description La invención se refiere a un método para aplicar un recubrimiento RMA reticulado con adherencia mejorada, que comprende los pasos de aplicar sobre la superficie del sustrato una capa de una imprimación epoxi modificada que comprende un aglutinante de polímero funcional epoxi y un reticulador, en donde la adhesión del recubrimiento RMA reticulado a la capa de imprimación epoxi se mejora mediante dicha imprimación que comprende después del curado grupos funcionales X reaccionables con componentes reticulables de la composición reticulable RMA o un precursor de grupos funcionales X, preferiblemente un precursor desbloqueable por humedad. La invención también se refiere a imprimaciones epoxi modificadas, composiciones para mejorar la adhesión de imprimaciones epoxi y el uso de las mismas para mejorar la adhesión de revestimientos RMA reticulables. (Traducción automática con Google Translate, sin valor legal) The invention relates to an adhesion promotor for improving adhesion on a substrate surface of an RMA crosslink able composition comprising one or more crosslinkable components comprising a reactive component A with at least two acidic protons C-H in activated methylene or methine groups, a reactive component B with at least two activated unsaturated C═C groups, a catalyst C for catalyzing the RMA crosslinking reaction between components A and B, said adhesion promotor P comprising a moiety comprising one or more functional groups X or precursors thereof readable with component A or component B and a moiety comprising one or more functional groups Y or precursors thereof that adsorb or react with the substrate surface not being an alkoxysilane group. The invention also relates to a RMA crosslinkable composition, also in the form of a kit of parts, to a premix for use as a part in the kit of parts.
