MAS Fast Hardener
The low viscosity of Fast Hardener allows for quick wet-out of the heavy reinforcing fabrics often used in repair applications. MAS Non-Blushing Fast Hardener is a room temperature rapid hardener for use with MAS Epoxy Resins. Fast Hardener can also be used as an accelerator for the MAS Slow or Medium Hardeners when customized cure times are required. Appropriate applications for Fast include: bonding hardware, 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 of 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. An induction time of 1-2 minutes is recommended prior to application of formula. Always maintain a 2:1 ratio of resin : hardener.
STORAGE LIFE: A minimum of 12 months in a sealed container at ambient temperatures.
Caution: you may find amine blush on the surface after cure. Wash it off water, ONLY, and let dry thoroughly before recoating.
