An investment agreement was signed between Science-based Holding of Future Nano Tech Industries (Santa) and Science-based Maral Nano Coating Company for the production of super-hydrophobic coatings.
In order to support knowledge-based industries and also to respond to the demand for new super-hydrophobic coatings in the country, the Science-based Holding of Future Nanotech Industries (Santa) concluded an investment contract with the science-based company Maral Nano Coating.
In nature, there are various surfaces, such as butterfly wings and cabbage leaves, which show super-hydrophobic properties. One of the best examples of these is the surfaces of lotus leaves. In recent years, inspired by nature, new methods have been developed to produce super-hydrophobic coatings. One of the most high-quality types of super-water-repellent coatings is polyurethane coatings. Polyurethane (PU) is the general name of polymers that have urethane bonds (NHCOO). The urethane bond is formed through an addition reaction between an isocyanate group and a compound with an active hydrogen such as a hydroxyl group. Isocyanate groups are highly reactive, and for this reason their reaction progress does not require an increase in temperature (the reaction takes place at ambient temperature). Compounds that have more than two hydroxyl (OH) groups are called polyols, and polyetherpolyol, polyesterpolyol and polycarbonate polyol species are usually used in polyurethane synthesis. Compounds that have an isocyanate group include toluene diisocyanate (TDI), diphenylmethane diisocyanate (MDI) and hexamethylene diisocyanate (HDI). Two-component polyurethane coatings are used for covering trains, bridges and trucks due to their good chemical and abrasion resistance. Aliphatic isocyanates such as HDI are used in sun-exposed coatings because they are resistant to UV rays.
