Zusammenfassung:	A method for production of polyurethane coatings with low surface energy modified with a block copolymer polydimethylsiloxane–polyphenylsilsesquioxane is presented. Surface characteristics of coatings were studied by methods of measuring the contact angle, attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy and scanning electron microscopy with X-ray spectral microanalysis, and the values of static contact angles and surface energy were obtained. The effect of pigmentation on wetting and physicomechanical characteristics of low-energy coatings has been investigated.
