Anti-caking treatment for fertilizers in order to avoid dust emissions during storage

The use of a mixture of dialkyl secondary monoamines and primary alkylamines, the weight of primary amines being at most 75% and the alkyl groups having 14-20 C atoms, optionally with oils, waxes, mineral powders, anionic surfactants, and other formulation ingredients, to coat granular ternary ferti...

More Information
Summary:The use of a mixture of dialkyl secondary monoamines and primary alkylamines, the weight of primary amines being at most 75% and the alkyl groups having 14-20 C atoms, optionally with oils, waxes, mineral powders, anionic surfactants, and other formulation ingredients, to coat granular ternary fertilisers, is new. Des compositions de traitement d'engrais granulaires comportant des monoamines secondaires dialkyles en C14/C20 ou leur mélange avec des monoamines primaires également en C14/C20 présentent l'avantage de limiter à la fois la prise en masse et l'émission secondaire de poussières au stockage. Le procédé est particulièrement intéressant pour le traitement des engrais de type NPK.
