AB Cold Weld Metal Repair Paste – Extra Strong Casting Adhesive

Fix machinery, casting defects, and metal surfaces fast with this Extra Strong AB Cold Weld Metal Repair Paste. This two-part epoxy-style casting adhesive mixes at a simple 1:1 ratio (Part A : Part B) and cures to an iron-gray, rock-hard finish that bonds, seals, and rebuilds metal and machinery components without heat or specialist tools.

Key Features

Extreme Bond Strength: Industrial-grade two-part formula creates a durable, high-strength bond on metal, cast iron, aluminum, and more.
Wide Temperature Resistance: Performs reliably from -60°C to +200°C, making it suitable for demanding mechanical and industrial environments.
Fast & Predictable Cure: Reaches initial solidification in just 1 hour; achieves full cure strength within 12 hours.
Cold Application – No Heat Required: Apply directly to cleaned surfaces with no welding equipment or open flame needed.
Flexible Size Options: Available in 20g, 50g, 70g, 100g, 200g, 300g, and 500g to match your project scale — from small repairs to large casting defects.
2-Year Shelf Life: Long-lasting formula stays ready when you need it.
Machinable After Curing: Once fully hardened, the repair area can be filed, sanded, drilled, and finished just like solid metal.
Iron Gray Finish: Blends naturally with most metal surfaces for a clean, professional result.

Ideal Applications

Casting defect repair on machinery and equipment
Metal bonding, sealing, and gap filling
Rebuilding worn or damaged metal parts
Industrial maintenance and on-site repairs
Automotive and mechanical component bonding

How to Use

Prepare the Surface: Clean the repair area thoroughly — remove grease, rust, and loose particles. The surface must be clean and dry.
Mix: Dispense equal volumes of Part A and Part B (1:1 ratio) and mix together until a uniform color and consistency is achieved.
Apply: Press the mixed paste firmly into the repair area. Shape or fill as needed before it begins to set.
Cure: Allow 1 hour for initial set; leave for 12 hours for full cure strength.
Finish: Use files, sandpaper, or other tools to smooth and finish the cured surface to the desired finish.
