PRE-ACCELERATED ORTOFTPALIC POLYESTER RESIN
The orthophthalic polyester resins are based on phthalic anhydride and glycols, they are also called general use, since they are those of greater application with reinforcing material. They have little chemical resistance and corrosion.
They are used in the manufacture of boats, transports, bathtubs, pieces in general, gelcoat, putties, among others.
To achieve polymerization (curing) requires the addition between 0.8 and 1.5% of 50% MEKP Catalyst.
