CONDITIONING AGENT FOR GRANULATED FERTILIZER, REDUCING HYGROSCOPICITY AND DUST FORMATION Russian patent published in 2018 - IPC C05G3/00 B01J2/30 

FIELD: agriculture.

SUBSTANCE: inventions relate to agriculture. Conditioning agent for reducing water absorption and dust formation by the granular fertilizer contains from 10 to 50 % by weight of wax, 40 to 90 % by weight of mineral oil and from 1 to 15 % by weight of resin, which is soluble in mineral oil and mixed with wax and mineral oil, the agent further comprising 0.1 to 1 % by weight of a viscoelastic elastomer selected from the group of polyisobutylene and a styrene-isoprene-styrene block copolymer soluble in mineral oil and having an average molecular weight of from 30,000 to 5,000,000. Granular fertilizer composition comprises a granular substrate and from 0.05 to 2 % by weight of a coating containing a conditioning agent. Method for producing a conditioning agent.

EFFECT: invention makes it possible to obtain a conditioning agent that reduces dust formation, moisture absorption, is convenient for use in the temperature and humidity conditions existing in tropical and subtropical regions, and also a composition that minimizes sintering and dust formation under the same conditions.
