Abstract
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.
