## Overview

West System G/FLEX Epoxy QT Kit is a high-performance, toughened 2-part epoxy designed for permanent waterproof bonding of challenging materials including damp woods, metals, plastics, and fiberglass. With a 150,000 PSI modulus of elasticity, it offers superior flexibility and structural strength to absorb shocks and vibrations. Its 46-minute pot life and 60-75 minute working time provide ample precision, while its compatibility with fillers and additives allows customization for diverse repair and construction needs.

## Description

G/flex 650 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 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 fiberglass tapes and fabrics. Mixed at a 1:1 ratio, this 2-part epoxy gives you 46 minutes of pot life at 72°F and an open (working) time of 60-75 minutes. It reaches an initial cure in 3 to 4 hrs and a workable cure in 7-10 hours.
