A pseudoplastic clearcoat slurry comprising solid and/or highly viscous particles which are dimensionally stable under storage and application conditions and at least one wetting agent selected from the group consisting of alkoxylated fatty alcohols having from 16 to 18 carbon atoms in the alkyl radical and containing on average per molecule at least 20 oxaalkanediyl groups; process for preparing it, and its use.

Structurally viscose clear lacquer slurry, method for the production and use thereof

A pseudoplastic powder clearcoat slurry free from organic solvents and external emulsifiers and comprising particles which are solid and/or of high viscosity and are dimensionally stable under storage and application conditions, where the particles have an average size of from 1.0 to 20 &#x3bc;m, at least 99% of the particles having a size &#x2266;30 &#x3bc;m, and comprise as binder at least one polyol with an OH number &#x3e;110 mg KOH/g, containing potentially ionic groups, and where the powder clearcoat slurry has a potentially ionic group content of from 0.05 to 1 meq/g of solids, at a degree of neutralization of not more than 50% contains from 0.005 to 0.1 meq/g of solids of ionic groups produced by neutralization of the potentially ionic groups, and has a viscosity of (i) from 50 to 1 000 mPas at a shear rate of 1 000 s, (ii) from 150 to 8 000 mPas at a shear rate of 10 s, and (iii) from 180 to 12 000 mPas at a shear rate of 1 s.
