West System 105 Epoxy

105 Resin is the base material of the West System family of products, on which all compounds are built. The resin is a clear, 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, the 105 will fill gaps and bridge voids when modified with West System fillers and can be sanded and shaped when cured. With roller applications, it possesses excellent thin-film characteristics to flow out and self-level with out "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 cps at 72F.

West System Hardeners

• West System Hardeners yield a rigid moisture-resistant solid with great bonding and coating properties.
• Mixed with #105 resin in a 5:1 ratio, choose either the #205 Fast Hardener for 9-12min. pot life at 72 degrees F or the #206 Slow Hardener for extended 20-25min. pot life (min. 60 degrees F temperature)
• Mini Pump Kit is a must for precise metering of all group sizes of WEST SYSTEM resins and hardeners

Hardener selection—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.

205 Fast Hardener

205 Fast Hardener is a medium-viscosity epoxy curing agent. It is used in a majority of situations, at lower temperatures and to produce a rapid cure that develops its physical properties quickly at room temperature. When mixed with the 105 Resin in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties. Not intended for clear coating.

206 Slow Hardener

206 Slow Hardener is a low-viscosity epoxy curing agent for use when extended working and cure time is needed or to provide adequate working time at higher temperatures. When combined with 105 Resin in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties. Not intended for clear coating.
