Abstract:
There is provided a radiation-curable adhesive tape comprising a radiation-curable adhesive layer which is formed on a radiation transmitting substrate. The radiation-curable adhesive layer is composed of an acrylic adhesive and radiation-curable compound having carbon-carbon double bonds. The radiation-curable tape can be used preferably in processing steps for the production of semiconductor wafer, ceramics and glass employing a direct picking-up system.
Abstract:
An adhesive tape is described, which is destroyed by delamination upon removal from a substrate but which may be unwound from a supply roll without destruction. The adhesive tape comprises an inner layer of a polyolefin having 2 to 6 carbon atoms containing in a finely distributed form solid organic particles with a size of from about 0.2 to 20 microns and polyolefin cover layers on both sides of the inner layer, one of which is coated with an adhesive and the other with a release coat.
Abstract:
A self-sticking adhesive tape is provided which is particularly effective for joining free ends of a photoconductive belt at a side of the belt presenting a photoconductive layer of ZnO dispersed in a binding agent. The tape comprises a polyester support film provided on one side with a flexible electrically conductive layer to prevent retention of electrostatic charges and provided on the other side with an adhesive layer, made sticky preferably by an acrylate resin, having (a) an adhesive force of at least 200 Newton per meter and (b) a shear tolerance of not more than 1 mm, as determined by tests of the tape after its adhesive side has been adhered to such photoconductive layer. The conductive layer preferably consists essentially of a dispersion of carbon particles in a polymeric binder such as 60:40 copolymer of ethylene-terephthalate and ethylene-isophthalate, and the adhesive layer of a dried coating of an anionic dispersion in water of a finely divided acrylic ester containing carboxyl groups.
Abstract:
Chemically-resistant adhesives formed using non-hydrolyzable hard and soft resins. Chemically-resistant labels are provided by using the adhesive to adhere an image-bearing film of polyvinyl chloride to a protective film, and to a carrier. The labels are particularly resistant to acids and have a reduced tendency to shrink or distort when affixed to battery surfaces at elevated temperatures.
Abstract:
A security film for shatter-proofing windows comprises a polyurethane stratum interposed between a pair of polyester strata, each of which is self supporting, the film being bonded to the inner face of the window by a pressure sensitive adhesive.
Abstract:
This invention pertains to an adhesive tape, the base component of which is comprised of a biaxially oriented film of a propylene polymer and a transversely oriented film of a propylene polymer, the melting point of the transversely oriented film being 0.5* 10*C higher than that of the biaxially oriented film and the total thickness of the transversely oriented film being 1.2 - 5.0 times greater than that of the biaxially oriented film.
Abstract:
An integral heat-set, biaxially oriented composite film comprised of a layer of transparent polyethylene terephthalate having a smooth exposed major surface and a transparent copolyester layer having a matte exposed major surface. The film is dimensionally stable, strong, tough and water resistant, receptive to writing, and transparent when applied to a substrate, permitting visual recognition of indicia therethrough. The film provides a particularly superior backing for an adhesive tape.
Abstract:
A protective tape that improves solder bonding properties and reduces wafer warping. The protective tape includes, in the following order, an adhesive agent layer, a first thermoplastic resin layer, a second thermoplastic resin layer, and a matrix film layer. The protective tape satisfies the conditions expressed by the following formulae (1) to (3): Ga>Gb (1) Ta
Abstract:
A multilayer adhesive film comprising surface adhesive layers, an internal Controlled Bond Layer (“CBL”) comprising a propylene-based polymer strippably adhered to an adjacent layer; an internal Strong Bond Layer (“SBL”) different than the CBL having a facial surface in adhering contact to the CBL and; optionally, one or more different internal Filler Layer(s) located between the SBL and the adhesive surface layer on the side of the SBL opposite to the adhered CBL. In preferred embodiments the adhesive comprises an ethylene/ethylenically unsaturated carboxylic acid copolymer. The adhesive films are used in cable shielding structures.
Abstract:
Provided is a thermoplastic resin film comprising a base layer (A) containing a thermoplastic resin and a coating layer (B) provided on at least one surface of the base layer (A), the coating layer (B) containing components derived from (a) an emulsion containing resin particles formed from an olefin-based copolymer and (b) an ethyleneimine-based resin, wherein the thermoplastic resin film is characterized in that a volume-average particle size of the resin particles contained in the emulsion is from 0.1 to 0.72 μm. The thermoplastic resin film has good coloring performance during printing using gold ink and/or silver ink, has conventional transferability and adhesiveness even in hot melt transfer, and shows little generation of paper dust.
