Abstract:

A primary high temperature, 32 to 125 F RESIN AND A SECONDARY low temperature, -15 to 65 F resin are developed as surfacing materials which meet predetermined requirements in viscosity, gel time, cure, mechanical strength, shelf life, combustibility, additives, chemical and weather resistance, and cost. The primary resin system is composed of 76 ALTEK 8-52 and 24 DERAKANE 510. The secondary resin system consists of 90 COREZYN 1042-14A FORMULATED WITH ADDED STYRENE AND MONOCHLOROSTYRENE, AND 10 DERKANE 470. The catalystpromotergel retarder for both resin systems is CHPDMTPERCADOX 48 with the concentration dependent on the temperature of application and gel time desired. Author, modified-PL
