G/flex® Toughened Epoxies

G/flex Toughened Epoxies are used for the permanent waterproof bonding of fiberglass, ceramics, metals, plastics, damp and difficult-to-bond woods. With a modulus of elasticity of 150,000 PSI, they are a bit more flexible than standard epoxies and polyester, but much stiffer than adhesive sealants. This gives G/flex the ability to make structural bonds that can absorb the stress of expansion, contraction, shock, and vibration. G/flex is ideal for bonding dissimilar materials; it can be modified with WEST SYSTEM fillers and additives, and the G/flex 650 can be used to wet-out fiberglass tapes and fabrics.
WEST SYSTEM G/flex 650 is a toughened, versatile, liquid epoxy that readily coats and wets out substrates.
WEST SYSTEM G/flex 655 is a toughened, versatile epoxy that is conveniently pre-thickened to quickly build up thickness and will not run or sag. 
Mixed at a 1:1 ratio, G/flex gives you 45 minutes of working time at 72°F. It reaches an initial cure in 7 to 10 hrs and full cure in 24 hrs.
