105 Resin is the base material of the West System family of products, on which all of the compounds are built. The resin is a clear, pale amber, 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 fill gaps and bridge voids when modified with West System filler and can be sanded and shaped when cured. With roller applications, it possesses 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.
