Abstract
La presente invencion se refiere a aductos de poliisocianatos que contienen grupos alofanato, fluor y opcionalmente grupos isocianurato que se preparan reaccionando compuestos a) que i) están sustancialmente libres de grupos hidroxilo y grupos isocianato, ii) tienen un promedio de al menos dos grupos uretano por molécula y iii) contienen de 0 a 50% en peso de fluor, 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 fluor, para formar aductos de poliisocianato y eliminando opcionalmente al menos una 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 fluor 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 aductos de poliisocianatos con otros poliisocianatos que no contienen fluor y al uso de los aductos de poliisocianato o mezclas de poliisocianatos, opcionalmente en forma bloqueada, en composiciones de recubrimiento de uno o dos componentes.
