Document Type and Number:
WIPO Patent Application WO/2023/199768
Kind Code:
A1
Abstract:
A surface treatment agent according to the present invention comprises a fluoropolyether group-containing polymer, which is a high molecular polymer having a number-average molecular weight of a fluorooxyalkylene group-containing polymer residue in the main chain of 6,000-30,000, has a silanol group or a hydrolyzable silyl group at both ends of the molecular chain, and has a siloxane structure in a linking group of the fluorooxyalkylene group-containing polymer residue in the main chain and the silanol group or the hydrolyzable silyl group at both ends of the molecular chain, and/or a partial (hydrolyzed) condensate thereof. The surface treatment agent can form a cured coating film having excellent water-repellency and oil-repellency, abrasion resistance, and chucking properties.
