A METHOD TO ACHIEVE A RELEASE MATERIAL COATING, RELEASE MATERIAL AND BASE MATERIAL FOR RELEASE MATERIAL

摘要

In the method for producing a release coating in the manufacture of a release material (R), such as release paper, a release agent based on silicone polymers is spread on top of a backing material (1), which release agent is catalytically cross-linked. The backing material (1), onto which the release coating (3) is spread, incorporates the coating's cross-linking catalyst. The cross-linking catalyst may be platinum or another catalytically active noble metal or tin, and it is spread onto the surface of the backing material acting as a base paper or added to the pulp stock for the base paper before formation of the paper web. There is no need for heating as used in previous methods to activate the catalyst.
