West System products are formulated to provide maximum physical properties while being easy to use. West System epoxies are versatile. With the 105 System, users can blend resins, hardeners, fillers and additives to get the right combination for their project’s requirements. 105 Resin is paired with one of four hardeners depending on the user’s needs for working time and coating clarity. Fillers and additives allow further adjustments to the mixture’s handling characteristics and cured physical properties. Allowing the user to tailor the epoxy to their exact needs for boat construction, boat repair, and a wide array of other uses is what West System has always been about.
