Epoxy Medium Hardener Part Two Liquid 1 gal

A polyamine blend intended for moderate reactivity and resistance to amine blushing. Moderate pot life, gel, and thin film set times provide advantages when filleting and fairing. MAS epoxy/medium mixed with a thickener, gels and sets quickly enough to avoid draining and sagging while still allowing ample flow time for controlled application periods. This hardener is recommended when 'overnight' sandibility is more important than continuous laminating and open time (as provided by MAS slow hardener). This hardener will also provide a beautifully smooth, void free finish with great resistance to milking out during application and fogging in critical clear coating applications. MAS medium's cure speed may be adjusted by the addition of fast or slow hardeners. The 2:1 mix ratio of resin : hardener should be maintained, regardless of hardener blend.
