Document Type and Number:
WIPO Patent Application WO/2021/117488
Kind Code:
A1
Abstract:
The present invention is a curable perfluoropolyether adhesive composition comprising: (A) 100 parts by mass of a linear perfluoropolyether compound having at least two alkenyl groups in one molecule, and having a perfluoropolyether structure containing a repeating unit represented by -CaF2aO- in a main chain; (B) an organosilicon compound having at least two hydrogen atoms bonded to a silicon atom in one molecule; (C) a hydrosilylation reaction catalyst; and (D) 0.05-5 parts by mass of an organosilicon compound which is not the (B) component and has at least two selected from a hydrogen atom bonded to a silicon atom in one molecule, an epoxy group bonded to a carbon atom or a silicon atom via a carbon atom and an oxygen atom, and a trialkoxysilyl group bonded to a carbon atom or a silicon atom via a carbon atom and an oxygen atom. Consequently, it is possible provide a curable perfluoropolyether adhesive composition from which a rubber-like or gel-like cured product closely adhering to a substrate is formed.
