Hycat™ Catalysts

Hycat Catalysts, developed by Dimension Technology Chemical Systems, Inc. (DTCS), are liquid reaction accelerators that achieve truly unique curing performance for thermoset applications. Hycat Catalysts, recognized for ease of catalyst handling, can dramatically reduce reaction onset temperatures; however, the curing kinetics are completely different from that of other commonly used catalysts such as imidazoles or amines. Where other catalysts quickly spike at onset and release most of the reaction energy in a very short period of time, Hycat Catalysts have much more gradual exothermic profiles that begin at significantly lower temperatures. These performance features produce greater processing flexibility by allowing formulators to have more control over initial cure temperature, gel time, and early polymer manipulation, and better heat dissipation.
