Abstract
SE SOLIDIFICAN RESINAS DE AMINO POR EJEMPLO RESINAS TERMOESTABLES DE UREA ON UN CATALIZADOR LATENTE, QUE ES UN ADUCTO DESCOMPONIBLE TERMICAMENTE DE UN ACIDO SULFONICO AROMATICO (POR EJEMPLO ACIDO SULFONICO P OR EJEMPLO 1 ANO. LAS COMPOSICIONES DE REVESTIMIENTO PUEDEN CONTENER OTROS CO-REACTIVOS CONVENCIONALES, COMO POLIOLES, POLIACIDOS, RESINAS ALCALINAS, RESINAS DE POLIESTER, EPOXIS, ACRILICOS Y SIMILARES. LOS REVESTIMIENTOS QUE CONTIENEN RESINA AMINO, CO-REACTIVO, Y CATALIZADOR LATENTE TIENEN UNA ESTABILIDAD DE VISCOSIDAD ACEPTABLE, SOLIDIFICAN RAPIDAMENTE A TEMPERATURAS MAS BAJAS QUE OTROS CATALIZADORES LATENTES Y PRODUCEN PELICULAS SIN ARRUGAS.
