STUDY ON CURING CHARACTERISTICS OF UNSATURATED POLYESTER RESIN WITH TBPB/TBPO

Abstract

Abstract: The curing behavior of unsaturated polyester with complex initiation system TBPB/TBPO was studied by dynamic DSC. The effects of curing system by different content of TBPO were compared. With the increase of content of TBPO from 10% to 100%, the curing temperature was decreased from 142℃ to 120.8℃. Simultaneously, the gel time was reduced from 214s to 79.5s and the cure time were found to decrease from 634.4s to 171.5s.

Key words: unsaturated polyester, TBPB, TBPO, curing
