Copper Pyrithione Market Analysis by Global Segments, Growth | 2026
Pyrithione is an organic chemical that is used in various forms as an industrial biocide. Pyrithione is also known as 2-pyridinethiol-1-oxide, 1-Hydroxy-2-pyridinethione, 2-mercaptopyridine-N-oxide, pyridinethione-N-oxide, pyridine-2-thione-N-oxide, 2-pyridinethione, pyridinethione, or PT. It is known for its fungicidal and bactericidal properties. It has been predominantly employed as an antifouling agent in marine ships for several decades. Several metal compounds of pyrithione are used as a biocide, of which two are most commonly used: zinc pyrithione and copper pyrithione. Copper pyrithione is relatively more toxic and hence, it is largely used in industrial applications. One of the key uses of copper pyrithione is its application as a biocide in marine paints to prevent accumulation of marine flora and fauna on ship hulls. Copper pyrithione is also employed in anti-fouling paints. Mostly, it is used as a co-biocide (or booster biocide) along with another biocide suc...
