Abstract

COMPOSICIONES CATALIZADORAS NOVEDOSAS QUE INCLUYEN COMPLEJOS DE SALES DE ESTAÑO (IV) Y COMPUESTOS AMINOS QUE SE UTILIZAN PARA PREPARAR POLIURETANOS, POLIUREAS, POLICARBODIIMIDAS Y POLIISOCIANURATOS. LOS COMPLEJOS, QUE EMPLEAN PREFERIBLEMENTE AMINAS PRIMARIAS, PERMITEN EL RETRASO DE LA GELACION HASTA QUE SE DESASOCIAN BAJO CONDICIONES DE REACCION ESPECIFICAS. LOS COMPLEJOS PUEDEN PREPARARSE SOLOS, O IN SITU EN UNHIDROGENO ACTIVO QUE CONTIENE UN COMPONENTE DE FORMULACION. LOS COMPLEJOS SIRVEN PARA RETRASAR LA GELACION DE LA FORMULACION PORQUE SON RELATIVAMENTE ESTABLES A LA HUMEDAD Y SE DESASOCIARAN PREDECIBLEMENTE AL CALENTARSE, BIEN COMO RESULTADO DE LA NATURALEZA EXOTERMICA DE LA REACCION QUE ESTA SIENDO CATALIZADA, O CON LA APLICACION DE UNA FUENTE DE CALOR EXTERNA. LAS COMPOSICIONES CATALIZADORAS SON PARTICULARMENTE UTILES PARA LA PREPARACION DE LOS REVESTIMIENTOS DE MOQUETAS Y OTRAS APLICACIONES QUE REQUIERAN UN RETRASO IMPORTANTE ANTES DE LA GELACION.
