Basic copper carbonate
Description
Basic copper carbonate (CAS 12069-69-1), also known as copper carbonate hydroxide, is an inorganic copper salt supplied as a fine green powder. It functions as a source of bioavailable copper and as a biocidal active across multiple industrial sectors.
In agriculture, it serves as a fungicide and seed treatment agent, protecting cereal and vegetable crops against soil-borne pathogens before germination. Animal feed manufacturers incorporate it as a copper mineral supplement to meet livestock nutritional requirements.
In antifouling and wood preservation coatings, it acts as the primary biocidal component, inhibiting microbial and algal growth on marine and structural surfaces. Building and construction formulators use it in pigment applications.
It is also utilized as a corrosion-inhibiting additive in protective coatings. Basic copper carbonate is supplied as a fine green powder in technical and feed-grade specifications to meet various industrial needs.
Feed-grade material is produced to meet purity standards suitable for animal nutrition applications, while technical grade serves industrial coating and preservation uses. Quality is maintained through rigorous production controls.
Bulk packaging in bags and bulk containers is standard, with copper content typically specified as a key quality parameter. This ensures consistency for large-scale manufacturing and agricultural distribution across global markets.
