Study on influence of epoxy resin for UV curing system

Abstract

This paper chooses the radical cationic hybrid UV curing systems and oxetane cationic UV curing system as rapid prototyping, studies the performance of the system as the change of the kinds and the amount of pre-polymer, and the impact of the ratio of the pre-polymers to the system volume shrinkage. Studies show that the type and content of the pre-polymer have a great impact on the system volume shrinkage, and analyze the result from the perspective of the theory. The results shows that the epoxy resin can reduce the volume shrinkage hybrid UV curing system and can also improve the flexibility of the material cured film.
