Waterborne Liquid-like Coatings with High Transparency, Superior Scratch Resistance, and Antismudge Properties.

The aqueous formulation of antismudge coatings is a crucial step for environmental protection and pollution reduction. However, the inferior mechanical durability of waterborne antismudge coatings poses challenges for their practical application. Herein, we developed a fully waterborne antismudge coating with excellent scratch resistance by preparing hyperbranched amine-rich polysiloxane (HSP) for antismudge ability and epoxy-rich zirconium-based aqueous solution (ZAS) for mechanical performance.
