Isbarn Gunther Dr, Fauth Karl Heinz Dr, Kolk Erich Dr, Gropper Hans Dr: The use of micronized polyethylene wax as parting agent for tacky granulates.. BASF, December 29, 1993: EP0575900-A1 (3 worldwide citation)

Micronised polyethylene wax having a mean particle size of from 1 to 30 mu m is suitable as an antitack agent for detackifying the surface of tacky granules. The micronised polyethylene wax develops its action here even in the small amounts of from 0.01 to 2% by weight, based on the granules. Partic ...
