Loctite PC 3965 Epoxy Repair Compound Overview

Loctite PC 3965 is a two-part, steel-filled epoxy repair compound designed for fast, cost-effective repairs to ferrous and non-ferrous materials. This metallic gray, non-sag paste cures quickly, hardens in 10 minutes, and bonds to steel, cast iron, stainless steel, concrete, copper, aluminum, and clean or abraded bronze. Once cured, it can be machined, drilled, tapped, or filed, making it ideal for emergency repairs with minimal downtime.
