Abstract

La presente invención proporciona polvos de revestimiento que permiten la resistencia mejorada a la corrosión filiforme en revestimiento transparente con color o transparente que comprende un componente de copolímero acrílico funcional con epoxia que tiene una Tg de desde 40ºC a 90ºC y seleccionado de un copolímero o mezcla de copolímeros que comprende, en base al resto total de monómeros copolimerizados en el componente de copolímero acrílico funcional con epoxia, i) de 10 a 40% en peso de uno o más monómeros insaturados funcionales con epoxia, e.g., (met)acrilato de glicidilo; ii) de 2.0% en peso a 13% en peso, preferentemente 12% en peso o menos, o, más preferentemente, 6% en peso o menos, de uno o más monómeros acrílicos hidrofóbicos que tienen una solubilidad de masa en agua de 3.5 g/l o menos y que por sí mismo formaría un homopolímero que tiene una temperatura de transición vítrea (Tg) de 50ºC a 175ºC; e.g., un (met)acrilato de bicicloalquilo, y iii) el resto de uno o más comonómeros no iónicos que no es un monómero acrílico hidrofóbico (ii), e.g. metacrilato de metilo; uno o más reticuladores para el copolímero acrílico termoestable; y, opcionalmente, uno o más promotores de adhesión, e.g., resina de epoxia, un estabilizador de luz, un absorbente de luz ultravioleta (UV), y/o una partícula hidrofóbica submicrónica.
