![]() ![]() MAS Fast Hardener may be added to the MAS Slow Hardener to speed up curing. The low viscosity of MAS Slow Hardener (200-250 poise) when mixed with MAS resin is ideal for fast wet-out of reinforcing fabrics. Slow formulation cures blush free and eliminates the need for time consuming wash downs during on-going laminations and repetitive build coats. We highly recommend formulations of MAS Slow Hardener when large surfaces are to be coated or laminated. MAS Slow Hardener is intended for use with MAS Epoxy Resin and can be applied in a diverse range of conditions where increased working time is required. Special features exhibited by this product include blush free surfaces, good ultraviolet stability, smooth finishes in cured films, excellent osmotic resistance, and the ability to cure under high humidity. When used in conjunction with MAS Epoxy Resin it provides high reactivity and an extended gel time which allows for controlled and extended application periods. MAS Slow Hardener is a highly-regarded epoxy resin hardener that's phenol-free with modified amines. MAS Low Viscosity Epoxy Resin is formulated from 100% low molecular weight reactive solids (for excellent moisture exclusion), and displays less than 1% shrinkage when cured. ![]() The reduced viscosity of MAS Low Viscosity Epoxy Resin provides for complete wet out of fiber reinforced fabrics and reduces the potential for voids and other imperfections. This resin boasts a 600 cps viscosity for smooth, easy wet-out of fiberglass lamination. When modified with MAS fillers such as wood flower or colloidal silica the resin can be used as a filling and fairing compound with outstanding results. MAS Low Viscosity Epoxy Resin can be used in a wide variety of applications including boat hulls and structures which need to completely exclude moisture, as well as laminating and bonding of nearly all materials. MAS Low Viscosity Epoxy Resin is typically used at room temperatures using your choice of MAS hardeners (Fast, Medium and Slow) in a 2:1 mix ratio (resin:hardener). It also goes further since a gallon of resin is actually 1.5 gallons of mixed resin with hardener. This is our resin of choice, over other brands, in our shop when looking for the best results on wooden boat hulls. This resin system is a SUPERIOR blend of low molecular weight epoxy resin and reactive dilutents, designed to produce a clear easy-flowing reliable system with low drip and no blush. MAS Low-Viscosity Resin is non-blushing, very clear, low viscosity, low odor and has easy mixing ratio's.
