Loctite® Epoxy Marine

Features and Benefits

Loctite Epoxy Marine is a two-part system consisting of an epoxy resin and a hardener. The convenient syringe dispenses equal amounts of each component every time. When mixed in equal volumes, the resin and hardener react to produce a tough, rigid, high strength bond in 120 minutes. It can be applied and cured underwater. Ideal for repairing pipes. It cures to a white finish and can be easily sanded or machined. It does not shrink and is resistant to water and most common solvents.

Step 1: Safety Precautions

Well-ventilated area, gloves.

Step 2: Preparation

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. Remove the plug from between the piston. Cut off the end tips of the syringe. Depress the double piston to dispense equal parts of the two materials on a discardable surface. Mix resin and hardener thoroughly until uniform in color. Wipe syringe tips clean, retract piston slightly and close with the plug. Ensure that the plug is always placed in the same orientation on the tips.

Step 3: Application

Apply a small amount to both surfaces and assemble parts together. Remove any excess glue immediately with acetone. Support parts until bond sets in 120 minutes at room temperature. Allow full cure of 24 hours before subjecting to normal use.

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.
