MAS Epoxy Products on Sale


You don't need to thoroughly know epoxy resin chemistry before using MAS epoxies, but it does help to have basic knowledge that will allow you to complete a project more efficiently and avoid the pitfalls or surprises which may arise when using epoxy resins.

MAS manufactures epoxy resins in several viscosities and drying times, so the resulting material can be customized to suit your project.

Measuring and mixing is extremely easy with MAS epoxy systems because they mix at a 2:1 volume ratio (except for the Rapid Cure, which mixes at a 1:1 ratio), and you can pre-mix any of the MAS hardeners to get custom curing times, and then add the pre-mixed hardener to the epoxy resin. However, this does not mean you can ignore what you are doing. Be certain to read Technical Data Sheets for the products that you are using before you start on a project.

As with all epoxies, you should use caution when using epoxy resins and polyester resins, because epoxy resins may be applied over cured polyesters that have been de-waxed and well sanded, but polyesters should never be used over cured epoxy resins because the unreacted amine in the epoxy inhibits the peroxide catalyst in the polyester resin, which causes an incomplete cure. Sanding does not get rid of unreacted amine in the epoxy, and the result is a very poor bond even though the surface appears to be fully cured, and it will de-bond over time.
