Q1: What is the primary mode of action of Dow 7287 Biocide?
A: Dow 7287 Biocide functions primarily as a broad-spectrum antimicrobial agent effective against bacteria, yeasts, and molds. Its activity stems from disruption of microbial cell membranes and interference with essential metabolic processes, leading to rapid biocidal action in aqueous systems.
Q2: In which types of industrial formulations is Dow 7287 Biocide commonly used?
A: It is widely incorporated into water-based industrial products such as metalworking fluids, latex paints and coatings, adhesives, sealants, construction chemicals, and cleaning concentrates—where long-term preservation against microbial spoilage is required during storage and use.
Q3: How stable is Dow 7287 Biocide under typical formulation conditions?
A: Dow 7287 Biocide exhibits good hydrolytic and thermal stability across a broad pH range (approximately pH 4–10) and remains effective in formulations subjected to moderate temperature variations and extended shelf life requirements.
Q4: Is Dow 7287 Biocide compatible with common surfactants and thickeners?
A: Yes, it demonstrates broad compatibility with anionic, nonionic, and amphoteric surfactants, as well as associative and non-associative thickeners typically used in industrial and architectural coatings and maintenance formulations.
Q5: What is the typical dosage range for effective preservation with Dow 7287 Biocide?
A: Effective dosage generally ranges from 0.1% to 2% by weight in the final product, depending on formulation complexity, water activity, anticipated microbial challenge, and regulatory or customer-specific performance expectations.
