WEST SYSTEM® epoxy resin cures to a high-strength plastic solid at room temperatures, by mixing specific proportions of liquid epoxy resin and hardener.  This highly moisture-resistant plastic adheres to a wide range of materials, making it ideal for projects that require water and chemical resistance, and strong physical properties for structural bonding.  Select from a range of hardeners that allow you to tailor the mixture to suit your working conditions and specific application.

105 Resin

WEST SYSTEM 105 Resin is a low viscosity, solvent free liquid marine 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.

105 is designed specifically to wet -out and bond with wood-fiber, fiberglass, reinforcing fabrics and a variety of metals when mixed at the correct ratio with a WEST SYSTEM hardener.

An excellent epoxy adhesive, 105 mixtures 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.

205 Fast Hardener

205 Fast Hardener is used, in the majority of situations, at lower temperatures to produce a rapid cure that develops its physical properties quickly at room temperature.

Cured resin and hardener 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 used when extended working and cure time is needed, or to provide adequate working time at higher temperatures.

Cured resin and hardener yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties.  Not intended for clear coating.

207 Special Clear Hardener 

207 Special Clear Hardener has been specially developed for coating applications where an exceptionally clear, moisture resistant, natural wood finish is desired.

105/207 mixtures resist clouding in  humid conditions and exhibit extremely low blush formation - as low as any epoxy, including so-called "no-blush" epoxies.

105/207 has strong physical properties, so it can be used as a structural adhesive for gluing and laminating. It has excellent compatibility with paints and provides a beautiful, long lasting finish when used with quality UV-filtering varnish.

209 Super Slow Hardener

209 Super Slow / Tropical Hardener is formulated for general coating and bonding applications in extremely warm and/or humid conditions, or when extended working time is desired at room temperature. Not intended for clear coating.
