What is Oamiguard BL10 Preservative?

Oamiguard BL10 is a broad-spectrum preservative containing a certain dosage of 1,2-benzisothiazolin-3-one (BIT), with water as the solvent. It is used to protect water-based industrial products from bacteria, yeasts and molds, and is widely applied in water-based industrial product systems such as synthetic polymer emulsions, latex paints, water-based adhesives, printing inks and metalworking fluids.
