Full product details, applications & manufacturer specifications
G/flex 650 Toughened Epoxy G/flex® 650 is a toughened, versatile, liquid epoxy for permanent waterproof bonding of fibreglass, ceramics, metals, plastics, and damp and difficult-to-bond woods.
It is a bit more flexible than standard epoxies and polyester but much stiffer than adhesive sealants. This gives it 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 fibreglass tapes and fabrics.
This system is simple to use with its 1:1 mix ratio by volume. G/flex 650 Toughened Epoxy Adhesive is designed to bond to: Plastics Metals Glass Masonry Fibreglass Modify With Fillers.
