Mas Slow No Blush Hardener - Quart (Slow No Blush Catalyst)

Mas Slow Hardener is a phenol-free, modified amine, epoxy resin hardener. When used in conjunction with MAS Epoxy Resin it provides high reactivity and an extended gel time, which allows for controlled application periods. 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. 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. A formulation of MAS Epoxy and MAS Slow Hardener is highly recommended when large surfaces are to be coated or laminated. Slow formulations cure blush free and eliminate the need for time consuming wash downs during on-going laminations or repetitive build coats. The low viscosity of MAS Slow Hardener when mixed with MAS resin is ideal for fast wet-out of reinforcing fabrics.
