MAS Fast Hardener is a rapid ambient temperature hardener for use with MAS Epoxy Resin. Fast Hardener can be used as an accelerator for MAS Slow or Medium Hardeners when customized cure times are required. Appropriate applications of Fast formulas include hardware bonding, spot filling, and fairing. Additionally, the superior bonding strength of Fast formulas is ideal for high strength secondary bonding applications such as structural tabbing and repair laminations. The rapid cure time of Fast allows overnight curing in low temperature conditions. We do not recommend mixing more than 5 oz. of formula unless rapid application techniques are incorporated. Surfaces coated must be carefully prepared prior to recoating and bonding. An induction time of 1-2 minutes is recommended prior to application of formula. We have found the low viscosity of Fast allows for fast wet-out of the heavy reinforcing fabrics often used in repair applications. Slow Hardener may be added to retard the cure speed of the Fast when customized cure times are required. Always maintain a 2:1 ratio of resin:hardener.
