Q1: What is the primary active ingredient in Nipacide BIT AS 20?
A: The active ingredient is 1,2-benzisothiazol-3(2H)-one (BIT), supplied as a stable aqueous suspension at 20% active concentration. It functions as a broad-spectrum biocide effective against bacteria, yeasts, and molds.
Q2: In which types of industrial formulations is Nipacide BIT AS 20 commonly used?
A: It is widely applied in water-based industrial products such as metalworking fluids, latex paints and coatings, adhesives, construction chemicals, and cleaning concentrates—where long-term microbial stability is required during storage and use.
Q3: Is Nipacide BIT AS 20 compatible with common formulation components?
A: Yes, it demonstrates good compatibility with anionic, nonionic, and amphoteric surfactants, many thickeners, and typical pH adjusters. Stability is generally maintained across a pH range of approximately 4–10, though performance may vary depending on specific system composition and ionic strength.
Q4: How should Nipacide BIT AS 20 be dosed in a formulation?
A: Dosage depends on formulation requirements, challenge level, and regulatory considerations in the target market. It is typically used at low concentrations, generally ranging from 0.1% to 2% by weight of the final product, with optimal levels determined through preservative efficacy testing (PET) under relevant conditions.
