655-K G/flex Repair Kit

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.

Epoxy Facts

Choosing Your Epoxy

Selecting the right epoxy system can feel overwhelming. This Epoxy System Selection Guide helps highlight the differences between the systems so you can pick which system will work best for your project.

Surface Preparation

The fundamentals of surface preparation are important whether you are bonding, fairing or applying fabrics. The success of the epoxy application depends not only on the strength of the epoxy, but also on how well the epoxy adheres to the surface. Unless you are bonding to partially cured epoxy, the strength of the bond relies on the epoxy’s ability to mechanically “key” into the surface.
