The polarity of the interface between the coating material body and the support material is seriously mismatched, that is, the interface Problems; 2. The existence and migration of residual monomers (including UV photoinitiators), oligomers, and polymer fragments lead to many subsequent problems (residual adhesion is an apparent phenomenon, and the appearance is a static problem, but in fact it is a dynamic problem ); 3. The performance requirements of non-silicon release agents (not including F-containing materials) are too demanding, resulting in a slow process of research and development (for example, the peeling force is required to be ≤10g/25mm); 4. The solvent used in the coating is applied to the coating The layer/supporting film interface has a certain influence.
