Abstract
Hydrophilic coating compositions and methods to make and use the compositions are disclosed. The compositions include a photocatalytic pigment material made up of an inorganic pigment and a monomeric anti-oxidants and free radical scavenger that is contacted to the surface of the inorganic pigment.
Claims38
A photocatalytic pigment material comprising:
- at least one inorganic pigment;
- and
- at least one monomeric anti-oxidant,
- wherein the anti-oxidant is contacted to the surface of the inorganic pigment, and
- wherein the photocatalytic pigment material provides a renewable hydrophilic and self-cleaning surface when applied on a substrate.
