Abstract
Sheet materials according to the present invention comprise a sheet material substrate, such as for example a film or paper sheet, with a polymer release coating overlying and adhered to a surface of the sheet material substrate. Single and multilayer release coatings can be formed on the substrate by vapor deposition of silicone acrylates and/or fluorinated acrylates. These coatings can be applied in thickness of 0.05 micron to 1.0 micron to achieve a range of release properties. These coatings can be applied in a very thin single layer on relatively smooth substrates or in a multilayer form on rough substrates such as paper. The new coating process described here has lower process and materials costs, improved adhesion, low slip, and excellent release characteristics.
