Copper Naphthenate

Chemical structure of Copper Naphthenate

Copper Naphthenate is a chemical compound that is widely used as a wood preservative. It is a mixture of copper salts of naphthenic acids, which are derived from petroleum. Copper Naphthenate is known for its effectiveness in protecting wood against decay, fungi, and insect damage. It is commonly used in the construction industry for treating outdoor wood structures such as fences, decks, and utility poles.

History

Copper Naphthenate was first developed in the early 20th century as a wood preservative. Its use became widespread due to its effectiveness and relatively low toxicity compared to other wood preservatives available at the time. Over the years, it has been extensively studied and refined to improve its performance and safety.

Properties

Copper Naphthenate is a dark green liquid with a characteristic odor. It is soluble in organic solvents and has a low water solubility. The active ingredient in Copper Naphthenate is copper, which acts as a fungicide and insecticide. The naphthenic acids provide stability and enhance the penetration of the copper into the wood.

Application

Copper Naphthenate is typically applied to wood surfaces by brushing, spraying, or dipping. It can be used on both untreated and previously treated wood. The preservative is absorbed into the wood, providing long-lasting protection against decay and insect infestation. It is important to follow the manufacturer's instructions and safety guidelines when using Copper Naphthenate.

Environmental and Health Considerations

Copper Naphthenate is considered relatively safe for humans and the environment when used as directed. However, it is important to take precautions when handling and applying the preservative. Protective clothing, gloves, and goggles should be worn to minimize skin contact and inhalation of fumes. It is also recommended to apply Copper Naphthenate in well-ventilated areas.
