G/flex Thickened Epoxy syringe

Great on plastics including HDPE, LDPE, ABS, PVC, Polycarbonate, and Hypalon.
Easy-to-use syringe to dispense small quantities of epoxy
Viscosity similar to gel toothpaste—won’t run or sag

G/flex 655 is a toughened epoxy that makes permanent, waterproof structural bonds. It absorbs the stresses of expansion, contraction, shock, and vibration. G/flex adheres tenaciously to HDPE, LDPE ABS, PVC, Polycarbonate, and Hypalon plastics. It also bonds metal, glass, masonry, fiberglass, and wood. The G/flex 655-1 syringe contains 0.42 oz of resin and 0.42 oz of hardener, perfect for small repair jobs.

WEST SYSTEM Specialty Epoxies


Six10 Thickened Epoxy Adhesive Six10 Thickened Epoxy Adhesive is a two-part epoxy with a consistency similar to gel toothpaste. We manufacture it under vacuum to prevent entrapped air bubbles. Our in-house chemists formulated this toughened system with 8% elongation. Conveniently, Six10 requires no hand mixing when used with a standard caulk gun and the static mixing wand that comes with each cartridge (pictured caulk gun not included). The self-metering coaxial cartridge dispenses a gap-filling, structural adhesive that bonds tenaciously to wood, metals, fiberglass, and concrete. Six10 has a working time of over 40 minutes until the mixing wand becomes unusable. This adhesive has shear thinning properties, which means it moves more like a liquid when you work the material. This allows its use in cooler temperatures. You can also use it to wet out lightweight fiberglass cloth. It will cure in temperatures as low as 50°F (10°C).	G/flex Epoxies G/flex is a two-part, toughened epoxy that can make structural bonds which absorb the stress of expansion, contraction, shock, and vibration. We formulated this system for high elongation with an ultimate elongation of around 30%. The increase in elongation and lower modulus (stiffness) that it provides equates to better adhesion to substrates. This helps it resist a peel or delamination from starting. G/flex has a 1:1 mix ratio by volume for easy measuring. It’s also ideal for bonding dissimilar materials. We offer it in two versions. The liquid version, G/flex 650, has a consistency similar to honey. You can thicken it with 406 Colloidal Silica to reach the same viscosity as the 655. The pre-thickened version, G/flex 655, has a consistency like gel toothpaste. With proper application techniques, it will bond to wet/damp substrates and dense or oily woods like teak and oak.	G/5 Five-Minute Adhesive G/5 Five-Minute Adhesive is a two-part adhesive that will cure to a gel state within minutes. It has a 1:1 mix ratio by volume. You can wet sand it about 30 minutes after application. It is ideal for a temporary, quick cure that’s convenient for some applications like fabricating a quick custom sanding block with some scrap fiberglass cloth and a piece of foam. G/5 should not be used where high loads are expected or if it will be continually immersed in water.
