Chemical Properties
Amber, viscous, basic liquid or basic
solid. The liquid contains 8–10% zinc, the solid
contains 16% zinc. Very soluble in acetone. Combustible.
Characteristics
Zinc naphthenate is an important organozinc compound, commonly used as a catalyst, stabilizer, and coordinating agent.
Corrosion Inhibition: Zinc ions form coordination bonds with naphthenate carboxylate anions, creating a dense, protective film on metal surfaces that effectively isolates them from oxygen, moisture, and corrosive media.
Lubricity: During cutting operations, it forms a lubricating film that reduces friction and wear, thereby enhancing processing efficiency.
Antimicrobial Activity: It inhibits the growth of bacteria and fungi, preventing the spoilage of media, such as cutting fluids, caused by microbial contamination.
Catalytic Activity: It participates in organic synthesis reactions as a catalyst, accelerating reaction rates and improving product selectivity.
Uses
Drier and wetting agent in paints, varnishes,
resins; insecticide; fungicide; mildew preventive;
wood preservative; waterproofing textiles; insulating
materials.
