The 105 Epoxy Resin is the base material of the WEST SYSTEM family. A clear, pale yellow, low-viscosity resin, 105 forms a high-strength solid with excellent moisture resistance, and is designed specifically for wood fiber, fiberglass, reinforcing fabrics and a variety of metals. 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 (sold separately), 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.
