Study on the Application of Hydrophilic and Easy - Cleaning Coating

Abstract

In order to provide a basis for the application of hydrophilic coating in high temperature and high humidity environment, the hydrophilic and easy - cleaning coatings applied on stainless steel substrates were studied and the influences of the substrate and coating changes on the hydrophilicity and high - temperature and steam resistances were analysed. Results showed that the water contact angle of SUS304 stainless steel was obviously lower than that of SUS430 stainless steel when these two steels were covered with commercialized alkaline silicate hydrophilic coating ZC and self - made lithium silicate hydrophilic coating JY. And the hydrophilic and easy - cleaning properties of the commercialized coating ZC was better than that of the self - made coating JY. The temperature resistance and steam resistance test results showed that the lithium silicate coating had better stability and water resistance, which was suitable for steam oven application.
