They are suitable for boats, truck cabs, water slides and environments with humidity and direct sun exposure. Web mek, short for mekp, is the “hardener” or catalyst for polyester resin and vinylester resin systems including isothalic and gelcoat. Due to the lower monomer content for low emissions, we suggest catalyzing the le gel coat at 2% depending on ambient temperatures. Web mixing cup will give exact measurements for larger volumes in cc and ounce increments. High quality marine grade fiberglass gelcoat. Gelcoats are based on a thermoset resin that requires an initiator and proper temperatures to cure thoroughly. Web gel coat can be mixed with coloring agents made specifically for polyesters (sold separately). Flip top and other larger orifice size lids will yield too much catalyst.
