Soudal Freeze Spray

Health & Safety Recommendations

Read the label and safety data sheet in full before use. Use Soudal Freeze Spray only in well-ventilated areas and keep away from ignition sources, hot surfaces and open flames.

Treat the aerosol as flammable and pressurised; do not smoke during use. Wear Cold-Resistant Gloves to protect against frostbite and thermal shock, and use suitable eye protection to guard against splashes and flying debris released during disassembly.

Avoid breathing vapour; do not deliberately inhale. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice if irritation persists. Prolonged skin contact with super-cooled liquid or metal may cause cold burns; warm the affected area gently with tepid water and obtain medical attention if required.

Ensure that electrical and electronic equipment is fully powered down and isolated prior to application. After use around electrical equipment, allow ample time for complete evaporation and thorough aeration before restoring power to minimise the risk of igniting trapped vapour pockets.

Observe normal workshop hygiene, wash hands after use, and dispose of empty cans and waste materials in accordance with local regulations. Do not puncture or incinerate the container, even when empty.

Substrate Suitability

Soudal Freeze Spray is intended for metal parts and assemblies where corrosion or fretting has seized the joint. Typical substrates include steel and stainless fixings, alloy components, bolts, nuts, studs, pins, shafts, hinges, pulleys, collars, bearings and other moving parts.

It may also be used for localised cooling on electrical and electronic components for thermal diagnostics and to limit heat spread during soldering. Always assess compatibility on plastics, elastomers, painted and lacquered finishes, composites and brittle materials; extreme thermal shock can stress or embrittle temperature-sensitive substrates and coatings.

Where in doubt, carry out a small trial on an inconspicuous area or consult the equipment manufacturer.

Surface Preparation

Isolate the equipment and make the work area safe. For mechanical assemblies, remove loose rust, dirt and surface contaminants with a wire brush to expose the joint line and thread flanks; this improves access for the cold-shock and any follow-on penetrant.

Where practical, pre-tension or gently “nip” the fastener so the joint is ready to move as soon as the bond is broken. Mask adjacent delicate components and plastics that may be affected by sudden cooling. For electrical and electronics work, switch off and unplug the device, discharge capacitors where applicable, and ensure good ventilation around the board or enclosure.

Position extraction to remove vapours and any condensation that may form on cold surfaces.

Application Method

Shake the can briefly before use. Fit the precision straw if supplied for accurate targeting, or use the standard nozzle for broader coverage. Hold the nozzle 10–20 cm from the target and apply short, controlled bursts directly onto the seized interface, rotating around the joint so the cold-shock reaches the full circumference.

The treated area will drop rapidly to approximately −50 °C; allow a few seconds for contraction and micro-cracking within the corrosion layer. Attempt movement using the correct tool, applying steady, even torque. For stubborn fixings, cycle the process: freeze, gently work the fastener a fraction of a turn, then freeze again.

Once initial movement is achieved, you may introduce a penetrating lubricant to take advantage of the capillary pathways created by the cold-cracking effect, then work the joint back and forth until fully free. The aerosol is equipped with a 360° valve and can be used in any orientation to reach awkward locations such as under dashboards, inside engine bays and behind panels.

For electronics, apply brief bursts to the specific component or trace to localise cooling; avoid prolonged chilling that could induce condensation or thermal stress. After any use on electrical equipment, allow complete evaporation and ventilate thoroughly before re-energising.

Cleaning

The formulation evaporates rapidly and typically leaves minimal residue. Wipe away any condensed moisture, loosened debris or dislodged corrosion products with a clean, dry cloth.

After disassembly, clean threads and mating surfaces mechanically, then protect with an appropriate anti-corrosion coating or Soudal Assembly Lubricant to prevent recurrence. If overspray contacts sensitive finishes, warm gently to ambient and wipe clean. Keep the actuator and extension straw free of debris to maintain an accurate spray pattern.

