Solvent-borne, Speciality Additive, Wetting & Levelling Agent

VP 7380 Non-Silicone Fluorine-Free Levelling agent

7380 is a high-performance, non-silicone, and fluorine-free levelling agent specifically engineered for advanced coating systems requiring superior surface aesthetics without the traditional risks associated with silicone contamination. Developed as a sustainable alternative to fluorinated additives, this specialized polyacrylate-based polymer facilitates exceptional substrate wetting and promotes a flawlessly smooth film surface. Its primary mechanism involves the strategic reduction of surface tension differentials, effectively eliminating common film defects such as orange peel, craters, and pinholes. Unlike conventional silicone additives, 7380 does not impair intercoat adhesion or cause recoatability issues, making it an ideal selection for multi-layer automotive coatings, industrial finishes, and high-gloss wood stains. By maintaining a stable surface energy profile, it ensures consistent application across diverse substrates, including low-energy plastics and metals. As global regulations increasingly restrict the use of per- and polyfluoroalkyl substances (PFAS), 7380 offers a compliant, eco-friendly solution for manufacturers prioritizing environmental safety without compromising mechanical performance standards.
