G/FLEX 650 TOUGHENED EPOXY - PART A - 125ML

WEST SYSTEM G/flex 650 is a toughened, slightly flexible liquid epoxy, made under licence in Australia by ATL Composites. It creates permanent, waterproof bonds that can absorb shock, vibration, expansion and contraction, so it is ideal for joining dissimilar materials and for repairs on parts that flex in use. It is thick enough to stay in a joint without draining out.

Bonds to

• Aluminium and other metals
• Fibreglass and composites
• Plastics, including polyethylene and ABS kayaks and canoes
• Damp, oily and hard-to-glue timbers
• Glass, ceramics and masonry

Typical uses

• Aluminium boat repairs and sealing leaks

• Timber boat, household and sporting equipment repairs
• Wetting out fibreglass tape and cloth for reinforced repairs
• Can be thickened with WEST SYSTEM fillers and additives for gap filling and fillets
