Gelcoat

Not all gel coats are created equal Our premium, high-viscosity marine gelcoat is non-sagging, and super strong. In fact, its ISO/NPG (Isophthalic/Neopentyl Glycol) resins are considerably more durable than standard, orthophthalic resin formulas. TotalBoat marine gel coat can be colored prior to adding catalyst. Adding color to Neutral gel coat produces bold or dark colors; adding color to a white gelcoat creates lighter, pastel colors. Gel time depends on amount of catalyst admixed Adjust the catalyst level to slow down or speed up gel time. Cooler temperatures may require a higher percentage of catalyst than warmer temperature conditions. Proper catalyzation is imperative for proper cure when using polyester. The higher the percentage of hardener, the faster the gelcoat will dry. Because air and surface temperatures also affect the drying of gelcoat, take care not to over-catalyze or under-catalyze. Do not add less than 1% catalyst or greater than 3% catalyst. We recommend a trial batch to determine final catalyst ratio. Gelcoat With Wax (for Finishing) Details Contains wax so additional patch aid additives are not required. Cures properly without PVA, wax paper, or special tools. Non-sagging formula fills superficial scratches. Deeper scratches require a filler such as TotalBoat Silica Thickener added to the gel coat. Gel coat can be mixed with coloring agents made specifically for polyesters (sold separately). Catalyst: MEKP (methyl ethyl ketone peroxide), included Colors: Available in Neutral & White Sizes: Neutral is available in Quarts only; White gelcoat is available in Quart and Gallon sizes Gelcoat Without Wax (for Layups) Details Does not contain a wax additive, making it ideal as the first layer when building a boat hull or composite part on a prepared mold. Non-sagging formula can be mixed with coloring agents made specifically for polyesters (sold separately). Catalyst: MEKP (methyl ethyl ketone peroxide), included Colors: Available in Neutral and White. Sizes: Neutral gelcoat is available in a Quart size Kit only; White gelcoat is available in Quart and Gallon size Kits. Note: Wax Additive is available to add to Gelcoat Without Wax so it cures to a tack-free surface.
