The emulsion was prepared using commercially available surfactants and free of volatile organic substances (VOCs). The most applicable technology for the production of alkyd-siloxane emulsions is direct emulsification at a temperature of 60°C, and using dynamic light scattering, the hydrodynamic radius of the particles was determined to be 132 ± 38 nm. The resulting emulsion has an aggregative and sedimentation stability during storage up to 3 months; however, the temperature difference causes the destruction of the colloidal system. The curing reaction occurs within 10 min to form a coating containing 95% gel fraction. Emulsion-based coatings have better properties relative to alkyd coatings but are not significantly inferior to coatings from an organo-soluble UV-curable composition. Coatings based on UV-cured materials have shown low chemical resistance, which limits their use in conditions where contact with aggressive liquids occurs. The presence of surfactants in the coating reduces the water contact angle by 4° and increases water absorption by 1.5% relative to coatings based on organo-soluble alkyd-siloxane composition. Sorption studies have shown that the diffusion coefficients of water into the coating from the emulsion and the organo-soluble system have the same values and amount to 8.35·10⁻⁹ cm²/s. The difference in the glass transition temperature of coatings obtained from an emulsion (21.0°C) and a solution (24.2°C), as well as a decrease in heat resistance, indicates a lower degree of crosslinking due to the presence of surfactants in the system. Elemental and morphological analysis showed that there is no phase decay during the process of coating formation, and all elements are evenly distributed over the surface. A comparative analysis of the results of the study with the literature data showed that the obtained emulsion is not inferior in properties to other UV-curable water-based materials.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 3","pages":"1185 - 1205"},"PeriodicalIF":2.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Characterizing these microstructural changes is challenging given the transient nature of drying and the presence of water within samples. The present work proposes a freeze-drying preparation method that captures intermediate microstructural states during latex film formation so that they can be characterized by scanning electron microscopy (SEM) at room temperature. To develop this method, aqueous coatings prepared from diluted styrene acrylic latex (Primal DC-420, DOW Chemical) were deposited onto silicon substrates and dried just above the latex minimum film formation temperature (MFFT) of ~ 30°C. Coatings were then flash-frozen at various time points during drying, and then the ice within the frozen coating was sublimed under vacuum (<i>P</i> &lt; 200 Pa). Specimens were stored and sputter coated with platinum at low temperature (&lt;0°C) before SEM imaging. Surface and cross-sectional images showed multiple stages of film formation, enabled by a lateral drying front. Parallel cryogenic SEM studies verified that the freeze-drying method comparably captures microstructure after latex particles consolidate into a network. Studies with lower MFFT coatings, including those made from a different latex (Acronal S 790, BASF) or from Primal DC-420 with a coalescent (Texanol, Eastman Chemical), demonstrated the importance of storing and sputter coating specimens at temperatures less than the MFFT to maintain the microstructures for room temperature SEM imaging. Through the freeze-drying method, microstructures associated with all three stages of film formation (consolidation, compaction, and coalescence) were visualized, enabling the continued development and improvement of latex-containing coating formulations.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 3","pages":"1171 - 1184"},"PeriodicalIF":2.3,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-024-01044-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
