Product Description
West System 655-2QT G/Flex Epoxy Adhesive, 2 Quarts | Toughened & Flexible
- Toughened epoxy resin and hardener system – WEST SYSTEMG/flex 655 is a thickened, two-part epoxy resin kit that's Made in the USA and designed for permanent, waterproof structural bonding where durability and controlled flexibility are required.
- Excellent adhesion to difficult materials – WEST SYSTEM epoxy bonds tenaciously to fiberglass, metals, ceramics, many plastics, and hard-to-bond woods, including tropical and domestic hardwood species.
- Flexible strength with defined stiffness – More flexible than standard epoxy resins or polyester, yet stiffer than adhesive sealants. G/flex forms structural bonds with a modulus of elasticity of 150,000 PSI to absorb shock and vibration.
- 1:1 mix ratio with extended working time – Mixed 1:1 by volume, this epoxy resin and hardener provides 46 minutes pot life at 72°F and 60 to 75 minutes open working time for alignment and assembly.
- Reliable cure in marine and cold conditions – Initial cure in 3 to 4 hours, workable cure in 7 to 10 hours, and full cure in 24 hours. Suitable for marine epoxy repairs, cold weather epoxy use, and bonding damp or wet surfaces.
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 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 gives you 45 minutes of working time at room temperature. It reaches an initial cure in 7 to 10 hrs and full cure in 24 hrs.
