Application and Recommended Dosage: Used as biocide (controls slime forming bacteria and fungi) in aqueous functional fluids (metalworking, cutting, cooling, and lubricating), latex emulsions (adhesives, caulks, patching compounds, sealants, pastes, and grouts), aqueous fiber lubricants and inks, jet-printer inks, laundry rinse additives and detergents, carpet cleaners, analytical and diagnostic reagents; Also used as in-can preservative for water based mixtures used in making concrete.
Application sites: In metalworking fluids, paints, inks, adhesives, plastics, laundry rinse additives, polymers, and floor finishes.
– Types and methods of application: For manufactured materials (i.e. plastics, paints, adhesives, etc.), to add at any point during the manufacturing process. As a preservative (i.e. in metalworking fluids and inks), add directly to the solution to be preserved.
Application /Dosage rates: For metalworking fluids, use 0.02 -0.06% of fluid; for inks, use 0.11 – 1.7% of of ink; for paints, use 0.22- 0.56% of of paint; for plastics and polymers, use 0.22 – 0.45% of plastic or polymer.
Handling of Kopthione Na: Where direct handling is necessitated, personnel should always wear protective clothing. This will include a rubber apron, suitable impervious full-length gloves and footwear. Protective chemical splash goggles should also be worn.
Addition and compatibility: Sodium Pyrithione is stable under normal environmental conditions if stored in closed, dark containers. At 100° C it is stable for 24 hours. In the light or in contact with weak oxidizing agents sodium pyrithione is converted to the disulfide, 2, 2-pyridyl-N-oxide disulfide. With stronger oxidizing agents or in alkaline solution (pH > 9.5) the substance is converted via a number of intermediates to the sulfonic acid.
Even alkalinity of metal working fluids is not affected by the addition of Sodium pyrithione. Compatible with most raw materials used in technical applications.
Spillage/Disposal: Spillages should be absorbed using an inert material such as vermiculite and
transferred to containers for disposal. Spillages should be disposed according to local regulations.