Limitations

Do not use on energised electrical equipment or in areas with potential ignition sources until vapours have fully dispersed. Do not rely on the product as a lubricant or long-term corrosion inhibitor; it is a release aid and local cooling tool.

Avoid extended application on brittle substrates, tempered glass, ceramics, thin castings, stressed plastics or paint films that may crack under thermal shock. Do not use in oxygen-deficient atmospheres or confined spaces without appropriate ventilation and gas monitoring. The product will not overcome severe mechanical damage, galling or gross thread deformation where cutting or mechanical repair is required.

Always use correct-size tools and safe disassembly techniques; excessive force can shear fasteners even after cold-shocking. Store and transport the aerosol upright where possible, away from direct sunlight and temperatures above 50 °C.

Other Information

Soudal Freeze Spray delivers an immediate cold-shock, cooling localised areas down to around −50 °C to disrupt rust and corrosion bonds and assist with rapid maintenance and repair.

It is equally suited to daily maintenance tasks and tougher applications where standard penetrating lubricants alone may not be effective, and it supports electronics work by limiting heat spread during soldering and by aiding thermal fault-finding. The content of this guidance reflects testing and practical experience but is general in nature and does not constitute a warranty or liability.

Conditions of use vary widely; it is the responsibility of the user to determine, by their own tests and risk assessment, whether the product is suitable for the intended application and to adopt safe systems of work.

Q) What is Soudal Freeze Spray and what problem does it solve?

A) Soudal Freeze Spray is an immediate-action troubleshooting aerosol that delivers a powerful cold-shock to rapidly cool metal components and seized assemblies to approximately −50°C. The sudden temperature drop forces the metal to contract and fractures the brittle rust and oxide layer at a microscopic level, so the bond between threads and mating faces is disrupted. This means stubborn bolts, nuts, studs, pins, hinges and similar fittings can be released with far less torque and without resorting to hammers, heat torches or cutting wheels. The formulation is odourless, fast-evaporating and designed with high capillary power to penetrate tight tolerances as parts contract and then re-expand. A 360° valve allows spraying in any orientation for precise work in cramped or overhead locations. Whether you are tackling routine maintenance or a heavily corroded assembly that laughs at ordinary penetrating oil, Soudal Freeze Spray provides a clean, controlled first response that saves time, reduces collateral damage and preserves components for re-use.

Q) How does Soudal Freeze Spray work to free seized bolts and corroded parts?

A) Soudal Freeze Spray projects an intense refrigerant jet that drops the surface temperature of the target part to around −50°C within seconds. This induces rapid thermal contraction of the metal and creates a network of micro-cracks through the corrosion layer, breaking the adhesion between oxidised surfaces. As the component begins to return towards ambient temperature, the product’s low viscosity and high capillary action wick into the newly opened pathways at the thread flanks and interfaces. The combination of mechanical shock and capillary ingress reduces break-away torque dramatically, so a controlled pull on the correct tool will usually start movement without shearing the fastener. By avoiding heat, you protect adjacent seals, coatings and plastics, and you avoid the sparks, debris and rework associated with cutting. Used methodically freeze, attempt movement, freeze again, Soudal Freeze Spray converts a static, bonded joint into one that can be worked back and forth until fully released.

Q) What are the key technical features of Soudal Freeze Spray that make it effective?

A) Soudal Freeze Spray is formulated to deliver local cooling to approximately −50°C with a focused jet that reaches tight interfaces fast. The aerosol incorporates a 360° any-angle valve so you can spray upright, sideways or inverted without loss of performance, ideal under dashboards, in engine bays or behind panels. The chemistry is odourless for comfortable use in enclosed spaces, and it evaporates quickly to minimise clean-up and allow swift progression to the next maintenance step. Crucially, the liquid exhibits high capillary power, so as the metal contracts and then re-expands it is drawn deep into threads, splines and press fits. This makes the cold-shock more than a superficial chill; it becomes a functional release aid that exploits the physical movement of the joint. Because it is a cooling and release medium rather than a lubricant, it complements penetrating oils and anti-corrosion treatments applied after initial movement is achieved.

