  • Stabilized paper substrate for release liners using aromatic and aliphatic primers, and novel primer coat
    Patent number: 5358977
    Abstract: The invention is a method of manufacturing a substrate and, particularly, of manufacturing a release paper. The method comprises coating a release paper base with a primer coat, and curing the primer coat. The cured primer coat is then overlayed with a heat-curable or an ultraviolet-curable silicone coating which is, in turn, cured with heat or ultraviolet light. A product manufactured in accordance with this method enables a facing adhered to this release paper to be removed relatively easily from that release paper.
