Q1: What is the primary mode of action for Dow 2000 Biocide?
A: Dow 2000 Biocide functions primarily as a broad-spectrum antimicrobial agent that disrupts microbial cell membranes and interferes with essential metabolic processes, leading to rapid inactivation of bacteria, fungi, and algae.
Q2: In which types of industrial formulations is Dow 2000 Biocide commonly used?
A: It is widely incorporated into water-based industrial products such as metalworking fluids, latex paints, adhesives, construction chemicals, and cleaning concentrates—particularly where long-term preservation against microbial spoilage is required during storage and use.
Q3: Is Dow 2000 Biocide compatible with common surfactants and thickeners?
A: Yes, it demonstrates good compatibility with a wide range of anionic, nonionic, and amphoteric surfactants, as well as common rheology modifiers including associative thickeners and cellulose derivatives—though compatibility testing under actual formulation conditions is recommended.
Q4: How should Dow 2000 Biocide be added to a formulation?
A: It is typically added during the cool-down phase or post-emulsification stage to avoid thermal degradation. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight, adjusted based on challenge testing and end-use conditions.
