MAS Low Viscosity Epoxy Resin is a blend of standard low molecular weight epoxy resin. 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.The reduced viscosity of MAS Epoxy Resin provides for complete wet out of fibre 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.
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.
Remember MAS is a NO WAX NO BLUSH EPOXY
low vis is available with fast medium or slow hardeners

MAS EPOXY comes with a choice of three different hardeners. Each hardener will produce a blush and wax free finish allowing easy over coating with further layers of epoxy, epoxy and cloth or final paint varnish finish.
MAS FAST CURE HARDENER
MAS FAST HARDENER can be used as an accelerator for MAS Slow and Medium Hardeners when customized cure times are required. Appropriate applications of MAS FAST hardeners formulas include hardware bonding, spot filling, and fairing. Additionally, the superior bonding strength of MAS FAST hardener mix is ideal for high strength secondary bonding applications such as structural tabbing and repair lamination’s.
The rapid cure time of MAS FAST hardener allows overnight curing in low temperature conditions so your project can be sanded next day
We do not recommend mixing more than 140 grams. of formula unless rapid application techniques are incorporated.
An induction time of 1-2 minutes is recommended prior to application of formula. We have found the low viscosity of MAS FAST hardener allows for fast wet-out of the heavy reinforcing fabrics often used in repair applications. MAS SLOW or MEDIUM may be blended with MAS FAST to retard the mix of the MAS FAST hardener when customized cure times are required.
Remember Surfaces coated must be carefully prepared prior to re coating and bonding dust and grease free and a good scratched key over the whole area to be bonded
MAS MEDIUM hardener has a moderate gel and thin film set times providing great advantages when filleting and fairing. MAS low vis and flag resins when mixed with Medium hardener and the appropriate thickener will gel and set quickly enough to avoid draining out and sagging, while still giving you the time to get the job done. We recommend this hardener when “overnight” sanding is more important than continuous laminating and open time (as provided by MAS SLOW Hardener)
MAS MEDIUM hardener will also provide a beautifully smooth void free finish with great resistance to milking out during application and fogging in critical clear coating applications..
Cure speed gelling and thin film set can be adjusted by adding either slow hardener or Fast hardener as needed but the mix must remain 2 parts resin to 1 part hardener
This is our standard hardener that we recommend for all gluing and fairing work , provided the customer is experienced enough and happy to work at a faster rate. However when wetting out multiple thickness of cloth we recommend slow hardener to ensure the epoxy hardener mix has properly wet out before it starts to gel
MAS SLOW hardener is a hardener that will give you a working pot life of 30 – 35 minutes , when used with MAS LOW VIS or MAS FLAG resin at a ratio of 2 parts resin to 1 part hardener it gives a good extended gel time allow you to control the application
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
We recommend MAS SLOW hardener when working on large areas and on cloth were we want the maximum amount of penetration before gel starts. slow hardener can be mixed with our other hardener to get the correct working time for your application
As with all our hardeners MAS SLOW is blush and wax free there is no need for any wash down between coats (if the surface can be marked with your thumb nail , then you can go straight on top if it can not a simple roughing or abrasion is needed to give a good key)
Use: If you are a beginner to the use of epoxy we recommend that you choose slow hardener, this gives you an extended pot life enabling you to take time on your work and giving you the opportunity to correct any thing along the way. When doing large areas or when large mixes are needed always consider MAS SLOW hardener first.
Caution: Not recommended for use below 8 degrees C unless cure time is available.
This means that you simple have to give the product longer so if it is below 10 degrees C yes it will work but you have to wait but as a policy we would recommend a quicker hardener the cooler it gets
Remember you can mix MAS SLOW with MAS MEDIUM AND MAS FAST to achieve a work and cure time you want but the mix ratio must remain 2 parts resin to 1 part hardener
