MAS Epoxies 2:1 Premium Marine Non-Blushing Medium Hardener

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

Features:

• 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
• Compatible with MAS Epoxies Pump Set for Resins & Hardeners (30-016)
