The invention relates to compositions containing at least one siloxane which comprises ethylenically unsaturated, radically polymerizing groups, and at least one hydrocarbon with ethylenically unsaturated, radically polymerizing groups, which have, when used as a separating coating, an improved barrier effect.

Permeation-inhibiting release coating

A composition contains at least one siloxane having ethylenically unsaturated, radically-polymerizable groups, and at least one hydrocarbon having 2 to 6 ethylenically-unsaturated, radically-polymerizable groups, and can be used as a release coating, said composition allowing a good degree of release behavior from adhesive compounds while at the same time also achieving a high level of adhesion of the coating to the carrier material.

Radiation-curable coating compounds consisting of a plurality of components, and the use of same in release-coated substrates

Composite membrane having a separating membrane layer characterized in that a separating membrane layer is produced by curing laterally modified silicone acrylates of the general Formula I 

Composite silicone membranes of high separation efficiency

The invention provides radiation-curing coating materials composed of at least one silicone resin modified with vinylalkoxysilane and vinylcyclohexene oxide and of at least one epoxy-functionalized polysiloxane and of a cationic photoinitiator. Furthermore, coinitiators may also be a constituent of the mixture, in order to obtain increased reactivity of the formulation.

Cationic radiation-curing controlled release coating materials

The invention relates to a durably homogeneous, low-viscosity, radiation-curable coating material comprising
