摘要： Lacquer formulations containing: from 5 to 99.5 wt. % of solids of a polymer component or of a mixture of two or more physically or chemically crosslinking polymer components, (binder components and hardener components), from 0 to 80 wt. % of a low molecular weight component acting as solvent or of a mixture of such low molecular weight components, from 0.5 to 50 wt. % of a silanised, structurally modified pyrogenic silica to the surface of which there are attached alkylsilyl groups (SiC n H 2n+1 , where n=from 2 to 18) and/or dimethylsilyl groups and/or monomethylsilyl groups, from 0 to 10 wt. % of commercially available additives.

摘要： 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 R
1 O((CH
2 )
m O)
n H, where R
1 is a branched or unbranched alkyl or alkenyl radical having 10-25 C atoms, m = 2 or 3 and n = 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 of the weight percentage figures being based on the dispersion. Paint preparation comprising the dispersion.
