Q1: What is Dow AMICAL Biocide primarily used for?
A: Dow AMICAL Biocide is a broad-spectrum antimicrobial agent designed to protect water-based industrial formulations—such as adhesives, coatings, construction chemicals, and cleaning products—from microbial degradation during storage and in-use conditions.
Q2: Is Dow AMICAL Biocide compatible with common formulation ingredients?
A: Yes, it demonstrates good compatibility with a wide range of surfactants, thickeners, pigments, and pH-adjusting agents typically found in neutral to mildly alkaline systems. Compatibility testing under actual formulation conditions is recommended prior to full-scale implementation.
Q3: How should Dow AMICAL Biocide be added to a formulation?
A: It is typically added during the cool-down phase of manufacturing, after high-temperature processing steps, to preserve its efficacy. Addition at or below 50°C is generally advised to avoid potential thermal degradation.
Q4: Does Dow AMICAL Biocide provide protection against both bacteria and fungi?
A: Yes, it offers effective control against a broad spectrum of Gram-positive and Gram-negative bacteria, yeasts, and molds, helping to prevent spoilage and maintain product integrity over time.
Q5: What is the typical dosage range for Dow AMICAL Biocide in finished products?
A: Dosage depends on formulation requirements, challenge level, and regulatory considerations, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—based on extensive laboratory and field experience.
