Using the best epoxy for the job can make the difference between a high-quality finished product and a complete do-over. A toughened, 2-part epoxy with a 1-to-1 mix ratio, WEST SYSTEM® G/flex epoxy is more flexible than standard epoxies and much stronger than typical caulking or adhesive sealants.
G/flex is a waterproof epoxy available as a liquid and a pre-thickened adhesive. This advanced formula is resilient enough to absorb the stress of expansion, contraction, shock and vibration. It repairs leaks in aluminum boats and adheres well to polyethylene and ABS watercraft. G/flex offers a superior grip to aluminum and other metals, plastics, fiberglass, ceramic, masonry, glass, damp wood, difficult-to-bond wood species and dissimilar materials.
The liquid epoxy can be used as a coating or modified with WEST SYSTEM fillers and additives and used to wet-out fiberglass tapes and fabrics. Its working time is 45 minutes at room temperature, it reaches an initial cure in 7-10 hours and a full cure in 24 hours. The pre-thickened version will even cure underwater.
WEST SYSTEM Brand 650-8 G/flex Epoxy is offered in a variety of package sizes, from 4 oz bottles to 50-gallon drums.
