摘要： The present disclosure provides a hydrophobic and oleophobic coating composition, which comprises the following components based on weight percentage: 0.1-15% of a fluorosiloxane, 1-30% of a polyacrylic resin, 0.1-15% of a silane coupler, 33-98% of an organic solvent, and 0.05-15% of an acid. By combining the polyacrylic resin and the fluorosiloxane which exhibits hydrophobic property, the present composition not only provides good hydrophobic property but also ensures durable hydrophobic property of the coating with the help of good adhesion of polyacrylic resin. The coating composition can form hard coating which has high glossiness and high transparency under relatively low temperatures and has a contact angle of 115-120. This coating composition can be used on surfaces of substrates, such as automotive paints, metal, plastic and glass, and it can retain long lasting hydrophobic and oleophobic property even placed outdoors for several months, and it can also prevent the surface of the substrate from being scratched.
摘要翻译：本公开内容提供疏水和疏油涂料组合物，其包含基于重量百分比的以下组分：0.1-15％的氟硅氧烷，1-30％的聚丙烯酸树脂，0.1-15％的硅烷偶联剂，33-98 ％的有机溶剂和0.05-15％的酸。通过组合聚丙烯酸树脂和显示疏水性的氟硅氧烷，本发明的组合物不仅提供了良好的疏水性，而且借助于聚丙烯酸树脂的良好粘附性，确保了涂层的耐久的疏水性。涂料组合物可以形成硬涂层，其在相对低的温度下具有高光泽度和高透明度，并且具有115-120的接触角。该涂料组合物可以用于汽车涂料，金属，塑料和玻璃等基材的表面，并且可以保持长时间的疏水性和疏油性，甚至可以在室外放置数月，并且还可以防止基材的表面被划伤
