Definitions
- the object of the invention is therefore to develop a method which makes it possible to produce powders which have a good “maintenance behavior”.
- it In addition to the known advantages of being dust-free, it must also be characterized by good blocking behavior and good redispersibility.
- Examples 1 and 2 represent comparative examples, thus explaining the prior art and are not according to the invention.
- the polymer from Tab 1 was sprayed in accordance with DE 2214410 in emulsion form with the antiblocking agent mixture listed. The result was a free-flowing, redispersible powder with good blocking behavior. The redispersibility of the powder was judged to be very good based on the inconsistency. In the "instant" test, however, it turned out to be completely inadequate and had to be rated 5.
