Hydrite Advanced Resins introduces new epoxy resins

October 14, 2011

Hydrite Advanced Resins, LLC (HAR) introduced two new epoxy resins for a wide range of composites, coatings and adhesive applications at the recent 2011 Thermoset Resin Formulators Association (TRFA) annual meeting in Niagara Falls, Canada. Two grades of Resorcinol Diglycidyl Ether (RDGE), a difunctional aromatic resin, are now offered by HAR. HAR 2120 has properties that are similar to other commercial RDGE resins, including a relatively low viscosity (500-1,000 cps), making it a good choice as a reactive additive to reduce viscosity while enhancing physical properties, the company said. HAR 2140 is a higher molecular weight RDGE with viscosity of 3,500-4,500 cps enabling the formulator to use HAR 2140 in higher concentrations or even as the sole resin system. In addition, unlike HAR 2120 and other commercial RDGE resins, HAR 2140 will not crystallize in storage eliminating the need for heated storage and/or melting ovens, the company said.
