MTHPA-C8K is a precatalyzed unique blend of MTHPA isomers that have been partially hydrogenated. It has been designed to optimize both physical and electrical properties, and has the advantages of low viscosity and near water white color. It already contains a level of accelerator that allows for ease of use. Major applications of MTHPA-C8K are in structural composites where higher Tg and improved outdoor weatherability are desired. Other major applications are in the formulation of epoxy encapsulation and vacuum impregnation compounds including resin infusion systems. MTHPA-C8K is well suited for applications that are subject to high temperatures, high voltages and high humidity.
