105A Epoxy Resin

105 Epoxy 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. 105 Resin is formulated without volatile solvents and does not shrink after curing. It has a relatively high flash point and no strong solvent odour, making it safer to work with than polyester or vinylester resins.

105 Resin is designed specifically to wet out and bond with wood fibre, fibreglass, reinforcing fabrics and a variety of metals when mixed at the proper ratio with a West System hardener. An excellent adhesive, 105 mixtures will bridge gaps and fill voids when modified with West System fillers and can be sanded and shaped when cured.

205A 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.
