Release coating, also known as anti-adhesive agent, is applied between the substrate and the pressure-sensitive adhesive layer. Its core function is to protect the pressure-sensitive adhesive layer coated on the substrate to prevent the pressure-sensitive adhesive layer from being contaminated or losing its effectiveness due to adhesion to other items. Whether it is a film substrate, baking paper, self-adhesive envelope, or sanitary products, release coating plays an extremely critical role. Among the release coatings commonly used in release films, silicone release coatings are one of the most common types.


From the perspective of reaction mechanism, release coatings can be divided into three types: addition, condensation and radiation curing, which are commonly referred to as platinum catalysis, organotin catalysis, UV and EB curing. If distinguished by product shape, it can be divided into solvent-based, solvent-free and emulsion types.
