Superhydrophilic Coating Composition

摘要

A composition for forming a hydrophilic coating includes an organic binder having an average particle size from about 1 to about 100 nm and an inorganic binder having an average particle size from about 1 to about 40 nm. The composition further includes an inorganic photocatalyst that catalyzes an oxidation-reduction reaction. Characteristically, the photocatalyst includes a photocatalytic metal oxide having an average particle size from about 1 to about 50 nm. Advantageously, coatings formed from the composition have improved stain resistance, low contact angle, and resistance to dirt adherence, while maintaining a clear optical character.

1. A composition for forming a hydrophilic coating comprising:
water in an amount from about 0 to 95 percent of the total weight of the composition; an organic binder having an average particle size from about 1 to about 100 nm; an inorganic binder having an average particle size from about 1 to about 40 nm; and an inorganic photocatalyst that catalyzes an oxidation-reduction reaction, the photocatalyst including a photocatalytic metal oxide having an average particle size from about 1 to about 50 nm.
