#83 is a waxed resin for laminating thin fiberglass skins on plywood, or for general purpose fiberglass repairs. The wax in the resin will prevent surface tackiness even when applied in thin coats. Sand off the wax layer before painting or secondary bonding. Stir thoroughly in can before using.  Requires 1% MEKP.

83/69-A kit contains (1) QUART RESIN, (1) 69-A.
83/69-AK kit contains (12) QUARTS RESIN, (12) 69-A.
83/69-B kit contains (1) GAL RESIN, (2) 69-A.
83/69-BK kit contains (4) GAL RESIN, (8) 69-A.  

#77 Molding Resin is ideal for general purpose part fabrication and for building low cost molds. An internal thickening agent has been added to prevent drainage on vertical surfaces, yet it retains the low viscosity required for rapid wet out. This resin is wax free to reduce sanding between coats. Requires 1% MEKP.

77/69-F kit contains (1) QUART RESIN, (1) 69-A.
77/69-A kit contains (1) GAL RESIN, (2) 69-A.
77/69-AK kit contains (4) GAL RESIN, (8) 69-A.  

#90 Iso Polyester is perfect for making dimensionally stable polyester molds, corrosive service part fabrication, and as a durable repair material for tank linings. #90 permits fast wet-out in spray or hand laminates. It's 225 degree F service temperature also resists exotherm and post cure problems. Properly fabricated parts may be used in food contact applications. Meets MIL-R-7575C.  Requires 1% MEKP.

90/69-F kit contains (1) QUART RESIN, (1) 69-A.
90/69-A kit contains (1) GAL RESIN, (2) 69-A.
90/69-AK kit contains (4) GAL RESIN, (8) 69-A.  

#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.
