Abstract

La presente invencion se refiere a ductos de poliisocianato que contienen, grupos alofanato, grupos siloxano y opcionalmente grupos isocianurato que se preparan reaccionando compuestos a) que i) están sustancialmente libres de grupos hidroxilo y grupos isocianato, ii) tiene un promedio de al menos dos grupos uretano por molécula y iii) contienen de 0 a 50% en peso de grupos siloxano, en base al peso de los aductos de poliisocianato, con una cantidad excesiva, basada en los equivalentes de grupos uretano, de poliisocianatos b), que contienen opcionalmente grupos siloxano, para formar aductos de poliisocianato y eliminando opcionalmente al menos un porcion de los poliisocianatos excesivos sin reaccionar b), a condicion de que los compuestos a) y los poliisocianatos b) contengan un total de al menos 0,001% en peso de grupos siloxano en base al peso de los aductos de poliisocianato. La presente invencion también se refiere a un procedimiento para preparar dichos aductos de poliisocianatos, a mezclas de los poliisocianatos con otros poliisocianatos que no contienen grupos siloxano y al uso de los aductos de poliisocianato o mezclas de poliisocianato, opcionalmente en forma bloqueada, en composiciones de recubrimiento de uno o dos componentes.
