Get a Complete Cure for Polyester Resins
Add Styrene Wax to non-waxed polyester resin and gel coat to prevent the prolonged tackiness associated with thin sections of polyesters in your composite.
This Styrene Wax is a 5% paraffin dissolved in styrene. When paraffin is added to resin, the wax will rise to the surface and protect the curing resin from the inhibiting action of the air. Once the resin is allowed to fully cure, it must be sanded off prior to any additional applications. Any paraffin on the surface will prevent adhesion of further coats.
Mix #71 at 5% for thin coatings—approximately one to two tablespoons for every pint of resin. When performing repairs below the water line, use with #1040 Hi-Gloss Additive.
