Abstract

HASTA AHORA NO ERA POSIBLE PRODUCIR BARNICES AL FUEGO PUR MONOCOMPONENTES CON CUALIDADES APROVECHABLES USANDO POLIISOCIANATOS SEMIBLOQUEADOS, YA QUE ESTOS PRODUCTOS SEMIBLOQUEADOS CONTENIAN GRANDES CANTIDADES DE POLIISOCIANATO MONOMERO Y, EN ESPECIAL, DE PRODUCTOS TOTALMENTE BLOQUEADOS. TAREA DE LA PATENTE ERA APLICAR UN POLIISOCIANATO SEMIBLOQUEADO ADECUADO PARA LACAS PUR QUE ESTUVIERA MAYORMENTE LIBRE DE PRODUCTO MONOMERO Y TOTALMENTE BNLOQUEADO. LA TAREA SE SOLUCIONO REACCIONANDO PARA EL BARNIZ AL FUEGO PUR MONOCOMPONENTE COMPUESTOS DE POLIOXI CON POLIISOCIANATOS SEMIBLOQUEADOS, QUE TIENEN UN PORCENTAJE DEL PESO POR DEBAJO DE 10% DE NCO LIBRE Y SOLO UNA PEQUEÑA PARTE DE MONOMEROS DE POLIISOCIANATO. LOS POLIISOCIANATOS SEMIBLOQUEADOS USADOS SE CONVIERTEN EN LA REACCION DE MEDIOS DE BLOQUEO EN POLIISOCIANATOS EXCEDENTES.