Q) Where should Soudal Freeze Spray be used in mechanical maintenance and repair?

A) Soudal Freeze Spray excels anywhere corrosion, heat cycling or fretting has locked parts together. Typical targets include exhaust clamps, manifold studs, brake and suspension fixings, pulley hubs, press-fit collars, agricultural linkages, marine deck fittings, hinges and machine screws on frames and plant. It is particularly useful around heat-sensitive surroundings where a torch would risk damage to bearings, seals, paint, wiring looms or adjacent plastics. In workshops and fabrication shops it speeds strip-downs of jigs and fixtures; on site it helps with anchors and fixings in tight service voids. Because the can sprays at any angle, you can reach recessed fasteners and overhead components without dismantling half the machine. The result is faster, safer disassembly with fewer broken studs, less tool wear and a far better chance of preserving threads for clean reassembly with correct torque.

Q) Is Soudal Freeze Spray suitable for automotive, plant and marine applications?

A) Yes, Soudal Freeze Spray is well suited to vehicle, plant and marine maintenance where exposure to heat, water and salt accelerates corrosion. On vehicles it helps release exhaust hardware, EGR and turbo studs, brake and suspension fasteners, and stubborn sensors or fittings without risking heat damage. In plant rooms and on construction equipment it frees seized pins, brackets, guards, pulleys and housings with reduced downtime. In marine settings it assists with winch fixings, deck hardware and engine auxiliaries where salt-driven corrosion is common. The odourless formula and fast evaporation support use in confined spaces, while the 360° valve enables access under bulkheads or behind panels. After release, clean the threads and protect with an appropriate lubricant or anti-seize to resist future corrosion, Soudal Freeze Spray gets you moving; correct aftercare keeps you moving.

Q) Can Soudal Freeze Spray be used for electronics and electrical work?

A) Soudal Freeze Spray is valuable for electronics and electrical tasks that benefit from localised cooling. During soldering it can be used to limit heat spread to nearby components, protecting heat-sensitive parts and delicate plastics by quickly drawing down local temperature. For diagnostics, selective chilling of individual components, ICs or circuit zones can provoke or suppress thermally intermittent faults, helping you isolate issues without full strip-down. Always power down and isolate equipment before application, discharge capacitors where applicable, and use brief, targeted bursts to avoid condensation or undue thermal stress. Allow complete evaporation and ventilate thoroughly before re-energising to minimise the risk of igniting vapour pockets. Used with care, Soudal Freeze Spray provides repeatable, precise thermal control that accelerates rework and fault-finding while reducing the likelihood of heat-related collateral damage.

Q) How do I apply Soudal Freeze Spray to free a seized fastener step by step?

A) Start by making the area safe and brushing away loose rust and dirt so the joint line is visible. Fit the precision straw if supplied, hold Soudal Freeze Spray 10–20 cm from the target and apply short, controlled bursts around the full circumference of the interface to ensure even cold-shock. Wait a few seconds to allow contraction and micro-cracking within the oxide layer. Apply steady, even torque with the correct-size tool, avoid snatching. If there is no movement, repeat the freeze and try to ‘nip’ the fastener a fraction of a turn back and forth. Once initial movement is achieved, you can introduce a penetrating lubricant to exploit the capillary pathways created by the cold-cracking effect, then continue working the joint progressively. For stubborn cases, cycle freeze–move–freeze several times rather than escalating to impact or heat. The 360° valve lets you spray in any orientation to reach awkward recesses without dismantling surrounding parts.

Q) Does Soudal Freeze Spray replace penetrating lubricants, or should they be used together?

