UV-Curing Behavior Novel Type Functional Monomer which made from Melamine Backbone

摘要

UV system of PSA is classified two categories. The first is UV-polymerized system and second is UV-curing system. When we use acrylate monomer in PSA process, the PSA do not have heat resistance and that is not easy to control properties. So we use the latter system. UV curing PSA have exceptional advantages in process of control properties such as peel, tack, heat resistance and ETC. So materials curing behavior is very important in UV-curing system. There are many types of monomer which have different backbone and side chain. Especially, melamine acrylate has many advantages. But if we want to use the acrylate they have photo activity enough. Monomers backbone can effect on UV-curing behavior. So in industry, monomers reactive condition must be optimized. In this study we analyze monomers reaction -curing time, conversions, shrinkage, initiating time -by FT-IR, shrinkage meter, photo-DSC.
