  • Process for producing dispersible powders
    Patent number: 9051440
    Abstract: A process for producing dispersible powders by spray-drying aqueous polymer dispersions and adding antiblocking agent, wherein antiblocking agents present in agglomerated form and having a particle size from 10 ?m to 250 ?m, or having a particle size from 5 mm to 5 cm in the case of agglomerates in the form of extrudates, are fed in whole or in part by a transport gas into the spray-drying device and are comminuted to a particle size from 0.01 ?m to 5 ?m, or, in the case of extrudates, to a particle size from 2 ?m to 60 ?m.
    Type: Grant
    Filed: July 23, 2012
    Date of Patent: June 9, 2015
    Assignee: WACKER CHEMIE AG
    Inventors: Michael Herbert, Jochen Ring, Stefan Killat, Bernd Gerstenberger
  • Process for producing dispersion powders
    Patent number: 8984765
    Abstract: A process for producing dispersion powders by spray drying of aqueous polymer dispersions and addition of antiblocking agents in a rotary atomization dryer, wherein the antiblocking agent is conveyed by delivery air, wholly or partly, into an annular gap which is formed by a moulding arranged concentrically around the housing of the rotary atomizer, and which ends at a distance above the upper edge of the atomizer plate of the rotary atomizer.
