Abstract: The invention relates to a method for applying a RMA crosslinked coating with improved adhesion, comprising the steps of applying on the substrate surface a layer of a modified epoxy primer comprising an epoxy functional polymer binder and a crosslinker, wherein adhesion of the RMA crosslinked coating to the epoxy primer layer is improved by said primer comprising after curing functional groups X reactable with crosslinkable components of the RMA crosslinkable composition or a precursor of functional groups X, preferably a moisture deblockable precursor. The invention also relates to modified epoxy primers, compositions for improving adhesion of epoxy primers and use thereof to improve adhesion of RMA crosslinkable coatings.
