<p>The invention relates to a binder composition, a powder paint composition and a cross-linker that result in mat powder coatings. The mat powder coatings are obtained by adding melamine particles having a relatively small particle size. In a preferred embodiment a powder paint composition comprises (i) a polymer capable of reacting with epoxy groups, (ii) a cross-linker containing epoxy groups, wherein the cross-linker comprises at least one C5-C26 linear or branched aliphatic chain and the cross-linker has an epoxy functionality greater than 1, with the proviso that the epoxy groups are carried on the at least one aliphatic chain and (iii) melamine.</p> |
