The first adhesive layer may include one or both of a hot melt adhesive and a butyl rubber-based adhesive. The roofing membrane may include a UV curable adhesive layer disposed on the first adhesive layer. The UV curable adhesive layer may have a thickness of less than about 4 mils.

A method of applying an adhesive film to a component includes applying an adhesive film to a surface of a component, wherein the adhesive film is positioned between the surface and an elastic membrane, the elastic membrane is transferred into a curved state with a convex and a concave side and contacted with the surface with the convex side first such that an adhesive layer of the adhesive film is pressed onto the surface in a full-area by the elastic membrane, the adhesive layer is pressed onto the surface in a full-area by a negative pressure being applied to that side of the elastic membrane facing towards the adhesive film, and to stabilize the component against deformation brought about by this negative pressure, the elastic membrane along with the adhesive film is pushed against the surface of the component with a plunger means.

The present invention discloses an ultra-quiet backing-paper-free cold laminating film comprising a substrate layer, a release layer, and an adhesive layer, the release layer and the adhesive layer being each attached to a respective side of the substrate layer, the release layer being obtained by drying a release agent applied on the substrate layer, and the release agent consisting of the following components by weight: 2-ethylhexyl acrylate, vinyltrimethoxysilane, 1-methyl-1-phenylethyl hydroperoxide, vinyl-terminated silicone resin, di-t-butyl cumene peroxide, fluorosiloxane, ethyl acetate, ethylene glycol dimethyl ether, a toughening agent, polysiloxane-polyether copolymer, silicone and wax powder. In the invention, the peel strength is reduced; it is ensured that the release force of the cold laminating film is not affected by the external environment, such that the cold laminating film has good stability; and meanwhile the subsequent adhesion of the release layer is improved, so that it can ensure that the adhesive force of the adhesive layer would not be affected after long-term adhesion between the adhesive layer and the release layer.

A photosensitive medical tape includes a backing layer that is at least partially transparent to a first spectrum of electromagnetic radiation. The photosensitive medical tape also includes a coupling layer disposed on a first side of the backing layer to provide adhesion of the photosensitive medical tape to the human skin. The photosensitive medical tape is disposed to absorb a second spectrum of electromagnetic radiation to decrease a strength of the adhesion provided by the coupling layer. The photosensitive medical tape is also flexible.
