Study on the Curing Activity of Polyether Polyurethane Acrylate Resin for LED
This paper synthesized three types of polyether acrylate resins with different molecular weights and judge the response activity of different resins to 395 nm LED polymerization by UV-DSC.The results show that polypropylene glycol urethane acrylate resin has the highest response activity to LED curing,and the polymerization activity of poly ether urethane acrylate resin gradually decreases with the increasing of molecular weight.
