This high-strength cold welding glue is a two-part epoxy adhesive engineered for permanent metal repairs without heat. It cures to a rock-hard, heat-resistant bond with a tensile strength exceeding 25 MPa, making it ideal for structural fixes, sealing, and casting on metals, plastics, ceramics, and more. Features and Benefits
- High-Temperature Resistance (up to 120°C/248°F) - Maintains structural integrity for repairs on engine components, exhaust manifolds, and machinery parts exposed to heat.
- Exceptional Tensile Strength (>25 MPa) - Creates durable, load-bearing bonds that can withstand significant stress and vibration for long-lasting repairs.
- AB Two-Component Formula - Ensures a complete, uniform cure for maximum bond strength and chemical resistance when properly mixed.
- Versatile Substrate Bonding - Adheres strongly to iron, steel, aluminum, copper, ceramics, hard plastics, and wood for multi-material repairs.
- Waterproof and Chemical Resistant - Forms an impermeable seal that protects against corrosion, fuels, oils, and solvents in demanding environments.
- Minimal Shrinkage on Cure - Provides precise gap filling and maintains dimensional stability for accurate casting and mold repairs. Applications
- Automotive and Machinery Repair - Permanently fix cracked engine blocks, repair threaded holes, seal radiators, or rebuild worn metal parts.
- Plumbing and Appliance Maintenance - Seal leaks in pipes, tanks, and fittings or repair broken brackets and components on washing machines and dryers.
- DIY and Metal Fabrication - Bond metal sculptures, repair tools, create custom jigs, or fill voids in castings and molds.
- Household and Structural Repairs - Reinforce furniture joints, repair door handles, fix garden tools, or seal gaps in gutters and flashings. Note: For optimal results, clean and roughen surfaces before application. Mix equal parts of resin and hardener thoroughly until uniform in color. Full cure and maximum strength are achieved after 24 hours.
