Cold Weld Adhesive CX80 JBW — two-part metal repair adhesive for cold welding

CX80 JBW is a two-part cold weld adhesive formulated for bonding and repairing metal surfaces without the need for heat or traditional welding equipment. Supplied as separate resin and hardener components for manual mixing, this product restores damaged parts, seals joints and fills gaps on steel, cast iron and other metallic substrates. CX80 JBW is intended for workshop repairs, automotive maintenance and general metal restoration where welding or machining is impractical or would cause distortion.

Advantages

The two-part formulation cures at ambient temperature to form a hard, machinable and corrosion-resistant repair that bonds to a range of ferrous and non-ferrous metals. Manual mixing allows controlled working time and application to irregular surfaces and confined areas. Once cured, the material can be drilled, tapped, filed or sanded to restore functional geometry. The product eliminates the need for heat, reducing the risk of thermal distortion and allowing repairs on assembled components.

Suitable for

• Repairing cracks, holes and worn sections in steel and cast iron parts
• Sealing and rebuilding flanges, housings and threaded connections
• Automotive fixes such as patching engine components, oil pans and transmission housings
• General maintenance and workshop restorations where welding is impractical

Key specifications

• Two-component resin and hardener system mixed manually
• Cures at room temperature to a hard, machinable compound
• Suitable for use on steel, cast iron and many other metal surfaces
• Can be drilled, tapped, filed and sanded after curing
• Provides a corrosion-resistant repair once fully cured

How to use

Prepare mating surfaces by cleaning thoroughly to remove oil, grease, rust and loose material. Roughen smooth metal areas to improve mechanical adhesion. Mix the resin and hardener in the recommended ratio until a uniform colour and consistency is achieved, then apply the mixture to the repair area, shaping as required. Allow the adhesive to cure fully at ambient temperature before subjecting the repair to mechanical load or machining. Follow safety precautions and work in a well-ventilated area.

Usage recommendations

For best results, use on clean, dry surfaces and observe the manufacturer’s stated working and curing times. Avoid exposing the uncured mixture to moisture or contaminants. After curing, standard metalworking tools can be used to achieve final tolerances and surface finish.
