G/flex 655 Thickened Epoxy Adhesive

G/flex® Thickened Epoxy Adhesive is a toughened, versatile, 2-part epoxy for permanent waterproof bonding of plastic, fiberglass, ceramics, metals, damp, and difficult-to-bond woods. G/flex 655 is a bit more flexible than standard epoxies and polyester but much stiffer than adhesive sealants. This gives G/flex 655 the ability to make structural bonds that can absorb the stress of expansion, contraction, shock, and vibration. It is ideal for bonding dissimilar materials. This system is simple to use with its 1:1 mix ratio by volume.

G/flex 655 Thickened Epoxy Adhesive is designed to bond to:

Plastics
Metals
Glass
Masonry
Fiberglass
Wet and difficult-to-bond woods

Project Uses:

Polyethylene & ABS Canoe/Kayak Repairs
General Bonding

G/flex 655 Thickened Epoxy quickly builds up thickness and will not run or sag. It’s also toughened to make structural bonds that absorb the stresses of expansion, contraction, shock and vibration.

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.

Home Repairs

WEST SYSTEM Epoxy has been used to reliably build and repair boats for over thirty-five years. But its practical uses are not limited to boats or the marine industry. The techniques used to restore an aging runabout, repair a delaminated fiberglass deck or build a stripper canoe are the same techniques used to restore historic buildings, repair damaged vehicles and build weatherproof outdoor furniture. If you’ve used epoxy on a boat repair or building project, it’s likely you’ve found other uses for it around your house or shop. We have put together a manual of some of the more common non-marine uses of epoxy.
