Abstract

LA PRESENTE INVENCION DESCRIBE UN FERTILIZANTE GRANULAR DE LIBERACION LENTA DE UREA CUBIERTA CON AZUFRE QUE TIENE UNA CUBIERTA POLIMERICA DURADERA, UNIFORME SOBRE LA CUBIERTA DE AZUFRE. LA CUBIERTA DEL POLIMERO SE FORMA MEDIANTE LA COPOLIMERIZACION DIRECTA IN SITU DE POLIOL DE TRIETANOLAMINA DE DIETILENGLICOL Y UN DIISOCIANATO EN LA SUPERFICIE DEL GRANULO DE UREA CUBIERTO CON AZUFRE. LA CUBIERTA POLIMERICA PROPORCIONA RESISTENCIA AL IMPACTO MEJORADA DEL GRANULO CUBIERTO DE COMPOSITE.