A) Soudal Freeze Spray and penetrating lubricants are complementary. The cold-shock provides the breakthrough by fracturing the corrosion layer and reducing the interference fit, while the high capillary action draws the fluid into the newly opened pathways. Once you have achieved the first hint of movement, a quality penetrant can be introduced to lubricate and further loosen the joint. Working the fastener back and forth allows the penetrant to travel along the flanks and threads that the freeze cycle has opened up. This combined approach is often faster and more reliable than extended soaking with penetrants alone, and it avoids the risks associated with heat. After disassembly, clean and protect the components with anti-corrosion products or anti-seize so the problem is less likely to recur. Think of Soudal Freeze Spray as the controlled sledgehammer that creates the gap your penetrant needs.

Q) What practical tips will improve results when using Soudal Freeze Spray?

A) Preparation and technique make the difference. Wire-brush the joint first to expose the interface, and if possible pre-tension or ‘nip’ the fastener so it is ready to move as soon as the bond breaks. Use short, targeted bursts of Soudal Freeze Spray while rotating around the joint to chill it evenly, and wait a few seconds before applying torque to let micro-cracks propagate. Work the fastener back and forth in small increments rather than attempting a full turn at once. Re-apply the freeze cycle between movements for tough cases, and add penetrant only after you’ve achieved initial motion to exploit the opened capillaries. Protect nearby plastics and brittle finishes from overspray and thermal shock, and always use the correct-size tools to avoid rounding. Patience beats force; several controlled cycles will usually free a joint with less risk than a single aggressive heave.

Q) What safety precautions should I follow when using Soudal Freeze Spray?

A) Treat Soudal Freeze Spray as a flammable, pressurised aerosol and use it only in well-ventilated areas, well away from ignition sources, hot surfaces and open flames. Wear cold-resistant gloves and suitable eye protection; the super-cooled liquid and metal can cause frostbite-like cold burns, and released debris can become airborne when a joint breaks free. Avoid breathing vapour and never deliberately inhale; the product is for mechanical effect, not continuous exposure. Power down and isolate electrical equipment before application, and allow complete evaporation with thorough ventilation before re-energising. Do not puncture or incinerate the can, even when empty, and store it below 50°C out of direct sunlight. As with all maintenance operations, work to a site risk assessment, keep hands clear of pinch points during release, and replace any damaged fasteners rather than forcing a compromised part back into service.

Q) Which materials and assemblies are compatible with Soudal Freeze Spray, and what should I avoid?

A) Soudal Freeze Spray is intended for metals, steel, stainless, many alloys, and for mechanical assemblies such as bolts, studs, pins, shafts, pulleys and hinges. It can also be used for localised cooling on electrical and electronic components when the equipment is isolated. Exercise caution with brittle substrates and temperature-sensitive finishes: tempered glass, thin castings, ceramics, stressed plastics, composites and delicate paint films may crack or craze under severe thermal shock. Where plastics, elastomers or lacquered surfaces sit adjacent to the target, shield them from overspray and work in short bursts. If compatibility is uncertain, perform a small, inconspicuous trial or consult the equipment manufacturer. Remember that Soudal Freeze Spray is not a lubricant or corrosion inhibitor; it is a cooling and release aid that should be followed by cleaning and protection once the joint is free.

Q) What are the limitations of Soudal Freeze Spray and when might it not be the right solution?

A) Soudal Freeze Spray will not overcome gross mechanical damage, heavy galling, cross-threading or severe deformation where cutting or mechanical repair is unavoidable. It is not suitable for use on energised electrical equipment, in oxygen-deficient atmospheres or in unknown atmospheres that could be immediately dangerous to life or health. Prolonged chilling of brittle or temperature-sensitive materials can cause cracking, and overspray onto delicate finishes may induce stress crazing. The product is a release aid and local cooler, not a long-term lubricant, sealant or rust preventative, so you must follow up with appropriate protection. As with any aerosol, use is restricted near ignition sources and in confined spaces without ventilation. If repeated freeze cycles and correct tools fail to initiate movement, escalate to mechanical methods with care rather than applying excessive force that risks shearing the fastener.

