Thickened G/flex Epoxy Adhesive, 4.5 oz. tubes of resin and hardener, plus instructions and application supplies. Tough bond on many different materials. Waterproof, flexible, permanent.The 655-K kit contains 4.5 oz. each of thickened G/flex 655 resin and hardener. Mixing ratio is 1:1. It also includes two reusable mixing sticks/applicators, one pair disposable gloves, four alcohol cleaning pads, 10 mixing palettes and complete handling and repair instructions. Mixed G/flex 655 is of a 'gel-toothpaste' consistency. It's still very spreadable, but stays put where it is applied. It makes structural bonds that can absorb the stresses of expansion, contraction, shock and vibration. In addition to its superior bonding to many different materials and its ability to bond dissimilar materials, Cured G/flex is much more flexible than other epoxies. This is an excellent property for boat building and repair. Polyethylene (HDPE) is a common kayak and canoe material. Its molecular structure resists gluing by most adhesives. G/flex solves the problem; it bonds well to polyethylene and ABS plastics. At 72 degrees F pot life is 45 minutes. Working time is 75 minutes. It cures to a solid in three hours and cures to its full strength in one to two days. It cures faster in warmer temperatures and slower in colder ones. Clean up is simple. Wipe up spills with absorbent materials. Clean residue before it cures, with alcohol or acetone. It has the ability to glue damp woods. It can be used on wet surfaces, even underwater when applied with specific techniques.
