Loctite® Epoxy Weld Bonding Compound is a two-part system consisting of an epoxy resin and a hardener.

When mixed in equal volumes, the resin and hardener react to quickly produce a tough, rigid, high strength bond. Loctite® Epoxy Weld can be used as a convenient alternative to welding. It can be used as an adhesive for repairing, filling and rebuilding all metal and common surfaces. It cures to a metallic gray finish and can be easily sanded, drilled, machined or painted when fully cured. Loctite® Epoxy Weld does not shrink and is resistant to most shop fluids such as water, diesel fuel, gasoline, antifreeze, hydraulic fluid, motor oil and transmission fluids.

HOW TO USE:
Step 1: Safety Precautions

Avoid skin contact. Keep away from eyes. Avoid prolonged breathing of vapors. Apply in a well ventilated area. Open windows and doors to achieve good cross-ventilation. Wear safety glasses to protect eyes, and rubber or plastic gloves to protect skin.

Step 2: Preparation

Protect work area. Surfaces must be clean, dry and free from oil, wax and paint. For better adhesion, roughen smooth surfaces prior to cleaning. Pre-fit parts to be joined. Pierce tube nozzles using the reverse side of the caps. Squeeze out equal amounts of resin and hardener on a clean, disposable surface. Prepare only as much as can be used within 3 minutes of mixing. Recap tubes immediately after use. Match the black cap with the resin and the white cap with the hardener. Mix resin and hardener together for approximately 1 minute or until it is uniform in color.

Step 3: Application

Apply to surfaces to be filled or bonded. Join and press parts together. When bonding butt joints, adhesive should be applied as a reinforcing fillet or splint over the joint for additional support. Remove any excess glue immediately with acetone, mineral spirits or rubbing alcohol. Support until bond sets in 10 to 15 minutes at room temperature. Parts can be handled within 15 minutes and machined within 16 to 24 hours. Cure time is lengthened in cooler temperatures and shortened in warmer weather.

Step 4: Cleanup

Clean excess glue immediately with acetone before adhesive sets. Cured adhesive may be cut away with caution using a sharp blade. Prolonged immersion in paint stripper will soften the cured adhesive to aid removal.
