Hydroxyl fluorosilicone oil is a special organosilicon material that combines active hydroxyl groups with fluorocarbon segments. The strong electronegativity of fluorine atoms in its molecular structure, combined with the flexibility of the Si-O backbone, creates a synergistic advantage, resulting in distinctive properties and unique functions. It has extremely low surface energy, exhibiting excellent oleophobic and hydrophobic properties, weather resistance, and chemical corrosion resistance. It can resist the erosion of strong acids, alkalis, and organic solvents, and maintains stable performance even after long-term exposure to high temperatures and ultraviolet radiation. The hydroxyl groups endow it with reactivity, allowing it to cross-link and cure with isocyanates, epoxy resins, and other components to form a dense film layer, balancing adhesion and wear resistance. It also boasts excellent compatibility, allowing for compounding with various resins and additives.
Applications are concentrated in high-end protection and functional modification fields. In the coatings industry, it is used to prepare fluorosilicone-modified coatings, suitable for protecting building exteriors and metal components, improving stain resistance and corrosion resistance. It can also be used as a wear-resistant additive in wood coatings. In the electronics field, it is used for surface protection of semiconductors and circuit boards, forming a moisture-proof and insulating film layer. In the textile industry, it can be used to produce high-grade fabric finishing agents, giving fabrics water- and oil-repellent, stain-resistant properties and a soft hand feel. In addition, in the mold and optical device fields, it can be used as a release agent and anti-fouling coating, meeting the needs of precision machining. With its differentiated properties, its demand in the high-end new materials market is steadily growing.
