Abstract

Una partícula encapsulada comprende una partícula de núcleo y una capa de poliuretano dispuesta alrededor de la partícula de núcleo. La partícula de núcleo puede ser de varias partículas, tales como fertilizantes, biocidas, retardadores de flama, semillas, etc. La capa de poliuretano comprende el producto de reacción de un componente isocianato y un componente reactivo con isocianato. El componente reactivo con isocianato comprende un poliol de injerto que tiene una fase continua y partículas poliméricas. Un método para formar una partícula encapsulada comprende los pasos de proveer la partícula de núcleo, aplicando el isocianato y componentes reactivos con isocianato a la partícula de núcleo y reaccionado el isocianato y componentes reactivos con isocianato para formar la capa de poliuretano. La partícula encapsulada tiene excelentes propiedades físicas, tales como repelencia al agua incrementada, resiliencia y vida de anaquel.
