The relation between the contact angle of the cured coating and the type of the organosilicon polymer is analyzed. It has been found that the water-repellent properties of the coatings are influenced by the composition of these polymers. Using spectroscopic studies, the mechanism of hydrophobisation of coatings was explained. The analysis of spectral maps along the cross section of the coatings has shown polysiloxane additives migration from the substrate into the coating/air interface. The arrangement of polysiloxanes in cross-section of the coatings was varied and depended on the weight fraction of organic resin in the paint formulation and the chemical composition of polysiloxanes. Tests were carried out using an IR Continuum microscope. The analysis was conducted on cured coatings derived from acrylic paints containing polysiloxanes based on:  polydimethyl siloxane PDMS, polymethylvinyl siloxane PMVS and polymethylphenyl siloxane PMPS. The highest mobility was shown by PDMS and PMVS based polysiloxanes. The width of the segregation area for PMPS was greater, which confirms low migration tendency of this polysiloxane.
