Abstract

PROCEDIMIENTO PARA PREPARAR COMPUESTOS HIDROFOBOS, QUE TIENEN MATERIAL DE NUCLEO, PRIMER REVESTIMIENTO ADHERENTE Y SEGUNDO REVESTIMIENTO HIDROFOBO DE OXIDO COLOIDAL. SE PREPARA UN COMPUESTO HIDROFOBO DEPOSITANDO, SOBRE UN NUCLEO DE MATERIAL FORMADO POR PARTICULAS O GRANULOS, UNA PRIMERA CAPA DE ADHESIVO, CONSTITUIDA POR POLIURETANO QUE FORMA UNA PELICULA Y A OPCION, ASFALTO, Y APLICANDO AL NUCLEO DE MATERIAL ASI REVESTIDO UN OXIDO COLOIDAL HIDROFOBO, TAL COMO SILICE HIDROFOBA AHUMADA. LOS COMPUESTOS RESULTAN MUY UTILES PARA DIVERSAS APLICACIONES IMPERMEABILIZANTES, ASI COMO PARA LIMPIAR DERRAMES DE PETROLEO.
