Patent ID: 7041729

Claim:
A pseudoplastic powder clearcoat slurry free from organic solvents and external emulsifiers, comprising particles which are dimensionally stable under storage and application conditions, the particles having an average size of from 1.0 to 20 μm and a particle size distribution wherein at least 99% of the particles have a size <30 μm, and a binder, said binder comprising at least one polyol comprising ion-forming groups convertible into salt groups by neutralization and an OH number of from 130 mg KOH/g to 160 mg KOH/g, wherein said pseudoplastic powder clearcoat slurry 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 and comprises from 0.01 to 1 meq/g of solids of ion-forming groups convertible into salt groups by neutralization, and from 0.005 to 0.1 meq/g of solids of ionic groups produced by neutralization of the ion-forming group at not more than 50% neutralization.
