MAS Slow hardener is formulated for use with MAS epoxy resins and can be applied in a wide range of conditions where increased working time is required.

We highly recommend MAS Slow Hardener when coating or laminating large surfaces. The Slow formulation cures blush free and eliminates the need for time consuming wash downs during on-going laminations or repetitive build coats.

Use this hardener (200-250 poise) with MAS low viscosity epoxy resin for fast wet-out of reinforcing fabrics.
