CURABLE PERFLUOROPOLYETHER ADHESIVE COMPOSITION, AND ADHESIVE AGENT AND ADHESIVE TAPE USING CURED PRODUCT OF SAME
Document Type and Number:
WIPO Patent Application WO/2021/124824
Kind Code:
A1
Abstract:
The present invention is a curable perfluoropolyether adhesive composition which contains components (A) to (C): (A) 100 parts by mass of a linear perfluoropolyether compound having a perfluoropolyether structure which has at least 2 alkenyl groups per molecule and which includes a repeating unit represented by -CaF2aO- in te main chain (a being an integer from 1 to 6); (B) an effective curing amount of an organosilicon compound having at least 2 silicon atom-bonded hydrogen atoms per molecule; and (C) a catalytic amount of a hydrosilylation reaction catalyst. When cured, the curable perfluoropolyether adhesive composition forms an adhesive agent having an adhesive strength of less than 0.5 N/25 mm. Thus, it is possible to provide a curable perfluoropolyether adhesive composition that gives a cured product which exhibits excellent heat resistance, weathering resistance, water repellency, oil repellency, chemical resistance and solvent resistance, and which is characterized by being slightly adhesive.
