PRO-SET Assembly Adhesives Part A and Part B

PRO-SET Expanding Epoxy Foam – Part A & Part B

PRO-SET Expanding Epoxy Foam is a two-part, pre-thickened epoxy system designed for lightweight structural filling, buoyancy and core replacement in demanding composite applications. When Parts A and B are mixed, the system expands and cures to a strong, closed-cell foam that bonds tenaciously to wood, fiberglass, carbon fiber, metals and many other substrates.

Engineered for professional builders, this expanding epoxy foam is ideal for secondary bonding, void filling, edge reinforcement and buoyancy modules in marine, transportation, architectural and industrial projects. Its excellent adhesion and moisture resistance make it a smart choice wherever weight savings and toughness are both critical.
