NEW Hycat™ XP-1

Improved Tg Performance for Anhydride Curing

Hycat™ XP-1 is the very latest product to be added to our Hycat™ line. A low viscosity liquid, this catalyst is designed to accelerate the reaction of a broad range of epoxy resins with a wide variety of anhydride curing agents. Like Hycat™ 3100S and Hycat™ AC-4, Hycat™ XP-1 dramatically reduces the onset temperature of an epoxy/anhydride reaction and when compared to other catalyst systems the curing kinetics of Hycat™ XP-1 yields a much more gradual exothermic profile. This distinctive curing characteristic allows for quicker gel times at lower temperatures without inducing an overly rapid cure or sudden spike in the exotherm of a polymer reaction. In addition, Hycat™ XP-1 provides a 20% to 30% improvement in Tg performance and still maintains excellent room temperature pot life (25oC). These unique features combine to greatly enhance process flexibility and produce polymer cures of exceptional quality.

Improved Tg Performance

Hycat™ XP-1 produces 20-30% higher Tg values vs our Hycat™ 3100S and Hycat™ AC-4 without the addition of a co-catalyst, yet retains the low onset and relaxed exothermic characteristics that make Hycat™ Catalysts so unique and versatile.
