Zinc naphthenate is widely used as a drier in oil-based paints, varnishes, and printing inks. It accelerates the curing process by promoting the oxidation and polymerization of drying oils, leading to faster film formation and improved surface hardness. Its solubility in organic solvents makes it ideal for integration into hydrophobic coatings systems. It also serves as a wood preservative due to its fungicidal and mildew-resistant properties. When applied in protective coatings for wood, it helps prevent degradation caused by moisture and microbial growth. Additionally, zinc naphthenate is used in some industrial lubricants and greases to enhance anti-wear and corrosion-inhibiting performance. Because of its thermal stability, it finds use in fuel and oil additives, where it helps neutralize acidic byproducts and reduce metal surface corrosion. Its compatibility with other metal naphthenates allows it to be part of synergistic blends in multi-metal drier systems for high-performance coatings.
