Repair and restore your metal equipment with the Industrial Strength A&B Cold Weld Metal Repair Paste. Designed as a high-performance alternative to torch welding, this heavy-duty adhesive provides a permanent and incredibly strong bond. Whether you are patching a cracked engine block, sealing a leaking pipe, or repairing industrial machinery, this two-part casting agent is engineered to withstand extreme conditions.

This epoxy-based system consists of a resin and a hardener that, when mixed, form a rock-hard surface that can be drilled, tapped, filed, sanded, and painted just like real metal.

Engineered for Extreme Performance

• Superior Heat Resistance: Capable of withstanding temperatures up to 150°C (302°F). This makes it ideal for automotive repairs, heating systems, and high-friction machinery.

• 100% Waterproof & Chemical Resistant: Once fully cured, the bond is impervious to water, oil, gasoline, and most household chemicals. It provides a reliable seal for plumbing and fuel tanks.

• Permanent Cold Weld: Developed to provide an industrial-grade bond. The final result is often stronger than the original material, offering high impact and tensile strength.

• Versatile Material Bonding: Works flawlessly on a wide variety of surfaces including steel, iron, aluminum, brass, copper, and even some rigid plastics or ceramics.

• No Shrinkage: The formula is designed to maintain its volume during the curing process, ensuring a precise fit for gaps and cracks.

How to Achieve a Professional Repair

1. Surface Prep: Ensure the area is clean, dry, and free of oil or rust. For the strongest bond, slightly roughen the surface with sandpaper or a wire brush.

2. Mix: Squeeze equal amounts from Tube A (Resin) and Tube B (Hardener) onto a disposable surface. Mix thoroughly until the paste is a uniform grey color.

3. Apply: Spread the paste onto the repair area within 20 minutes of mixing. Press firmly to ensure it fills all gaps or cracks.

4. Cure: Allow the paste to set. It will be touch-dry in about 1–4 hours and fully cured to maximum strength in 24 hours.

5. Finish: Once rock-hard, you can sand, grind, or paint the repair to match the surrounding surface.

Common Applications

• Automotive: Repairing radiator leaks, cracked engine blocks, or fuel tank punctures.

• Plumbing: Sealing pipes, water tanks, and metal fittings.

• Industrial: Fixing casting defects, sand holes, and machinery cracks.

• Household: Restoring metal furniture, door hinges, and garden tools.

Safety Tip: Use in a well-ventilated area and avoid direct skin contact with the unmixed paste. If contact occurs, wash thoroughly with soap and water.
