Q1: What types of microorganisms does Domal HY-607 Biocide effectively control?
A: Domal HY-607 Biocide is a broad-spectrum preservative designed to inhibit the growth of bacteria, yeasts, and molds commonly encountered in water-based industrial formulations, including cooling water systems, metalworking fluids, and latex emulsions.
Q2: Is Domal HY-607 Biocide compatible with common industrial additives such as surfactants, thickeners, and corrosion inhibitors?
A: Yes, Domal HY-607 Biocide demonstrates good compatibility with a wide range of formulation components, including nonionic and anionic surfactants, cellulose and acrylic thickeners, and many common corrosion inhibitors—though compatibility testing under actual use conditions is recommended prior to full-scale implementation.
Q3: How should Domal HY-607 Biocide be dosed in industrial water systems?
A: Dosage depends on system conditions—including water quality, temperature, organic load, and microbial challenge—but it is typically used at low concentrations. Initial treatment generally ranges from 0.1% to 2% by weight of the total system volume, followed by maintenance dosing based on regular microbiological monitoring.
Q4: Does Domal HY-607 Biocide remain effective across a broad pH range?
A: Yes, Domal HY-607 Biocide maintains stable biocidal activity across a typical operational pH range of approximately 5.0 to 9.5, making it suitable for use in neutral and mildly alkaline industrial systems without significant loss of efficacy.
