Q1: What is Solvay Bricorr 70A Biocide primarily used for?
A: Solvay Bricorr 70A Biocide is a broad-spectrum preservative designed to inhibit microbial growth—particularly bacteria, yeasts, and molds—in water-based industrial formulations, including coatings, adhesives, construction chemicals, and cleaning products.
Q2: Is Bricorr 70A compatible with common formulation ingredients such as surfactants, thickeners, and pigments?
A: Yes, Bricorr 70A demonstrates good compatibility with a wide range of formulation components, including nonionic and anionic surfactants, associative and cellulosic thickeners, and inorganic pigments. Compatibility testing under actual formulation conditions is still recommended to confirm stability and efficacy.
Q3: How should Bricorr 70A be incorporated into a formulation?
A: It is typically added during the final stage of manufacturing, after pH adjustment and cooling, to avoid degradation from high temperatures or extreme pH. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight, based on total batch mass.
Q4: Does Bricorr 70A remain effective over the product’s shelf life?
A: When properly dosed and stored under recommended conditions (cool, dry, and protected from direct sunlight), Bricorr 70A provides stable and long-lasting antimicrobial protection throughout the intended shelf life of most industrial formulations.
