  • Powder-slurry that can be hardened by actinic radiation or optionally by thermal means, method for producing said slurry and use of the same
    Patent number: 6747091
    Abstract: The invention relates to an intrinsically viscous powder-slurry that can hardened by actinic radiation or optionally by thermal means, which contains solid spherical particles with an average particle size of 0.8 to 20 &mgr;m and a maximum particle size of 30 &mgr;m. The clear powder coating slurry contains 0.05 to 1 meq/g of ion-forming groups and 0.05 to 1 meq/g of neutralizing 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) from 180 to 12000 mPas at a shear rate of 1 s−1.
