The heart of the WEST SYSTEM family of products. A clear, light amber, low-viscosity liquid epoxy resin formulated specifically to wet out and bond with wood, fiberglass and a variety of metals. With roller application, it possesses excellent thin-film characteristics in flowing out and self-leveling without fish-eyeing. Cures quite clear in a wide temperature range and can be sanded and shaped afterwards. Works as an excellent adhesive when mixed with WEST SYSTEM fillers to reduce sag and bridge voids. We strongly recommend the use of WEST SYSTEM dispenser pumps (SKU 3405669).
