The exterior walls of high-rise buildings accumulate dust and become black over time, and the cleaning cost is extremely high. Methyl fluoride-modified silicone oil, with its extremely low surface energy, endows the coating with a waxy hydrophobic self-cleaning function. It is the core modified raw material for high-end exterior fluorocarbon paints. Ordinary exterior coatings allow water droplets to spread and adhere, while mud and sand firmly adhere. After adding fluorosilicone oil, the contact angle of the coating with water can reach over 120°. Rainwater falling on the wall automatically condenses into water droplets and rolls off, simultaneously removing 90% of the surface dust, significantly reducing the frequency of building cleaning.
This silicone oil is resistant to acids and alkalis and UV rays. Its hydrophobic property does not deteriorate even after ten years of exposure to the sun. At the same time, it enhances the wear resistance and scratch resistance of the paint film. Even slight friction from sand and branches will not leave permanent scratches. It is suitable for long-term outdoor scenarios such as office building exteriors, bridge anti-corrosion, and real stone coating of villas. Water-based fluorosilicone oil has no solvent evaporation and complies with the standards for green building coatings.
After introducing IOTA fluorine-modified silicone oil into the coating formula of a certain super high-rise building, the exterior walls do not require manual cleaning for five years, and the comprehensive operation and maintenance cost is reduced by 60%. With the urban renewal and expansion of high-end real estate projects, the market for self-cleaning silicon-modified exterior coatings has expanded rapidly, and fluorine-based special silicone oil has become a high-value-added sector for coating additives.
