Highly trusted by boat-builders, WEST SYSTEM Epoxy is ideal for use as an ultra-tough waterproof coating, a high-strength, gap-filling adhesive or an easily sanded surface filler. The Resin works in conjunction with a variety of WEST SYSTEM Hardeners, Fillers and Pumps for a wide range of applications.

Combined with 205 Fast, 206 Slow and 209 Extra-Slow Hardeners, the cure time of 105 can be fine-tuned and adjusted for a wide range of temperatures. For coating and roller applications, it can be combined with 207 Coating Hardener, which provides excellent thin-film characteristics to flow out and self-level without "fisheyeing." Cures clear to light amber, so you can achieve a natural wood finish when coating with varnish.
