Product Description
LOCTITE PC 3965 is a two-part steel-filled epoxy repair adhesive supplied as a 50 mL dual-cartridge system with resin and hardener. The mix ratio is 1:1 by volume or 100:73 by weight, with a 3 to 4 minute working life and 4 to 6 minute gel time at 25 deg C. It is a non-sag paste for overhead and vertical repairs and hardens in 10 minutes. After cure, it can be machined, drilled, tapped, or filed. Supported substrates include steel, cast iron, stainless steel, concrete, copper, aluminum, and clean abraded bronze.
Key features
- Equal-Ratio Volume Mixing: Resin and hardener mix 1:1 by volume; the weight ratio is 100:73.
- 3 to 4 Minute Working Life: Working life is 3 to 4 minutes at 25 deg C; gel time is 4 to 6 minutes.
- 23.9 N/mm^2 Steel Lap Shear: Typical lap shear strength is 23.9 N/mm^2 by ISO 4587 on grit-blasted mild steel.
Applications
Repair and bonding of steel, cast iron, stainless steel, concrete, copper, aluminum, and clean abraded bronze.
