Abstract:

Using the H-H method, a resin composition of Epon 15-Versamid 140 was evaluated to determine the effects of Versamid 140 on the hardness of the cured resins. It was found that compositions containing 60, 65, and 70 Versamid 140 had hardnesses, in terms of mean penetrating loads, of 154.8, 81.9, and 1.50 lb, respectively. Eighty percent Versamid 140 and above in complete cured resin samples were obtained. Maximum hardness of 75 on the Barcol Tester was obtained in a composition of 7030 Epon 815Versamid 140. Author
