Performance Test and Application of Copper pyrithione
Copper pyrithione is a broad-spectrum, efficient, low toxic, environmentally friendly bacteriostat and antifouling agent. It is a grass - green, crystalline powder - not dissolve in water.
It shows that copper pyrithione has high stability, it can be stored for a long time and the quality is kept constant Under the condition of avoiding light. Since copper pyrithione is a bacteriostat and antifouling agent, it can be used in architectural coatings, metal processing, marine antifouling lacquers, pesticides and so on.
It has been proves that copper pyrithione not only has acute oral LD50>1000mg/kg, but also has no irritation to skin. This will further promote the wide application of copper pyrithione in various fields.
Although copper pyrithione is low toxic and safe to use. But it still needs to avoid contact with mouth, eyes and skin.
In actual use, copper pyrithione can be directly added to the coating, the coating showed the stability of gel coating, so as to prolong the storage time; or for marine antifouling paint, can prevent crustaceans, algae and aquatic organisms attached to hull plate effectively.
