MAS Epoxy Low Viscosity Resin has a superior blend of low molecular weight epoxy resin and reactive dilutents, for an easy-flowing, non-blushing system.

Use for barrier coatings, laminating, and bonding. Low viscosity epoxy provides complete wet out of fiber-reinforced fabrics, reducing the potential for voids and other imperfections. Modify with fillers such as wood powder or colloidal silica for filling and fairing compound applications.

MAS epoxy is typically used at room temperatures using your choice of hardener (MAS recommends their Fast, Medium or Slow hardeners) in a 2 parts resin to 1 part hardener ratio. This versatile resin system can be used in a wide variety of applications, including boat hulls and structures, as well as laminating and bonding of nearly all materials.

Available in Quart, Half Gallon, Gallon, 4 Gallon, and larger sizes.

Info & Guides

Amine blush is a waxy layer that forms during the cure process of most epoxy resins. No blush is critical if you intend to apply additional epoxy or varnish over it. MAS epoxy won't blush as long as it is applied in anything under 98% humidity.

Simple to Use Epoxy - Jamestown had best price

By PaulW from Caldwell, ID

I was looking for more epoxy for my CLC Teardrop kit build. Jamestown had the best price I could find, when shipping was factored in. This stuff works well. Easy to measure with the pumps.

Bottom Line Yes, I would recommend to a friend

Excellent for wooden boats

By Johnny from tennessee

I've used MAS epoxy on 4 wood strip kayaks and numerous other projects and have been completely satisfied. I've stopped using the fast hardener as it gels pretty fast in hot weather, but that is what it is supposed to do. Overall no complaints.

Bottom Line Yes, I would recommend to a friend

Works as advertised

By Tim from Northfield, Minnesota

Verified Purchase

I used it to fill some small gaps in an endgrain cutting board I made. I was concerned that the overflow might penetrate the wood near where I applied it, but it didn't, The excess sanded away easily after hardening without leaving a stain or shadow. I will probably buy some higher viscosity resin to fill in larger gaps. I would like to learn a way to mix very small amounts to do small touchups.

Bottom Line Yes, I would recommend to a friend

This is the absolute best fiberglass resin and hardener.

By Bob. from Chesapeake Bay.

Verified Purchase

No blush means that you do not have to do any prep between applications. Nothing could be easier. You can also mix the hardeners, fast, medium, or slow to manage any working time or setup you need. The low viscosity resin is perfect for penetrating any glass material and penetrating water damaged wood base. I will never use West products. MAS is far superior.
