Mas Epoxies Epoxy Resin is non-blushing, has low viscosity, and low odor. Low-Vis resin is a superior blend of low molecular weight epoxy resin and reactive diluters, designed to produce an easy-flowing reliable system with low drip and no blush. Can be used in a huge variety of applications, including boat hulls and structures which need to completely exclude moisture, as well as laminating and bonding of nearly all materials. When modified with MAS fillers such as wood powder or Colloidal Silica, the resin can be used as a filling and fairing compound with outstanding results. This resin boasts a 600 cps viscosity for smooth, easy wet-out of fiberglass laminations. The reduced viscosity also provides for complete wet-out of fiber-reinforced fabrics and reduces the potential for voids and other imperfections.
