<p>A super hydrophobic self-cleaning coating composition composed of from 0.001 to 5% by weight of hydrophobic fumed silicas coated in 95% to 99.999% by weight of a solvent, preferably acetone, to form a super hydrophobic coating for forming an almost clear, translucent dirt repellant film on a painted material, plastic, metal, glass, ceramic, fiberglass, wood, waxed or polymer substrate. The treated fumed silica in a solvent forms a film having a contact angle of at least 165 degrees as compared to water having a contact angle of from 50 to 60 degrees on a noncoated surface. The composition imparts a degree of hydrophobicity to the surface so that the surface has a tilt angle of sliding of less than 2 degrees as compared to water on a noncoated surface having a tilt angle of sliding of 90 degrees or higher.</p> |
