Improving the storage stability of therelease film
Polyorganosiloxane molecule radicalreactive functional group content is large, it can improve the electron beamcuring type silicone releasing agent curability. However, due to the polarityincreased, also release film hardness and surface tension becomes large,leading to peeling deteriorates. Especially acrylics adhesives, small initialpeel force after placing larger. Phenolic antioxidant added to allylgroup-containing polyorganosiloxane, it is possible to improve the storagestability of the peel force.
