EPOXY REPAIR PASTE PC-7

PC-7 Epoxy Repair Paste

PC-7 Epoxy Repair Paste is a heavy-duty, two-part epoxy designed for permanent repairs in demanding workshop and restoration environments. This thick, paste-grade epoxy fills, bonds and rebuilds damaged areas with exceptional strength and durability.

With a simple 1:1 mix ratio, PC-7 is easy to measure and apply. Once cured, it can be drilled, tapped, sanded, filed and machined — making it ideal for automotive restoration, fabrication and general workshop repairs.

If it’s cracked, worn, corroded or broken, PC-7 helps you fix it properly.

Application Guidelines

1. Ensure surfaces are clean, dry and free from grease, oil and loose rust.

2. Abrade smooth surfaces to create a mechanical key.

3. Mix equal parts of resin and hardener thoroughly until colour is uniform.

4. Apply firmly into the repair area, pressing into cracks and voids.

5. Allow to cure fully before sanding, drilling or machining.

Cure time varies depending on temperature. Warmer conditions accelerate curing.
