Cold Welding Compound CX80 CX-80 56 g — cold weld repair paste, metal bonding

CX80 CX-80 56 g cold welding compound is a hand-applied repair paste formulated for bonding and filling metal parts without the need for heat. The product is supplied as a ready-to-use paste that cures to form a solid repair, restoring structural continuity and sealing cracks, holes and worn surfaces. It is intended for small repairs, maintenance work and on-site emergency fixes where a durable metal-to-metal bond and gap filling are required.

Advantages

The cold weld repair paste adheres to a range of metals and provides mechanical strength after curing, allowing repaired areas to be drilled, filed and sanded. Its solvent-free, hand-mixable format makes it convenient for localized repairs and rapid application. Because it cures without heating, it reduces the need for additional tools and lowers the risk of heat-related distortion to surrounding parts.

Suitable for

• Repairing cracks and holes in metal housings and casings
• Filling worn or eroded surfaces on shafts, gears and fittings
• Bonding small metal parts where welding or brazing is impractical
• On-site emergency maintenance and temporary restorations

Key specifications

• Form: two-part hand-mixable paste supplied in a 56 g container
• Curing: room-temperature chemical cure without external heat
• Working time: short work time for shaping and application before initial set
• Mechanical finishability: can be drilled, tapped, filed and sanded after cure
• Adhesion: formulated for strong adhesion to common ferrous and non-ferrous metals

How to use

Prepare surfaces by cleaning and degreasing to remove rust, oil and contaminants. Cut or dispense equal portions of the two paste components and knead thoroughly until a uniform colour is achieved. Apply the mixed paste to the repair area, pressing firmly to ensure good contact and to eliminate air pockets. Shape or level the paste as required; allow the compound to cure fully at ambient temperature before machining or loading the repair.

Usage recommendations

For best results, abrade smooth surfaces to improve mechanical keying and ensure thorough degreasing before application. Avoid applying the paste to hot surfaces and allow adequate cure time before exposing the repair to mechanical stress or pressure. Store the product in a cool, dry place and follow safety instructions on the packaging regarding skin contact and ventilation.
