Abstract

La presente invencion se refiere a poliisocianatos que contienen: i) de 0.5 a 10% en peso de unidades estructurales de amida y/o imida (calculadas como -CO-N=,p.m. = 42, ii) de 5 a 20% en peso de grupos isocianato (calculados como -NCO, p.m. = 42) bloqueados con agentes bloqueadores que son monofuncionales en el contexto de la reaccion de adicion de isocianato y iii) de 0 a 30% en peso de grupos uretano químicamente incorporados (calculados como -NH-CO-O-, p.m. = 59), obtenidos a partir de la reaccion de grupos isocianato con los grupos hidroxilo de compuestos orgánicos de polihidroxilo. La presente invencion también se refiere a un proceso para la produccion de estos poliisocianatos para laca, a su uso como aglutinantes para lacas horneadas, opcionalmente en combinacion con compuestos orgánicos de polihidroxilo, y a su uso como componente aglutinante que contiene grupos hidroxilo libres y opcionalmente grupos isocianato bloqueados, mediante la reaccion y/o mezcla de los poliisocianatos con compuestos orgánicos de polihidroxilo que tienen un peso molecular de 62 a 350.
