Q1: What types of microorganisms does Domal HY-606D Biocide effectively control?
A: Domal HY-606D Biocide is a broad-spectrum preservative designed to inhibit the growth of bacteria, yeasts, and molds commonly encountered in water-based industrial formulations, including Pseudomonas spp., Staphylococcus aureus, Candida albicans, and Aspergillus niger.
Q2: In which product categories is Domal HY-606D Biocide typically used?
A: It is widely applied in water-based paints and coatings, adhesives, construction chemicals, metalworking fluids, and cleaning concentrates—where long-term microbial stability and compatibility with common formulation ingredients are essential.
Q3: Is Domal HY-606D Biocide compatible with common thickeners, surfactants, and pH adjusters?
A: Yes, Domal HY-606D Biocide demonstrates good compatibility with non-ionic and anionic surfactants, associative and cellulosic thickeners, and typical pH buffers such as AMP-95 and sodium hydroxide, across a pH range of approximately 4–10.
Q4: How should Domal HY-606D Biocide be added during formulation?
A: It is recommended to add Domal HY-606D Biocide late in the manufacturing process—after high-shear mixing and cooling—to minimize thermal degradation and ensure optimal preservation performance. Pre-dilution with water or a compatible solvent may improve dispersion in viscous systems.
Q5: What is the typical dosage range for effective preservation?
A: Dosage depends on formulation complexity, raw material bioburden, and storage conditions, but Domal HY-606D Biocide is generally effective at concentrations ranging from 0.1% to 2.0% by weight of the final product.
