Abstract:
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.
