MAS Low Viscosity Epoxy Resin is a blend of standard low molecular weight epoxy resin and reactive diluents. Formulations based on MAS Low Viscosity Epoxy Resin are typically cured at room temperatures using MAS hardener in a 2:1 mix ratio, resin: hardener. MAS Low Viscosity Epoxy Resin can be used in a wide variety of applications including moisture exclusive coatings, laminating, and bonding. When modified with MAS fillers mixed formula can be used as a filling and fairing compound. This resin boasts a 600 cps viscosity. The reduced viscosity of MAS Epoxy Resin provides for complete wet out of fiber reinforced fabrics and reduces the potential for voids and other imperfections. MAS Low Viscosity Epoxy Resin is formulated from 100% low molecular weight reactive solids (for excellent moisture exclusion), and displays less than 1% shrinkage when cured.

STORAGE LIFE: MAS Low Viscosity Epoxy Resin is specifically formulated for use and storage in adverse conditions. A non-crystalling formula allows the resin to remain clear and flow at very low temperatures. MAS Epoxy Resin will last a minimum of 12 months in a sealed container. Experience has shown the shelf life in most circumstances to exceed two years.

MAS Slow Hardener is a phenol-free, modified amine, epoxy resin hardener. When used in conjunction with MAS Epoxy Resin it provides high reactivity and an extended gel time which allows for controlled application periods. Special features exhibited by this product include blush free surfaces, good ultraviolet stability, smooth finishes in cured films, excellent osmotic resistance, and the ability to cure under high humidity. MAS Slow Hardener is intended for use with MAS Epoxy Resin and can be applied in a diverse range of conditions where increased working time is required. We highly recommend formulations of MAS Slow Hardener when large surfaces are to be coated or laminated. Slow formulation cure blush free and eliminate the need for time consuming wash downs during on-going laminations or repetitive build coats. The low viscosity of MAS Slow Hardener (200-250 poise) when mixed with MAS resin is ideal for fast wet-out of reinforcing fabrics.

MAS Fast Hardener may be added to the MAS Slow Hardener to speed up curing, however, blends exceeding 30% of MAS Fast Hardener may compromise the non-blushing characteristics of the MAS Slow Hardener. The 2:1 mix ratio, resin:hardener should be maintained, no matter what hardener or blend of hardeners are used.

STORAGE LIFE: A minimum of 12 months in a sealed container.
Caution: Not recommended for use below 65 degrees F unless cure time is available.

MAS Medium Hardener is a polyamine blend intended for moderate reactivity and resistance to amine blushing. Moderate pot life, gel, and thin film set times provide advantages when filleting and fairing. MAS Epoxy/Medium mixed with thickeners, gel and set quickly enough to avoid draining and sagging, while still allowing ample flow time for controlled application periods. We recommend this hardener when "overnight" sandibility is more important than continuous laminating and open time (as provided by MAS Slow Hardener) MAS Medium will also provide a beautifully smooth void free finish, with great resistance to milking out during application and fogging in critical clear coating applications. MAS Medium's cure speed may be adjusted by the addition of MAS Fast or MAS Slow to Medium hardener. The 2:1 mix ratio of resin:hardener should be maintained regardless of hardener blend.

STORAGE LIFE: A minimum of 12 months in a sealed container at ambient temperatures. Caution: You may find amine blush on the surfacce after cure. Wash it off with plain water, ONLY, and let dry thoroughly before recoating.

MAS Fast Hardener is a rapid ambient temperature hardener for use with MAS Epoxy Resin. Fast Hardener can be used as an accelerator for MAS Slow or Medium Hardeners when customized cure times are required. Appropriate applications of Fast formulas include hardware bonding, spot filling, and fairing. Additionally, the superior bonding strength of Fast formulas is ideal for high strength secondary bonding applications such as structural tabbing and repair laminations. The rapid cure time of Fast allows overnight curing in low temperature conditions. We do not recommend mixing more than 5 oz. of formula unless rapid application techniques are incorporated. Surfaces coated with Fast formula may blush and must be carefully prepared prior to recoating and bonding. An induction time of 1-2 minutes is recommended prior to application of formula. We have found the low viscosity of Fast allows for fast wet-out of the heavy reinforcing fabrics often used in repair applications. Slow Hardener may be added to retard the cure speed of the Fast when customized cure times are required. Always maintain a 2:1 ratio of resin:hardener.

STORAGE LIFE: A minimum of 12 months in a sealed container at ambient temperatures.
Caution: you may find amine blush on the surface after cure. Wash it off water, ONLY, and let dry thoroughly before recoating.

Introducing F.L.A.G. Resin

Filleting, Laminating and Gluing Resin

F.L.A.G. Resin is a "medium" body resin specifically designed to perform as an adhesive and structural laminating fou ndation. The medium viscosity allows for the incorporation of fillers when fairing putties, gluing slurries and filleting systems are required. F.L.A.G. is more reactive than our Low Viscosity Resin when mixed with Medium Hardener. This keeps fillets and fairing from slumping. F.L.A.G Resin is next day sandable when cured at 60 degrees F. and higher with Medium Hardener. F.L.A.G Resin may be used with all MAS Hardeners, however, for filled applications we recommend Medium Hardener.

Rapid Cure

Our ONLY 1:1 ratio epoxy adhesive -- This stuff is FAST!!

It’s great for quick repairs and bonding. Mix small amounts - no more than 1/2 oz. of each of the resin and hardener at a time. You’ll have 1-2 minutes to use it, and 5-10 minutes to set it. You can sand in 1 hour, and full cure is in 4-6 hours. Be Careful - this is FAST, PERMANENT, and WATERPROOF. Eight oz. and 16 oz. kits are great for keeping on board or at home in the tool kit. Useful for quick kayak and canoe repair. Permanent and waterproof repair when you’re on the move.

Waterproof - not just water resistant!

Mix Ratio: 1:1 Resin to Hardener
Pot Life: 1-2 minutes at 77°F or faster
Work Time: 1-5 minutes
Sandable: 1-2 hours
Full Cure - 4-6 hours
