Abstract:
1. A process for adhering a flexible film to a substrate, comprising interpositioning between the film and the substrate of a sufficient amount of a liquid, so that no bubbles are trapped between the film and the substrate after the film has been applied to the substrate using a scraper, wherein the liquid does not freeze at a substrate temperature below 0° C. wherein the liquid interposed between film and substrate comprises an effective amount of an antifreeze compound selected from the group consisting of KCl, NaCl and a combination thereof that lowers the crystallization temperature in solution and/or alcohol, and/or a suitable hydrophilic polymer, copolymer, prepolymer or oligomer, optionally in water, and optionally one or more surfactants.
