Low emission gel coat has less Volatile Organic Compounds (VOC) with 25% less styrene and 40% fewer emissions when spraying compared to standard gel coat. Low emission gel coat may have a slightly more sluggish cure than a typical gel coat. To ensure a full cure, keep ambient temperatures of at least 70°F through the entire cure schedule. Spray the gel coat in 3 passes of 5 mils each, allowing the gel coat to flash off between passes.

Tooling Gel Coat is an abrasion resistant gel coat for making molds where gloss retention, superior hardness, exceptional craze resistance and minimum distortion are paramount. The life of a good polyester mold may be extended considerably by the use of tooling gel coat. For best results, build the film thickness to 20 -25 mils. #1040 Hi-Gloss Additive can be added to further upgrade the gloss.

#1040 can be mixed 1:1 with regular gel coat to reduce viscosity, porosity, and permit a complete open air cure. The reduction in viscosity allows gel coat to be sprayed controllably through siphon and HVLP equipment, reducing sanding and polishing time. Below the waterline repairs still need the addition of #71 Styrene Wax for maximum hardness. Requires 2% MEKP. 

#70 Styrene Monomer is the recommended and accepted thinner for polyester resins and gel coats. Most gel coats can be thinned 2-5% to make them suitable for heavy spray equipment or other special purposes.   

# 71 Styrene Wax is a 5% solution of paraffin dissolved in styrene that may be added to non waxed polyester resins and gel coats to prevent the prolonged tackiness associated with thin sections of polyesters. If the resin contains paraffins, the wax will rise to the surface and protect the curing resin from the inhibiting action of the air. However, if the resin is allowed to fully cure, the paraffins on the surface will prevent adhesion of further coats of resin and must be sanded off prior to additional applications. We recommend adding #71 at 5% for thin coatings. Use with #1040 Hi-Gloss Additive when performing repairs below the water line. 

#69 MEKP is required with all Polyester Resins, Gel Coats and Vinyl Ester Resin. It is required in different concentrations as defined for each resin product. Each resin product is available as a kit with the correct amount of hardener. However, hardener may be purchased individually as shown here.
