West System G/flex Epoxy - 650-8

West System G/flex is a tough, resilient epoxy engineered for a superior grip to metals, plastics, glass, masonry, fiberglass, and wet and difficult-to bond woods. G/flex is easy to use with a simple 1:1 mix ratio. It has a long open working time of 45 minutes at room temperature. G/flex reaches a working cure in 7-10 hours and a full cure in 24 hours.

Features:

• Toughness and Flexibility G/flex has been toughened. This gives G/flex the ability to make structural bonds that can absorb the stresses of expansion, contraction, shock, and vibration. G/flex is resilient and impact resistant. With a modulus of elasticity of 150,000 psi (WEST SYSTEM 105 Resin/205 Hardener has a modulus of elasticity of 450,000 psi), G/flex is more flexible and can deflect further than WEST SYSTEM 105/205, while being much stiffer than typical adhesive sealants.
• Bonds to wet and damp surfaces G/flex has the ability to glue damp woods. It can be used on wet surfaces, even underwater when applied with specific techniques.
• Excellent adhesion to hard-to-bond woods G/flex adheres tenaciously to difficult-to-glue hardwoods, both tropical and domestic varieties. This is important since many of the exotic and tropical species now being used to replace traditional woods present bonding challenges.
• Bonds well to a variety of materials G/flex is ideal for bonding a variety of materials, including dissimilar ones. G/flex has a superior grip so that it can be used to bond to metals, plastics, glass, masonry, and fiberglass. G/flex is ideal for repairs to aluminum boats and polyethylene and ABS canoes and kayaks. It can also be used to wet out and bond fiberglass tapes and fabrics.
• Ease of use G/flex is a simple two-part epoxy system. Resin and hardener are mixed in a 1:1 mix ratio by volume. For added convenience, a pre-thickened version, G/flex 655 Thickened Epoxy Adhesive, is also available. G/flex provides a relatively long open working time of 45 minutes. It cures in 7-10 hours and can be used in cool temperatures. Because it is simple to mix and use, G/flex is an excellent starting point for customers new to epoxy use.
• Versatility G/flex can be modified with WEST SYSTEM fillers and additives if you need to meet particular bonding needs. Adding G/flex to other WEST SYSTEM epoxies can improve their toughness and flexibility.

Note: Two 4 oz. bottles of liquid epoxy (one 4 oz. resin and one 4 oz. hardener) in a plastic bag.
