A surface coating agent can be oxidized, for tackifiers or binders are used in peptide

The present invention relates to a peptide comprising, in particular coating agent dodecapeptide tackifier or adhesive, for oxidation of the surface, or a composite multilayer coated substrate, comprising wholly or in part by dodecapeptide compound formed, the adhesion promoter compound between at least two adjacent layers or between a coating layer and the composite matrix further relates to a coating agent may be used as surface oxidation tackifier or adhesion twelve peptide mixture.
