Product Overview

Toughened, versatile, liquid epoxy resin for permanent  bonding of fiberglass, ceramics, metals, plastics, damp and difficult-to-bond woods.

G/flex 650 is a bit more flexible than standard epoxies and polyester, but much stiffer than adhesive sealants. This gives G/flex 650 the ability to make structural bonds that can absorb the stress of expansion, contraction, shock and vibration. It is ideal for bonding dissimilar materials. It can be modified with WEST SYSTEM fillers and additives, and used to wet-out fiberglass tapes and fabrics. Mixed at a 1:1 ratio, G/flex 650 gives you 45 minutes of working time at 72°F. It reaches an initial cure in 7 to 10 hours and full cure in 24 hours. 650 G/flex Resins should be paired with comparable size 650 G/flex Hardeners.
