发明名称 ADHERING GRAPHIC FILMS ON IRREGULAR SUBSTRATES
摘要 Methods of adhering graphic film on an irregular substrate are disclosed. The methods includes providing a polymer film composite having two or more layers with at least one layer having a glass transition temperature of at least about 40° C., the polymer film composite having a first side and a second side, and an adhesive layer disposed on the second side. Then the method includes, positioning the adhesive layer against the irregular substrate, heating the polymer film composite, and pressing the heated polymer film against the irregular substrate.

主权项 1. A method of adhering a composite film to a masonry substrate having an irregular surface, the method comprising steps of: positioning an adhesive-backed composite film against the irregular surface of the masonry substrate, wherein the composite film comprises two or more polymer layers, with at least a first polymer layer having a glass transition temperature of at least about 40° C., and with at least another polymer layer having a glass transition temperature of less than the glass transition temperature of the first polymer layer, and wherein one of the polymer layers is substantially transparent to visible light; heating the polymer film composite to the glass transition temperature of at least the first polymer layer to form a heated composite film; and pressing the heated composite film against the irregular substrate to bring the adhesive into intimate contact with the irregular surface.
