Copper naphthenate CAS 1338-02-9 CuN

Copper cyclopentaneate (CuN for short), also known as copper naphthenate and copper petroleum acid, has the molecular formula (C10H19COO)2Cu. It is a complex of alkylphenol polyoxyethylene ethers. It is soluble in water of any hardness, acid and alkali resistant, and has excellent properties such as emulsification, leveling, wetting and diffusion. It can be mixed with various types of surfactants and dye resin pre-condensation bodies. Copper cyclopentaneate is prepared by dissolving copper oxide or copper carbonate with cyclopentane acid, or by double decomposition reaction of soluble copper salt and sodium cyclopentaneate. The copper content of commercial copper cyclopentaneate is 6% to 8%. It is a dark green viscous substance that is insoluble in water and soluble in petroleum solvents. It has a special musty smell, is very low in toxicity to humans and animals, and has relatively stable chemical properties. It is a highly efficient, low-toxic, environmentally friendly wood preservative. In recent years, it has been paid special attention to. It is mainly used for the anticorrosion of woodworking, gardening and shipbuilding materials. It has a strong ability to prevent the invasion of marine drilling animals. As an exudation aid in antifouling paint, it can be used in ship antifouling paint to toughen the paint film and increase the exudation rate of the antifouling agent. It can achieve the purpose of regulating and controlling the exudation of the antifouling agent. Recommended dosage: 0.05-0.2% (metal to resin solids). It can also be used as an anticorrosion and mildew-proof agent for cables, cloth and leather. Recently, water-borne copper naphthenate has been developed, using organic amines as solvents, which has created conditions for the promotion and application of copper naphthenate.
