Silicone anti-blocking agent bycross-linking mechanism can be divided into condensation type, addition typeand radiation type. From the comparison of the degree of curing, working time,release properties, blocking resistance and coating formulations and otheraspects of design freedom, plus molded advantage more condensed than iscurrently the main varieties of organic silicon release agent. Ultravioletlight and electron beam radiation curing many theoretical advantages. However,due to the typically silicone polymer to ultraviolet light and electron beamradiation are not sensitive. To be synthesized with acryloyl, epoxy, mercapto andother radiation-sensitive functional groups polyorganosiloxane or joinphotosensitizer job. And such polyorganosiloxane and a difficult, highproduction costs, not mass production. Therefore, such a silicone releasingagent is currently only a very small market share. Silicone anti-blocking agentthe form of products divided solvent, emulsion and solvent-free three kinds. Solvent-existingproblems of environmental protection and safety. So, currently being highconcentration of the coating liquid and solvent-type transition. Industrialcountries solventless silicone release agent accounts for more than 60% of theproduct mix. By emulsion without using a solvent, but also attention.
