Cuprous oxide

Cuprous oxide (CAS 1317-39-1), also known as copper(I) oxide, is an inorganic compound used industrially as a biocidal pigment and surface-active agent.

Where is Cuprous oxide used?

• Marine and antifouling coatings: primary biocidal pigment preventing barnacle and algae attachment on submerged surfaces
• Agricultural formulations: copper-based fungicide and bactericide for crop protection, particularly in seed treatments and foliar sprays
• Textile and leather processing: imparts antimicrobial properties to finished fabrics and hides
• Electronics: conductive pigment
• It delivers both color and antimicrobial performance in a single raw material.

Commercial specifications

• Fine red-to-brown powder in varying particle size distributions suited to coating or agricultural end uses
• Technical grade: purity typically 97% to 99%
• Specialized grades with controlled particle size
