Broad-spectrum fungicidal activity against key spoilage yeasts and molds in water-based industrial systems.
Low-odor, non-volatile formulation designed for stable performance in recirculating cooling water and process water applications.
Compatible with common corrosion inhibitors, scale controllers, and other water treatment additives.
Effective at low use concentrations (typically 50–200 ppm active ingredient), supporting cost-efficient dosing.
Non-oxidizing mode of action, reducing risk of material compatibility issues with elastomers and metals.
Cooling water systems in power generation and HVAC installations.
Process water circuits in paper manufacturing and textile processing.
Recirculating water systems in metalworking fluid sumps and machining operations.
Industrial preservative for water-based adhesives, coatings, and latex emulsions during storage.
Biocide booster in closed-loop glycol systems requiring supplemental microbial control.

Q1: What is the primary mode of action of Dow ROCIMA 562 Fungicide?
A: Dow ROCIMA 562 Fungicide functions as a broad-spectrum, non-oxidizing antimicrobial agent with activity against fungi, yeasts, and bacteria. Its efficacy stems from disruption of cellular metabolism and membrane integrity in susceptible microorganisms.
Q2: In which types of industrial formulations is Dow ROCIMA 562 typically used?
A: It is commonly incorporated into water-based industrial products such as metalworking fluids, latex paints, adhesives, construction chemicals, and cleaning concentrates—especially where long-term microbial stability and resistance to spoilage are critical.
Q3: How should Dow ROCIMA 562 be added to a formulation for optimal performance?
A: For best results, it is recommended to add Dow ROCIMA 562 during the cool-down phase of formulation, after high-temperature processing steps, and under mild agitation. Pre-dilution in water or a compatible solvent may aid uniform dispersion.
Q4: Is Dow ROCIMA 562 compatible with common biocides used in dual-preservative systems?
A: Yes, it is frequently used in combination with isothiazolinone-based or formaldehyde-releasing preservatives to broaden the antimicrobial spectrum and enhance shelf-life stability. Compatibility testing under actual formulation conditions is advised prior to full-scale implementation.
