Overview
Copper formate is a copper salt of formic acid, appearing as blue crystals. It is primarily used as an antibacterial and antifungal agent in the treatment of cellulose-based materials, such as textiles, paper, and wood products. Its copper content provides effective biocidal activity, helping to prevent microbial growth and decay.

Applications

• Cellulose treatment: Used as an antibacterial agent for fabrics, paper, and other cellulosic materials to impart antimicrobial properties.

• Wood preservation: Applied as a fungicidal treatment to protect wood from decay and insect attack.

• Catalysis: Can serve as a catalyst or precursor in certain organic reactions.

• Chemical intermediate: Used in the synthesis of other copper compounds and specialty chemicals.

Handling and Storage

• Store in a cool, dry, well-ventilated area, away from oxidizers and strong bases.

• Keep containers tightly sealed to prevent moisture absorption and contamination.

• Avoid contact with incompatible materials (strong acids, oxidizing agents).

• Use appropriate personal protective equipment (gloves, safety goggles, dust mask) when handling.

Safety

• Harmful if swallowed; may cause skin and eye irritation.

• In case of skin contact, wash with soap and water; for eye contact, rinse thoroughly with water.

• Refer to the Safety Data Sheet (SDS) for detailed safety information.
