises.

Q) What coverage can I expect from Soudal Soudabond 280 and how should I estimate usage?

A) As a planning guide, consumption is about one hundred and twenty-five millilitres per square metre per side on smooth, non-porous materials. Because both faces must be coated, allow approximately two hundred and fifty millilitres per square metre for a complete bond. Substrate texture, porosity, spray distance and operator technique will influence the actual figure. Two light, overlapping coats generally produce better control and stronger bonds than a single heavy coat, while keeping the nozzle close to the work and masking edges reduces overspray and waste. Record real-world usage on early jobs so estimates can be refined for future work. For very porous faces, consider a light pre-coat to seal the surface, followed by the standard application on both faces to achieve a continuous film and consistent bond line.

Q) When can bonded parts be handled and how strong is the final bond from Soudal Soudabond 280?

A) Soudal Soudabond 280 provides an instant, hand-tight bond as soon as the coated faces are pressed together firmly after the correct evaporation period. This immediate grip supports rapid handling, trimming and edging in production environments. The bond continues to strengthen over the next twenty-four hours to reach a very high final strength that resists creep and maintains adhesion under load. Because contact systems rely on pressure rather than time under pressure, the quality of consolidation is critical. Use a roller or rubbing block to apply firm, uniform pressure across the entire area, focusing on edges, corners and cut-outs. Weak bonds are usually traced to inadequate film coverage, mating while still wet, or insufficient pressing pressure. Design joints for full-face support and avoid peel-type loading if long-term stress will be present.

Q) Is Soudal Soudabond 280 Power Spray Contact Adhesive safe to use on polystyrene and other sensitive foams?

A) Yes. Soudal Soudabond 280 is compatible with polystyrene foams, including EPS and XPS, which are often attacked by conventional contact adhesives. The controllable web pattern allows a light, even film that does not flood delicate surfaces, and the short evaporation time supports efficient lay-up. As with any foam, avoid over-application, allow the correct evaporation period and apply even pressure to achieve intimate contact without crushing the substrate. For mixed assemblies such as laminate-to-foam, apply a slightly richer film to the denser face and a lighter film to the foam, then check a small test area for surface softening or imprinting before proceeding with full-size parts. This approach protects the foam surface while delivering the high final strength that Soudabond 280 is known for.

Q) What temperature range and service conditions suit Soudal Soudabond 280 Power Spray Contact Adhesive?

A) Apply within five to thirty degrees Celsius so spray pattern and drying behaviour are predictable and consistent. Once fully stabilised, the typical service temperature range is approximately minus twenty degrees Celsius to one hundred degrees Celsius, which covers the vast majority of interior assemblies and many light-duty applications subjected to moderate warmth. Avoid bonding in very cold or damp conditions where condensation may form on surfaces, as this inhibits adhesion and prolongs drying. The product is not designed for continuous water immersion or for permanently wet locations, so detail joints to shed water and select an alternative system for submerged service. For exterior use in sheltered areas, confirm that both substrates are suitable and protect the bond line from prolonged standing water and direct weathering for best longevity.

Q) Are there any limitations or materials where Soudal Soudabond 280 should not be used?

A) Soudal Soudabond 280 is a contact system for flat, well-matched surfaces and is not intended for gap filling, structural joints or heavily textured substrates. It should not be used on polyethylene, polypropylene or PTFE, and caution is advised with soft, highly plasticised plastics because plasticiser migration can reduce long-term bond strength. The adhesive is not suitable for joints that will be permanently immersed or exposed to continuous liquid water. While it tolerates moderate warmth in service, sustained temperatures above one hundred degrees Celsius fall outside its performance envelope. If repositioning is required, this is not the right technology, because contact bonds grip on touch. For critical assemblies, run a representative trial to validate coverage, evaporation time, pressure and long-term compatibility before committing to production.

Q) What health and safety measures should I follow when using Soudal Soudabond 280 Power Spray Contact Adhesive?

A) Use only in well-ventilated areas and keep away from ignition sources because both propellant and solvent are flammable. Do not smoke during application. Wear suitable gloves and safety goggles, and consider a respirator where ventilation is limited to avoid inhaling vapour or spray mist. Prevent prolonged skin contact and wash with soap and water if contamination occurs. In the event of eye contact, rinse immediately with clean water and seek medical advice. Do not spray onto live electrical equipment or hot surfaces. Keep the aerosol out of direct sunlight and away from temperatures above fifty degrees Celsius. Store upright in a cool, dry place, keep out of reach of children and dispose of empty cans and solvent wipes responsibly in line with local regulations.

Q) How do I minimise overspray and clean up after using Soudal Soudabond 280?

A) Plan the work area, mask margins and keep the nozzle five to ten centimetres from the surface to reduce overspray. Use smooth, overlapping passes and two light coats rather than one heavy coat to improve control. For uncured adhesive on adjacent surfaces, wipe promptly with a suitable solvent cleaner applied to a lint-free cloth, always testing the solvent first on sensitive finishes, plastics and coated metals. Work from the clean area towards the contamination to avoid smearing. Once fully cured, residues must be removed mechanically with care not to damage the substrate. To prevent nozzle blockage, invert the can after use and spray until only propellant emerges, which purges the valve and leaves the can ready for the next session with consistent spray performance.
