    MAS Epoxies Medium Hardener is a polyamine blend intended for moderate reactivity and resistance to amine blushing.


    • Optimized for composite wet lay-up, hardware and secondary bonding, moisture-exclusive coating and surface fairing
    • Gels and sets quickly enough to avoid draining and sagging while still allowing ample flow time for controlled application periods
    • Especially useful when "overnight" sandability is more important than continuous laminating and open time
    • Moderate pot life, gel, and thin film set times provide advantages when fileting and fairing
    • Provides a smooth, void-free finish with great resistance to milking-out during application and fogging in critical clear-coating applications
    • Cure speed may be adjusted by the addition of MAS Fast or MAS Slow hardeners

    Handling characteristics:

    • Mix ratio: (2) parts resin : (1) part hardener
    • 15 Minute pot life
    • 3 Hour working time at 70° F
