CoREZYN^® Brand Resins, Gel Coats and Colorants

The Thermoset Resins Division was the foundation upon which Interplastic Corporation gained its reputation as a polyester resins leader. We've been formulating isophthalic and orthophthalic polyester resins since 1959 under the CoREZYN brand name and we pioneered much of today's vinyl ester technology. Interplastic offers the most extensive library of polyester resin formulas in the industry. There is also a complete line of CoREZYN brand gel coats and colorants.

We support the Fiberglass Reinforced Plastics (FRP) industry and Cast Polymer/Solid Surface industries by directing all our technical ingenuity and manufacturing resourcefulness at your applications. Our technical experts and laboratory testing facilities are always available to formulate resins and gel coats for a new application, troubleshoot a problem or to assure you that the formula you chose is not only going to work, but also enhance the overall performance and quality of your finished product. We are the resin specialists.

CoREZYN products are manufactured in Minneapolis, Minnesota, Vadnais Heights, Minnesota, Pryor, Oklahoma and Kent, Washington. Our products are supported by the most professional, well-trained distributor network in the industry.
