The present invention relates to a coating composition which contains a one- or two-component binder and, in addition, an adhesion promoter which is based on a chemically modified, amorphous polyolefin having an average molecular weight M.sub.w (weight average) in the range from 10,000 to 100,000 g/mol, a non-uniformity U.sub.n of 1.0 to 6.5, a chlorine content of about 2.5 to 50% by weight and a total content of nitrogen, oxygen, sulfur and silicon, in the form of chemically incorporated functional groups, of about 2.5 to 15.0% by weight. The present invention also relates to a process for coating plastic substrates with this coating composition and to the coated plastic substrates obtained in accordance with this process.

Coating compositions containing chemically modified amorphous

An improved process for depositing strongly adhering metallic coatings on substrate surfaces by wet chemical methods by treating the surfaces with a primer before activation. The materials produced by the process are eminently suitable for the shielding of electromagnetic waves.

Process for metallizing substrate surfaces

The present invention relates to the use of polysiloxanes containing amino groups as additives for improving levelling and wetting of polyurethane-based coating compositions applied to plastic substrates. The present invention additionally relates to the coated plastic substrates.
