MAS Epoxy medium hardener is a polyamine blend intended for moderate activity and resistance to blushing. Moderate pot life gel and thin film set times provide advantages when filleting and fairing.

MAS Epoxy Medium mixes with thickeners, gel and sets quickly enough to avoid draining and sagging, while still allowing ample flow time for controlled application periods.

This hardener is a good choice when overnight sandability is more important than continuous laminating and open time. Won't 'milk out' during application or fog up in critical clear coating applications.

Available in Pint, Quart, Half Gallon, Gallon, 4 Gallon, and 5 Gallon sizes.
