Pseudoplastic, of organic solvents and external emulsifiers free powder clearcoat - slurry, to a process for their preparation and their use

摘要

A pseudoplastic powder clearcoat slurry which is free from organic solvents and external emulsifiers and comprises solid spherical particles with an average size of from 0.8 to 20 mum and a maximum size of 30 mum, at least one ionic thickener and at least one nonionic associative thickener, the powder clearcoat slurry having an ion-forming group content of from 0.05 to 1 meq/g, a neutralizing agent content of from 0.05 to 1 meq/g, and a viscosity of (i) from 50 to 1 500 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.
