AHA6640 es un endurecedor para poli\u00e9ster con terminaci\u00f3n OH para lograr recubrimientos en polvo decorativos resistentes a la intemperie con excelentes propiedades f\u00edsicas. (NCO: OH=1:1) se recomienda para obtener propiedades \u00f3ptimas de la pel\u00edcula. Dependiendo de los correactivos utilizados y de las propiedades de la pel\u00edcula requeridas, es posible una ligera sub-reticulaci\u00f3n (NCO: OH=0,8:1).
Ciclo de curado: 20 minutos a 180\u00b0C o 10 minutos a 200\u00b0C<\/p>\n\n\n\n

Proceso y formulaciones<\/strong><\/h2>\n\n\n\n

Se a\u00f1ade AHA6640 a la mezcla de aglutinante\/pigmento antes de la extrusi\u00f3n.
