Superhydrophobic coatings are currently not widely used due to complex scaling problems, high cost and low environmental resistance. One solution is the use of organic coating technology. The paper shows the possibility of obtaining surface coatings with high water-repellent properties based on expanded perlite and regenerated adsorbent. The most effective surface treatment is polymethylhydrogensiloxane. In the work properties of obtained coatings were characterized by contact angles using the sessile droplet technique, optical and electron microscopy and IR-spectroscopy. With polymer content is more than 50 wt% for untreated and more than 40 wt% for the polymethylhydrogensiloxane treated perlite, the Cassie steady state and the water contact angle of more than 140° were reached. The resulting coatings are an example of a good microscale base coat for the further creation of superhydrophobic volumetric hierarchical coatings. It has been shown that the use of an adsorbent for used refined sunflower oil is as effective as the use of freshly ground expanded perlite.
