摘要： 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 μm, at least 99% of the particles having a size ≦30 μm, and comprise as binder at least one polyol with an OH number >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−1, (ii) from 150 to 8 000 mPas at a shear rate of 10 s−1, and (iii) from 180 to 12 000 mPas at a shear rate of 1 s−1.
