Ring Tensile Test of Modified Halthane 88-2

摘要

Seven adhesives, designated Halthanes, have been developed at the Lawrence Livermore National Laboratory. This research deals with the stress-strain behavior of Halthane 88-2 and a surfactant modified version of this adhesive as a function of aging time and temperature. The urethane adhesive, Halthane 88-2, consists of prepolymer 88, curing agent XU-205, FC-430, with 88/12/0.25 weight ratio, respectively. Ring tensile measurements were made on control samples and samples aged at elevated temperatures on a logarithmic time scale. The temperatures were 60 exp 0 C, 75 exp 0 C and 100 exp 0 C, and aged for 3 days, 10 days, and 28 days. (ERA citation 09:012391)
