West System 105 Epoxy Resin

105 Resin is the base material of the WEST SYSTEM family of products, on which all of the WEST SYSTEM compounds are built. The resin is a clear, pale yellow, low-viscosity liquid epoxy resin. Formulated for use with WEST SYSTEM hardeners, it can be cured in a wide temperature range to form a high-strength solid with excellent moisture resistance.

It is designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals. An excellent adhesive, 105 will bridge gaps and fill voids when modified with WEST SYSTEM fillers and can be sanded and shaped when cured.

With roller applications, it has excellent thin-film characteristics to flow out and self-level without "fisheyeing." The resin cures clear so that you can achieve a natural finish when coating with varnish. It has a relatively high flash point and no strong solvent odor, making it safer to work with than polyesters. Resin viscosity is approximately 1000 cP (centipoise) at 72°F (22°C). 

WEST SYSTEM epoxy resin and hardeners are packaged in three "Group Sizes." For each container size of resin, there is a corresponding sized container of hardener. When purchasing resin and hardener, be sure all containers are labeled with the same Group Size letter (A, B or C).

WEST SYSTEM Epoxy cures to a high-strength plastic solid at room temperatures, by mixing specific proportions of liquid epoxy resin and hardener. By using a simple "cookbook" approach you can tailor the handling characteristics and the physical properties of the cured epoxy to suit your working conditions and specific coating or bonding application.

1. Start with 105 Resin, the basic ingredient of epoxy compounds.
2. Mix with one of the Hardeners.
   West System 205 Epoxy Fast Hardener
   West System 206 Epoxy Slow Hardener
   Select a hardener for its intended use and for the cure speed best suited for your job in the temperature range in which you are working.
3. Add one of six  fillers to thicken the mixture as needed. Select a filler for its handling characteristics or cured physical properties. Or, add one of six  additives to provide specific coating properties.
