Title:
FLUOROPOLYETHER GROUP-CONTAINING POLYMER COMPOSITION, COATING AGENT, ARTICLE, AND METHOD FOR MODIFYING SURFACE OF ARTICLE
Document Type and Number:
WIPO Patent Application WO/2024/075578
Kind Code:
A1
Abstract:
Provided is a coating agent comprising a fluoropolyether group-containing polymer composition that contains, at a specific ratio: a polymer and/or a partial (hydrolyzed) condensate (I) thereof, the polymer having a fluorooxyalkyl group at one end thereof, and at least two reactive functional groups at the other end thereof; and a polymer and/or a partial (hydrolyzed) condensate (II) thereof, the polymer having a fluorooxyalkylene group in a molecule, and a reactive functional group bonded to both ends of the fluorooxyalkylene group via a linking group that does not have a polar group. By using the coating agent, a cured film can be formed that has excellent water and oil repellency, and abrasion durability, and that maintains high abrasion durability even after surface cleaning.
