  • Patent number: 8961672
    Abstract: Solid alkali metal salts of organosilanols and/or their hydrolysis/condensation products are prepared by hydrolysis of organosilanes in water and in the presence of a basic alkali metal salt. The products contain predominately methyl and ethyl organic groups, and C4 or higher hydrocarbon groups as well. The solid salts effectively hydrophobe building materials, while being easily mixed with water.

  • Patent number: 8961671
    Abstract: A super hydrophobic and antistatic brake dust repellent composition using solvents, adhesion promoter, and hydrophobic inorganic nano particles as a main ingredient is provided. Embodiments of the inventive formulation provide a composition/coating, and a process for protecting various surfaces from the appearance of soil, brake dust, grime, muddy water marks, and corrosion. The applied formulation forms an essentially transparent, detachable, and anti-graffiti protective coating on a receptive surface. Embodiments of the coating film are clearly transparent, and retain the aesthetic appeal of the underneath painted film. The composition/coating acts as a self-cleaning coating so it reduces a adsorption of dirt, other contaminants, muddy water, etc. The coating can be applied at room temperature, and within 120 minutes super hydrophobicity can be achieved.
