Title (EN) PROCESS FOR PRODUCING IMPROVED SULFUR-COATED UREA SLOW RELEASE FERTILIZERS
(FR) PROCEDE DE FABRICATION D'ENGRAIS GRANULAIRES D'UREE A ENROBAGE DE SOUFRE AMELIORES
Abstract: front page image
(EN)The present invention describes a sulfur-coated urea slow release granular fertilizer having a uniform, durable polymeric coating over the sulfur-coating. The polymer coating is formed by the direct $i(in situ) co-polymerization of diethylene glycol-triethanolamine polyol and a diisocyanate on the surface of the sulfur-coated urea granule. The polymeric coating provides improved impact resistance of the composite coated granule.
(FR)L'invention porte sur des engrais granulaires d'urée à diffusion lente enrobés de soufre, dont l'enrobage de soufre est lui-même recouvert d'une couche durable d'un polymère qui confère aux granulés enrobés une résistance accrue à l'impact.
