The present invention provides a water processing film fitted on one side of the base film with a pressure-sensitive adhesive layer and further with a release film on the surface of the pressure-sensitive adhesive layer, and coated on the back side of the base film a phosphoric surfactant wherein ionic components are not detected by ion chromatography, and can prevent failure of an integrated circuit dye static electricity generated in the handling of the wafer processing film and can also inhibit contamination and corrosion of the wafer by surfactant.
摘要:
The release-coating composition for producing a pressure-sensitive, printable adhesive tape is constituted by a polymeric component comprising from 10 to 85 parts by weight of a ketone resin, from 0 to 80 parts by weight of a polyamide resin and from 0 to 30 parts by weight of a ketone resin modified by reaction with alkylisocyanates, and solvents for the polymeric component. For the production of a printed adhesive tape, there is used, in combination with said release-coating composition, an ink comprising, with reference to the weight of the ink form 25% to 35% by weight of a polyamide resin which is soluble in alcohols and from 0.3% to 1% by weight of a silicone polymer as a slip agent.

摘要:
A release liner having a generally flat first substrate, with a first side and a second side. The first side includes a first coating, providing release against a pressure-sensitive adhesive, when that pressure sensitive adhesive is contacted with the first side. The release liner also includes a. second, preferably solvent-free, curable coating for application to the second side of the release liner. That coating comprises a mixture, the mixture having two pre-polymer components, the first pre-polymer component comprising at least one monomer, and the second pre-polymer component comprising either (a) at least one oligomer or (b) at least one soluble resin. The coating further comprises insoluble non-mineral type particles within that mixture. The insoluble non-mineral type particles preferably comprise an insoluble polymer powder, and most preferably an insoluble polyamide powder.
摘要:
The present invention relates to the manufacturing of adhesive tapes having a backing consisting of a polypropylene or other olefinic polymer or copolymer film, one side of which is coated by elastomeric or plastomeric adhesive systems (as applied from solutions, emulsions, in a molted condition, etc., according to the technologies known in the art), the other side being coated with or without corona or flame treatment, with antiadhesive systems which facilitate the unwinding operation of the tape either in the processing and in the application, but at the same time may receive printing inks of the flexoroto-silk-screen type inks suitable for the printing of polyolefinic films. The application of antiadhesive systems which are ink compatible can be carried out either on line, namely during the tape coating process, and on tapes already coated by means of the duly modified printing machine. In some cases there is foreseen the application, immediately after the printing process, of an additional antiadhesive layer to facilitate the unwinding operation and application of the printed tapes.
