West System Junior Pack 500grm, (500grm 105 Resin) (100gr 205 Hardener)
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 all WEST SYSTEM epoxy compounds.
2. Mix with one of four WEST SYSTEM Hardeners. 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 WEST SYSTEM fillers to thicken the mixture as needed. Select a filler for its handling characteristics or cured physical properties. Or, add one of six WEST SYSTEM additives to provide specific coating properties.
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).
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.
