CURABLE PERFLUOROPOLYETHER PRESSURE-SENSITIVE ADHESIVE COMPOSITION, AND PRESSURE-SENSITIVE ADHESIVE AND PRESSURE-SENSITIVE ADHESIVE TAPE BOTH INCLUDING CURED OBJECT FORMED THEREFROM

WIPO Patent Application WO/2024/080218

A1

The present invention relates to a curable perfluoropolyether pressure-sensitive adhesive composition comprising: 100 parts by mass of (A) a linear perfluoropolyether compound having at least two alkenyl groups in the molecule and having, in the main chain, a perfluoropolyether structure containing a repeating unit represented by -CaF2aO- (wherein a indicates an integer of 1-6); a curing-effective amount of (B) an organosilicon compound having at least two silicon-atom-bonded hydrogen atoms in the molecule; a catalytic amount of (C) a hydrosilylation catalyst; and an effective amount of (D) an antistatic agent. This curable perfluoropolyether pressure-sensitive adhesive composition forms a pressure-sensitive adhesive which is a cured object excellent in terms of heat resistance, weatherability, water repellency, oil repellency, chemical resistance, solvent resistance, etc. and which especially can be prevented from causing static buildup when an adherend adherent thereto is removed or when a tape coated therewith is peeled off. Also provided are a pressure-sensitive adhesive and a pressure-sensitive adhesive tape which include the cured object formed from the composition.
