  • Dispersion comprising hydrophobized silicon dioxide particles, and paint preparation
    Patent number: 8882901
    Abstract: Aqueous dispersion comprising hydrophobized silicon dioxide particles, comprising a. 50%-80% by weight of water, b. 10%-30% by weight of hydrophobized silicon dioxide particles, c. 5%-15% by weight of at least one alcohol alkoxylate of the general formula R1O((CH2)mO)nH, where R1 is a branched or unbranched alkyl or alkenyl radical having 10-25 C atoms, m is 2 or 3 and n is 10-50, d. 0.5%-5% by weight of at least one amine and/or amino alcohol having a molecular weight of less than 500 and e. 0%-1% by weight of N-methylpyrrolidone, all figures for weight percentages being based on the dispersion. Paint formulation comprising the dispersion.
