9. Silicone Release Coatings for the Pressure Sensitive Adhesive Industry

Release liners are part of a composite made of a label with its own adhesive on a release liner or carrier with its own release coating. The label comprises either a synthetic face stock such as polypropylene or paper. The adhesive is usually an organic material such as a polyacrylate or polyisoprene based rubber. The release liner can be made from various substrates treated with a suitable product, the release coating. Such release liners allow transporting labels with their adhesives from the point of manufacture to the point of label application (e.g., a filling station of some sort). The release coating allows easy delamination or easy label transfer from their liners onto the object to be labeled.