Q) How should I store and transport Soudal Freeze Spray to keep it performing well?

A) Store Soudal Freeze Spray upright in a cool, dry place away from direct sunlight, heaters and open flames, and keep it below 50°C to protect the can and valve. Avoid leaving aerosols in vehicles on hot days or in freezing conditions that could affect spray behaviour. Keep the actuator and any extension straw clean so the jet remains precise for capillary targeting. Transport in a way that prevents puncture or crushing, ideally in a tool case compartment where the can cannot roll or be struck. Rotate stock so older cans are used first, and always read the label for specific storage advice. Proper storage and handling ensure consistent, powerful cold-shock when you need it, and they reduce the small but real risks associated with pressurised, flammable aerosols.

Q) What should I do after Soudal Freeze Spray has freed the joint to prevent the problem returning?

A) Once Soudal Freeze Spray has helped you achieve movement, fully disassemble and clean the components. Brush threads and mating faces to remove loosened corrosion and debris, then inspect for wear or damage and replace any compromised parts. Dry the area and apply a suitable lubricant, anti-seize or corrosion-inhibiting coating before reassembly to protect against future bonding. Re-torque fasteners to the manufacturer’s specification and, where appropriate, use fresh washers, gaskets or thread treatments. In harsh environments, marine, winter roads, chemical exposure, consider additional protective measures such as barrier waxes or regular maintenance checks. The freeze cycle gets you out of trouble quickly; a brief clean-and-protect routine ensures you do not meet the same seized joint the next time the machine needs attention.

Q) How clean is Soudal Freeze Spray in use, and is there much residue to remove?

A) Soudal Freeze Spray is designed for clean operation. The refrigerant evaporates rapidly, typically leaving minimal residue so you can move straight to mechanical work, lubrication or reassembly. Any condensed moisture from ambient air and loosened oxide flakes should be wiped away with a clean, dry cloth. If overspray contacts sensitive surfaces, allow them to return to ambient temperature and wipe gently; persistent marks are uncommon due to the fast-evaporating nature of the product. Keep the nozzle and straw clear of debris to maintain a tight, accurate spray pattern for future tasks. This clean behaviour is particularly helpful in confined spaces and around finished components where solvent cleaning would add unnecessary time.

Q) How does Soudal Freeze Spray compare with using heat, impact tools or cutting methods?

A) Soudal Freeze Spray offers a controlled, low-risk alternative to brute-force and high-heat approaches. Unlike a torch, it avoids damaging adjacent seals, coatings and heat-sensitive parts, and it eliminates the fire hazards associated with open flames and sparks. Compared with heavy impact, it reduces the risk of thread damage, bearing brinelling and collateral harm to housings. Against cutting discs and grinders, it avoids debris, rework and the need to drill out studs or chase threads after breakage. In many cases, a freeze-and-work cycle followed by a penetrant will free the joint faster than soaking alone, with far less risk and mess. There will always be situations demanding mechanical removal, but starting with Soudal Freeze Spray usually shortens the job and preserves parts, which pays back immediately in labour, consumables and downtime.

Q) What troubleshooting steps should I take if Soudal Freeze Spray does not release the fastener immediately?

A) If the joint refuses to budge, step back and refine your process. Confirm you have fully exposed the interface with a wire brush and that you are chilling the entire circumference. rotate the straw as you spray. Allow a few seconds after each burst for contraction and micro-cracking, then apply steady torque with the correct-size tool; avoid sudden impacts that can shear a weakened fastener. Cycle freeze–move–freeze several times, aiming for tiny back-and-forth movements to propagate the fracture through the oxide layer. Introduce a penetrant only after initial movement to ride the capillaries created by the cold-shock. If the location permits, tap the head lightly with a hammer between cycles to help break the bond without overloading the shank. When repeated cycles fail, reassess: heat-resistant nearby parts, thread condition and access may dictate switching to mechanical extraction, but you will have attempted the lowest-risk method first with Soudal Freeze Spray.
