Abstract: A paint composition for forming energy saving self-cleaning coatings includes water, a binder composition, a powder catalyst composition, a first pigment composition, a second pigment composition, and a fluoropolymer-composition. The binder composition includes a first acrylic resin having an average particle size from about 0.2 to 1 micron and a glass transition temperature less than about 10° C. The powder catalyst composition includes anatase titanium dioxide with a surface area from about 50 to 500 m2/g. It should be appreciated that anatase provides catalyst activity that is useful for providing the self-cleaning properties of the present embodiment. The first pigment composition includes rutile titanium dioxide which typically has low or no catalytic activity while the second pigment composition is different than the first pigment composition. Characteristically, the fluoropolymer-containing composition includes polyvinylidene fluoride and a second acrylic resin.
