Abstract

LA INVENCION TRATA DE POLIISOCIANATOS BLOQUEADOS CON ESTER MALONICO, QUE ESTAN ESTABILIZADOS CON FORMALDEHIDO CONTRA EL AMARILLEAMIENTO TERMICO. ES CONOCIDO HACE TIEMPO EL ESTER MALONICO COMO BLOQUEANTE DEL ISOCIANATO (LIEBIGS AN. CHEM. 562 (1949) PAGINA 205 Y SIGUIENTES). UNA VARIANTE NUEVA ESPECIAL DE ESTE TIPO DE BLOQUEADO SE DESCRIBE POR EJEMPLO EN LA EP-A 600 314. LAS VENTAJAS DEL RETICULANTE BLOQUEADO DE POLIISOCIANATO CON LOS ESTERES ACIDOS DE CH ESTAN EN QUE SE CONSIGUE CON ELLOS TEMPERATURAS DE RETICULACION DE APROXIMADAMENTE UNOS 100 C, Y QUE ESTOS AGENTES BLOQUEANTES SON MAS FACILMENTE MANEJABLES EN LA INDUSTRIA.
