CURABLE PERFLUOROPOLYETHER ADHESIVE COMPOSITION, AND ADHESIVE AND ADHESIVE TAPE USING CURED PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/196355
Kind Code:
A1
Abstract:
The present invention pertains to a curable perfluoropolyether adhesive composition that contains: (A) 100 parts by mass of a straight-chain perfluoropolyether compound that has at least two alkenyl groups in one molecule, and that has, in the main chain, a perfluoropolyether structure including a repeating unit represented by —CaF2aO— (where a is an integer from 1-6); (B) in an amount effective for curing, a fluorine-containing organohydrogenpolysiloxane having, in one molecule, at least two hydrogen atoms to which a silicon atom is bonded; and (C) a catalyzing quantity of a hydrosilylation reaction catalyst. The composition does not contain an organic solvent. This configuration makes it possible to provide: a curable perfluoropolyether adhesive composition with which can be achieved a cured product that has excellent heat resistance, weather resistance, water repellency, oil repellency, chemical resistance, solvent resistance, etc., and that is characterized in particular in that voids are not generated on the surface of a coating film in a heating step; and an adhesive and adhesive tape that include said cured product.
