AI Technical Summary
Existing fluoropolyether-containing polymers used for forming coatings on touch panels and other displays suffer from poor abrasion durability, particularly when subjected to eraser abrasion, despite exhibiting high water/oil repellency and initial anti-fouling performance.
A fluoropolyether-containing polymer with a hydroxy-containing silyl group or hydrolyzable silyl group, represented by a specific general formula, is used to create a surface treating agent that forms a cured coating with improved water/oil repellency and eraser abrasion resistance.
The proposed solution enhances substrate adhesion and wettability, resulting in coatings that maintain excellent water/oil repellency and exhibit improved abrasion resistance, specifically against eraser abrasion, compared to previous technologies.
