West Systems 655 G-Flex Epoxy Adhesive Repair Kit

WEST SYSTEM® G/flex® 655 Epoxy Adhesive is a pre-thickened, high-strength marine epoxy designed for strong, reliable bonding in demanding conditions. Developed to be easy to use while delivering exceptional toughness, G/flex 655 is ideal for structural repairs where flexibility and gap-filling are essential.

Unlike standard liquid epoxies, G/flex 655 is supplied in a thickened, non-sag consistency, making it perfect for vertical surfaces, filleting and applications where the adhesive needs to stay in place. It creates a durable, waterproof bond capable of absorbing shock, vibration and movement without cracking or failing.
