West System Epoxy 655-1 Cartridge

For tough, permanent, waterproof repairs on plastics

G/flex 655 Epoxy Adhesive is the result of years of experimentation to develop a toughened epoxy that was simple to use and would adhere tenaciously to a variety of materials under difficult conditions.

G/flex 655 is, first of all, a high-strength epoxy—designed for permanent, waterproof, structural bonding. Furthermore, G/flex has a modulus of elasticity of 1.03 GPa, which gives G/flex the toughness to make structural bonds that can absorb the stresses of expansion, contraction, shock, and vibration.

G/flex adheres tenaciously to difficult-to-glue hardwoods, both tropical and domestic varieties—white oak, Ipe, teak, greenheart, purpleheart and black walnut to name a few. G/flex also has the ability to glue damp woods.

It can be used on wet surfaces, even underwater when applied with specific techniques.

G/flex is ideal for bonding a variety of other materials, including dissimilar ones—metals, plastics, glass, masonry, and fibreglass.
