Polyester Resin Kits - contain high 'tradesmen' quality resin from either Australian or imported suppliers. Polyester resins are the most commonly used matrix in the marine and composite industry. These resins are styrene-based, and so threrefor flammable and catalyzed when combined with Methol Ethyl Ketone Peroxide (MEKP) - available in our store.

When working with these resins in large projects it is advised to use goggles, gloves and a chemical respirator to protect yourself from the fumes. These resins can be used with any type of fibreglass, carbon fibre or kevlar, as well as used over urethane foams and other sandwich core materials. These resins tend to be fairly rigid when cured and also more brittle than epoxy resins.


Directions for use: Mix resin and hardener in the ratio shown on the label and apply to saturate Fibreglass Cloth, Chopped Strand Mat or other materials.


Coverage: It takes about 250 grams of resin to saturate a meter square of Fibreglass Cloth (200gram weight) or about 1 kilogram of resin to saturate 1 square meter of Chopped Strand Mat (450 gram weight).


Polyester Resin has a blue or pink colour initially that disappears when MEKP hardener is added and cures to form a slightly honey colour.


Please note: Polyester Resin is LSE (Low Styrene Emission). LSE resin can be used as either waxed or unwaxed Polyester Resin. If you specifically require unwaxed resin? Then please let us know in the comments section of the order / checkout.
