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

摘要

The invention relates to an intrinsically viscous clear powder coating slurry which is free of organic solvents and external emulsifiers and which contains solid spherical particles with an average particle size of 0.8 to 20 mu m and a maximum particle size of 30 mu m, at least one ionic thickener and at least one non-ionic associative thickener. The clear powder coating slurry contains 0,05 to 1 meq/g of ion-forming groups and 0.05 to 1 meq/g neutralising agents and has a viscosity of (i) 50 to 1000 mPas at a shear rate of 1000 s-1, (ii) 150 to 8000 mPas at a shear rate of 10 s-1 and (iii) 180 to 12000 mPas at a shear rate of 1 s-1.
