Abstract

Compositions comprising at least one siloxane which has ethylenically unsaturated, radically polymerizable groups, and also comprising at least one hydrocarbon which has 2 to 6 ethylenically unsaturated, radically polymerizable groups when used as a release coating enable good release characteristics with respect to adhesive materials and at the same time also attain good adhesion of the coating to the carrier material.

Description

technical field [0001] A composition comprising at least one siloxane having ethylenically unsaturated radically polymerizable groups, and at least one hydrocarbon having 2 to 6 ethylenically unsaturated radically polymerizable groups, when When used as a release coating, good release properties with respect to binder materials are obtained, while good adhesion of the coating to the carrier material is also obtained. Background technique [0002] Polysiloxanes containing (meth)acrylate groups are identified as adhesives curable under high-energy radiation, for example as coatings for plastic and paper surfaces. Specifically, curing is accomplished by UV radiation (after addition of known photoinitiators) or electron beams. (Meth)acrylate-modified organosiloxanes are described in numerous patent specifications, for example in US 6,211,322 and US 4,978,726. [0003] Within a short time, (meth)acrylate-modified organosiloxanes can be three-dimensionally crosslinked into free ...
