Crosslinking effects on the release force of addition cure silicone release agents in model systems

Crosslinking effects on the release force of some addition curable silicones in a model system have been investigated. The release force at several release speeds and the contact angles of ethyleneglycol on release papers coated by release agents having different crosslinking densities were estimated. Physical properties of model release agents in the bulk were also measured in bulk. We found that release force at a low speed is affected by the wetability of the surfaces and release force at a high speed is affected by the bulk crosslinking density.
