105 Epoxy Resin is the base material on which all WEST SYSTEM 105 System epoxy compounds are built. The resin is a clear, pale yellow, low-viscosity liquid epoxy resin that cures to a hard, solid plastic with superior physical properties. 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 Epoxy Resin is formulated without volatile solvents and does not shrink after curing. It has a relatively high flash point and no strong solvent odor, making it safer to work with than polyester or vinylester resins. Resin viscosity is approximately 1000 centipoise (cp) at 72 F (22C).
105 Epoxy Resin is designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals when mixed at the proper ratio with a WEST SYSTEM Epoxy hardener. An excellent adhesive, 105 epoxy 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 without “fisheyeing.” 105 Epoxy Resin/207 Special Clear Hardener mixtures cure clear so you can achieve a natural finish when coating with varnish.
