HK Tooling Gelcoat - top of the line in Orange. HK Research Corporation's Isophthalic Tooling Gel Coats are designed to provide the hard, durable, high-gloss surface required in a superior grade polyester tool. The toughness and chemical resistance of these tooling gel coats will develop within 24 - 48 hours after lamination and removal from the master or plug. This rapid development of physical properties allows the mold builder to develop the high-gloss, mirror-like finish required in polyester molds.
A Word About How Containers are Filled: The unit of measure for pints, quarts, gallons, and 5 gallon pails denotes container size and not the actual volume of the liquid inside. Products are dispensed by weight, with varying amounts of head space in the can or bottle to accommodate mixing, expansion, and shipping requirements. In the case of epoxies, the available cans in standard sizes will often appear “short” on resin or hardener to accommodate a true ratio.
