Copper naphthenate with the CAS number 1338 - 02 - 9 is a high - quality product. It is a coordination compound of copper and naphthenic acid. Physically, it usually appears as a dark green to black viscous liquid. Its density can vary depending on the specific formulation, but generally, it is in the range of around 1.0 - 1.2 g/cm³. The boiling point is relatively high, often above 200°C, and it has a characteristic odor associated with naphthenic compounds.
The chemical structure of copper naphthenate consists of copper ions coordinated to the carboxylate groups of naphthenic acids. This coordination gives the compound certain chemical and physical properties that make it useful in various applications. The product we offer is of high purity, ensuring its effectiveness and reliability in different uses.
Copper naphthenate has a wide range of applications. One of the primary uses is as a wood preservative. It can penetrate the wood fibers and protect the wood from decay, fungi, and insects. By forming a protective layer within the wood, it significantly extends the lifespan of wooden structures such as fences, decks, and utility poles.
In the paint and coating industry, copper naphthenate can be used as a drier. It accelerates the drying process of oil - based paints and coatings, improving their hardening and adhesion properties. This leads to a more durable and better - looking finish on various surfaces, including metals, plastics, and wood.
It is also used in the rubber industry as an antioxidant. It helps to prevent the oxidation and degradation of rubber materials, enhancing their mechanical properties and resistance to aging. This makes it suitable for use in rubber products such as tires, seals, and hoses.
When using copper naphthenate as a wood preservative, the wood should be clean and dry. The product can be applied by brushing, spraying, or dipping. For brushing, use a high - quality paintbrush to evenly coat the surface of the wood. Make sure to cover all areas, especially the ends and joints. When spraying, use a suitable sprayer and maintain an appropriate distance from the wood surface to ensure a uniform application. Dipping is a more effective method for complete penetration, but it requires a large container to hold the wood and the preservative solution.
In the paint and coating industry, copper naphthenate should be added to the paint or coating formulation at the recommended dosage. Stir the mixture thoroughly to ensure even distribution. The addition should be done during the mixing stage of the paint production process.
For use in the rubber industry, it is usually incorporated into the rubber compound during the mixing process. The amount added depends on the specific requirements of the rubber product, such as the desired level of antioxidant protection and the type of rubber being used.
Case 1: A wooden fence in a coastal area was treated with our copper naphthenate as a preservative. Before treatment, the fence was showing signs of fungal growth and insect damage. After applying the copper naphthenate by brushing, the fence was protected from further decay. Over a period of five years, the fence remained in good condition, with no visible signs of fungal or insect infestation. The color of the wood also remained relatively stable, and the structure maintained its integrity.
Case 2: An oil - based paint manufacturer added copper naphthenate to their paint formulation as a drier. The paint was used to coat metal furniture. The addition of copper naphthenate reduced the drying time of the paint from 24 hours to 12 hours. The final finish had a better gloss and was more resistant to scratches and abrasion. Customers were highly satisfied with the improved quality of the painted furniture.
Case 3: A rubber hose manufacturer incorporated copper naphthenate into their rubber compound as an antioxidant. The hoses were used in automotive applications. After extensive testing, it was found that the hoses treated with copper naphthenate had a significantly longer service life. They showed less cracking and degradation even under high - temperature and high - pressure conditions.
