MAS Medium Epoxy Hardener

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.

      Comments about MAS Medium Epoxy Hardener:

      The product is what it is......it is hardener and is messy but very effective. I am taking this survey because the customer service was outstanding!! The fellow (and i wish i could remember his name had a sense of humor which lightened the situation). If you have his name, thank him for an outstanding job!

        I'm now working on building my fourth boat using MAS epoxy. The two CLC kayaks from 2000 are still going strong and the Beachpea I just finished looks and sails great. I used the MAS on a set of 8' Pete Culler oars as well as using it to repair my 60 year old Thistle. I've never had an epoxy joint fail.
