Used as a pigment in paints and coatings due to its stable color and resistance to weathering. Also applied in agricultural formulations as a fungicide for crop protection, especially in vineyards and orchards. Its low solubility allows for slow release of copper ions, providing long-lasting antimicrobial activity. Additionally, it is incorporated into anti-fouling paints for marine structures to prevent the growth of algae and barnacles. Shows use in corrosion-resistant primers for metals in industrial settings.
