The coating was obtained through a thiol-ene click addition reaction using methyl oleate and 3-mercaptopropyltrimethoxysilane in the presence of the photoinitiator 2,2-dimethoxy-2-phenylacetophenone (DMPA). This reaction proved to be more efficient compared with other tested (photo)initiators, considering the double bond conversion of oleate. The coating was applied to concrete using two methods: immersion and brushing. Both methods exhibited similar consumption of methyl oleate-based silane (UVMeS) at approximately 20 g\/m2. The hydrophobic properties of the coatings were evaluated based on the contact angle, which for the modified surfaces was above 93\u00b0, indicating their hydrophobic nature. The penetration depth of the silane solution into the concrete was also studied; it was 5\u20137 mm for the immersion method and 3\u20135 mm for the brushing method. The addition of tetraethoxysilane (TEOS) to the silane solution slightly improved the barrier properties of the coating.<\/jats:p>","DOI":"10.3390\/ma17174432","type":"journal-article","created":{"date-parts":[[2024,9,9]],"date-time":"2024-09-09T09:21:00Z","timestamp":1725873660000},"page":"4432","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Protective Coatings Based on the Organosilicon Derivatives of Fatty Acids Obtained by the Thiol-Ene Click Reaction"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0029-8671","authenticated-orcid":false,"given":"Karol","family":"Szubert","sequence":"first","affiliation":[{"name":"Faculty of Chemistry, Adam Mickiewicz University, Uniwersytetu Pozna\u0144skiego 8, 61-614 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0210-5979","authenticated-orcid":false,"given":"Albert","family":"Liberski","sequence":"additional","affiliation":[{"name":"Construction Research and Innovation Laboratory, Innova Seminars, Doha 24144, Qatar"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,9]]},"reference":[{"key":"ref_1","unstructured":"Khan, M.
