MAS Epoxies

Low Viscosity

Low Viscosity (LV) Epoxy Resin is the first resin in our MAS Epoxies 2:1 non-blushing system. It can be paired with three different hardeners and mixed with FLAG Resin so you can customize your epoxy to your unique needs.

FLAG Resin

FLAG Resin is a medium-bodied 2:1 non-blushing resin. It is compatible with LV resin and the Slow, Medium and Fast Hardeners, so you can create a custom epoxy that meets your needs.

Slow Hardener

Slow Hardener is a 2:1 non-blushing hardener. It can be paired with our LV Resin or FLAG Resin and mixed with the 2:1 Medium Hardener and/or Fast Hardener, making it one of the most versatile epoxy hardeners on the market. You get more time than with other supplier’s “Slow Hardeners” so it’s easier to work with in high temperatures and for beginners. Slow Hardener gives you strength, beauty and a four-hour working time.

Medium Hardener

Medium Hardener provides the non-blushing properties you’ve come to love from MAS products and will give you a 3 hour working time. Use it with LV or FLAG resin and remember you can mix and match it with the Slow or Fast Hardeners to create a custom viscosity and gel time.

5:1 Traditional

Marine Epoxy Traditional Resin can be used with three of our hardeners depending upon your application. Try the 520 Slow or 510 Fast hardeners for structural applications at a 5:1 by volume mix ratio. Or if you have completed your structural lamination use the 3:1 by volume 320 Clear hardener to achieve a beautiful clear coating.

Penetrating Epoxy

MAS Epoxies Penetrating Epoxy Sealer is solvent free (100% solids) so you know you are going to get penetrating power and a complete cure. It also means that our Penetrating Epoxy is VOC-Free, which brings our customers peace of mind. Epoxy resins like our Penetrating Epoxy System are ideal for repairs because of their strength and waterproofing characteristics.

Table Top Epoxy

If you want the appearance of 50 coats of varnish with just one pour, look no further than our Table Top Epoxy. This 1:1 epoxy system provides you with a protective glass-like finish on any surface. Table Top Epoxy goes on in thick pours that self-level. Everything about Table Top Epoxy makes it easy to get an alluring clear finish quickly and easily.

Rapid Cure

The Rapid Cure kit is probably the fastest curing epoxy you’ve ever seen. It’s great for quick household fixes, especially small items. Be sure to prepare the surfaces to be bonded before mixing the product as it will set in under 1 minute.

Aqua Zone

You can rest easy with Aqua Zone aboard your boat. This underwater-curing, emergency-repair putty is designed to help you get home safely in case something causes damage to your boat while you’re on the water. You can also use it to repair wooden or concrete pylons that need structural reinforcement below the waterline.


Gluzilla is a cartridge filled with the resin and hardener you need to complete gluing and filling jobs with ease. The resin, hardener and filler are dispensed from the tube in the exact ratio you need and mixed automatically with the static mixer attachment. Save yourself time and let us measure, fill and mix for you! We offer two sizes, the 185 mL size fits a standard caulk gun and the 450 mL cartridge fits a professional-grade, dual cartridge gun.

Gluzilla Fast

Gluzilla Fast is the little brother to our extremely popular Gluzilla cartridge adhesive. Just like Gluzilla you can just grab and go, but Gluzilla Fast offers a quicker cure time so you can move on faster. It is great for cooler ambient temperatures due to its accelerated cure time.


Crackzilla was born at our manufacturing facility when we needed to quickly get our concrete floor back to level ground. With the Crackzilla cartridge we were able to fill cracks and holes in less than half the time it would have taken to mix and pour into the same areas, and with none of the mess. There are many creative uses for Crackzilla, including using as your laminating epoxy, filling holes or cracks to create a smooth surface and even jewelry design.


Try Woodzilla for your next filleting project, instead of adding the wood flour on your own. When you buy Woodzilla you are letting us worry about adding the correct amount of wood flour so you just get to enjoy creating beautiful fillets. Just like the other cartridges each Woodzilla comes with two static mixers so you can use the same tube several times.
