G/flex 655 epoxy resin adhesive - Transparent - 4L - West System

G/flex epoxy adhesive is a toughened, versatile 2 - part waterproof permanent bonding epoxy for bonding fiberglass, ceramics, metals, wet and hard - to - bond woods. With a modulus of elasticity of 150,000 PSI, G/flex 650 is slightly more flexible than standard epoxies and polyesters, but much stiffer than adhesive sealants. This gives G/flex 655 the ability to make structural bonds that can absorb the stresses of expansion, contraction, shock and vibration. It is ideal for bonding dissimilar materials. Mixed at a 1:1 ratio, G/flex 655 gives you 46 minutes of pot life and 60 - 75 minutes of working time at 72°F. It achieves an initial cure in 7 to 10 hours and a full cure in 24 hours.
