UV-curing release coating

The radiation curing silicone release agent is mainly UV radiation curing. The release agent is usually divided into two reaction types: free radical and cationic. The acrylate release coating belongs to the free radical, which must be protected by nitrogen during the reaction. The free radical has low requirements on the substrate and has no post-curing; In addition, it has almost no effect on thermal shrinkage and deformation of the substrate, and acrylate silicone release coating can be widely used for the coating of paper and film substrates.
