A protective film for back-grinding wafers primarily includes a base layer and a multi-film structure. The multi-film structure at least includes two TPU films, wherein the one (HPTU film) having a higher Vicat softening temperatures and/or heat deflection temperature than the other (LPTU film) contacts the base layer. The protective film optionally includes an adhesive film on one side of the LTPU film. The multi-film structure may include one or more TPU films between the HPTU and the LPTU films.

The present disclosure relates to a color wrapping film for a vehicle, which has an excellent impact resistance and excellent scratch restorability due to a base layer and a coating layer formed of a polyurethane-based material, and suppresses discoloration caused by an external environment by adding a color pigment to a separate layer.

A tint film for application to a target surface, such as a headlight, includes a release liner, an adhesive layer, an at least partially transparent cast layer, and a tint layer. The tint layer is provided as an at least partially light-transparent layer, which may be printed upon the at least partially transparent layer using an ink-jet printing process. In addition, the adhesive layer is configured to have low-tack, so as to facilitate the ease in which the tint film is applied. In some cases, the at least partially transparent layer and the at least partially light-transparent tint layer may be formed together as a composite layer in a casting process.

A laterally-coiled adhesively-retained low force backer for installation prior to application of a liquid sealant with sufficient surface adhesion to remain in place for such application and curing.

Adhesive articles include a substrate; and a hot melt processable pressure sensitive adhesive on the substrate. The hot melt processable pressure sensitive adhesive is a (meth)acrylate-based copolymer that is the reaction product of a reaction mixture that is free of acidic or basic monomers, and includes an alkyl (meth)acrylate, a hydroxyl-functional (meth)acrylate, and a photocrosslinker. The (meth)acrylate-based polymer is prepared in a thermoplastic package.

The present invention provides a UV debondable pressure sensitive adhesive composition and an adhesive tape comprising the same. The UV debondable pressure sensitive adhesive composition comprises a polyacrylate pressure sensitive adhesive, a UV-light polymerizable polyurethane oligomer, a cationic photoinitiator and a free radical photoinitiator, wherein polymerization monomers of the polyacrylate pressure sensitive adhesive comprise an acrylic monomer having an epoxy functional group. The UV debondable pressure sensitive adhesive composition has a bonding force dropping significantly upon UV irradiation, and leaves no residual adhesive.

Provided herein is a flame retardant label suitable for labeling electrical devices. The disclose label includes a coating layer, a film layer, an adhesive layer, and, optionally, a liner layer. The coating layer and the adhesive layer may include flame retardants. The flame retardant label may also include channels that provide for air egress during application of the label.

The disclosure relates to a car glass protection film having a self-restoration performance. More specifically, the film comprises: a substrate layer; a urethane coating layer formed on one surface of the substrate layer; a self-restoration layer formed on the upper surface of the urethane coating layer; a protection film layer formed on the upper surface of the self-restoration layer; and an adhesion layer formed on the other surface of the substrate layer. A car glass protection film having the structure described above does not show a separation phenomenon, which may be caused by temperature change, ultraviolet light, and external impact, exhibits excellent impact resistance by the urethane coating layer, and can recover from fine scratches by the self-restoration layer.

Provided is a composite film for attachment to an elastomeric substrate. The composite film comprises the following layers, in the order below: an elastomeric layer comprising a thermoplastic polyurethane; an ink layer; and a pressure sensitive adhesive layer comprising a styrenic block copolymer blended with a phenolic resin. Advantageously, the provided composite films can withstand harsh outdoor environments and stresses while providing high anchorage to elastomeric substrates, such as car tires, for a long service life.

Surfacing films and related processes are provided. These films include a first clear coat layer comprising a first crosslinked polyurethane that is the reaction product of an isocyanate; a polyol selected from the group consisting of: a caprolactone polyol, polycarbonate polyol, a polyester polyol, acrylic polyol, polyether polyol, polyolefin polyol, and mixtures thereof; and a hydroxy-functional silicone poly(meth)acrylate; a second clear coat layer comprising a crosslinked polymer that is essentially free of hydroxy-functional silicone poly(meth)acrylate; a bulk layer comprising a thermoplastic polyurethane; and an adhesive layer. The provided films overcome the problem of migration of solvents and other impurities into the polyurethane bulk layer because the clear coat layer is cured, and solvents removed, prior to the coating of the polyurethane bulk layer. Manufacturing of these films can provide substantially faster line speeds and reduced waste.
