G/flex is a product of West System, a division of Gougeon Brother's, Inc. The Gougeon brothers have been using epoxy resins in boat building and repair for some 50 years.
It makes structural bonds that can absorb the stresses of expansion, contraction, shock and vibration.
G/flex works very well to bond hypalon to hypalon or wood.
In addition to its superior bonding to many different materials and its ability to bond dissimilar materials, G/flex is much more flexible than other epoxies. This is an excellent property for boat building and repair.
Polyethylene (HDPE) is a common kayak and canoe material. Its molecular structure resists gluing by most adhesives. G/flex solves the problem; it bonds well to polyethylene and ABS plastics.
Many boats are made from aluminum, G/flex works well for repair seams on aluminum boats and for adhering patches.
At 72 degrees F pot life is 45 minutes. Working time is 75 minutes. It cures to a solid in three hours and cures to its full strength in one to two days. It cures faster in warmer temperatures and slower in colder ones.
Clean up is simple. Wipe up spills with absorbent materials. Clean residue before it cures, with alcohol or acetone.
G/flex adheres tenaciously to difficult-to-glue hardwoods, both tropical and domestic varieties.
It has the ability to glue damp woods. It can be used on wet surfaces, even underwater when applied with specific techniques.
G/flex does indeed belong in every boater's repair kit. The more you use it, the more uses you'll find for it - with your boating gear and other sporting and household items. It's easy to mix and use. The instructions that come with the kit are top notch.
