About this item
Product details
The West System G/Flex 650 2-Part Resin/Hardener Toughened Epoxy System (4oz) is a toughened, versatile, liquid epoxy for permanent waterproof bonding of fiberglass, ceramics, metals, plastics, damp and difficult-to-bond woods. With a modulus of elasticity of 150,000 PSI, it 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 hrs. and full cure in 24 hrs.
High-Strength Epoxy
G/flex 650 is, first of all, a high-strength epoxy designed for permanent, waterproof, structural bonding. Furthermore, G/flex has a modulus of elasticity of 150,000 psi, giving G/flex the toughness to make structural bonds that can absorb the stresses of expansion, contraction, shock and vibration. G/flex Epoxies are toughened resilient two-part epoxies.

A VERY TOUGH EPOXY at the best price I could find
This is the TOUGHEST epoxy I've ever found. After it's cured, you can literally hit it with a hammer and it won't crack, unlike many other epoxies. In my experience, it takes 24 hours to fully cure, but if you need a "thickened" epoxy, which Gougeon Brothers / West System also makes (G-Flex 655), you can just wait about 45 minutes after mixing before you apply it. This avoids having to keep both G-Flex 650 and G-Flex 655 on hand. This is the glue we always wished for as kids after we broke something.
Verified Purchase
As expected from West Systems, works well and not in huge dispensers. one note of caution - keep the inside caps seperated for re-use later and don't mix them up!

great product, fast shipping
Exactly what I needed. Used it to bond some spots on my skis and it worked great. Super fast shipping
