Abstract

Patente de Invenção: <B>"óXIDOS METáLICOS COLOIDAIS APRESENTANDO GRUPOS DE ISOCIANATO BLOQUEADOS"<D>. A presente invenção refere-se a óxidos metálicos coloidais apresentando grupos de isocianato bloqueados, que são baseados no produto de reação de A) silanos contendo grupos de isocianato bloqueados correspondendo à fórmula (I) em que R representa hidrogênio ou um grupo orgânico apresentando de 1 a 40 átomos de carbono, X, Y e Z representam grupos orgânicos idênticos ou diferentes apresentando de 1 a 30 átomos de carbono que são inertes aos grupos de isocianato abaixo de 100‹C, estabelecido que pelo menos um desses grupos é um grupo C~ 1~-C~ 4~ alcóxi, Q representa um grupo orgânico que contém pelo menos um grupo isocianato reagido com um agente de bloqueio e n é 2, 3 ou 4 com B) óxidos metálicos coloidais selecionados a partir de Al, Si, Ti, Ta, W, Hf, Zr, Sn e Y. A presente invenção refere-se também ao uso de óxidos metálicos modificados, sozinhos ou em combinação com compostos contendo pelo menos dois grupos reativos de isocianato, para a preparação de agentes de revestimento, lacas ou plásticos de poliuretano opcionalmente expandidos.
