Abstract
Las resinas de amino, que contienen más formaldehído libre del deseado por razones de salud y/o contaminacion, se pueden tratar con una mezcla de reactivos de diceto (o sus análogos de nitrogeno) y otros compuestos que contienen parte de amino, para reducir el contenido del formaldehído libre, mientras no disminuyen, y en algunos casos aun mejoran, la capacidad de las resinas para funcionar de acuerdo con sus usos normales. La invencion es especialmente util para las dispersiones de resina de melamina formaldehído, utiles como agentes que remueven la pegajosidad en las pinturas.
