Advantages.：Sodium Pyrithione is a non-VOC, broad spectrum, highly effective antimicrobial agent. It is used to control mold, mildew, fungi, yeasts, algae, and both gram (+) and gram (-) bacteria. Sodium Pyrithione also has excellent heat and pH stability.
Safety.：Concentrated Sodium Pyrithione may be harmful if ingested, inhaled, or in contact with the skin as absorption can occur; however, diluted at recommended use levels, it is considered non-toxi
