Q1: What types of microorganisms does MERGAL 530A effectively control?
A: MERGAL 530A is a broad-spectrum biocide formulated to inhibit the growth of bacteria, fungi, and yeasts commonly encountered in water-based industrial formulations, including Pseudomonas spp., Bacillus spp., Aspergillus niger, and Candida albicans.
Q2: In which product categories is MERGAL 530A typically used?
A: It is widely applied in water-based paints and coatings, adhesives, sealants, construction chemicals, metalworking fluids, and other aqueous industrial systems where long-term microbial stability is required during storage and use.
Q3: How stable is MERGAL 530A under varying pH and temperature conditions?
A: MERGAL 530A demonstrates good stability across a typical formulation pH range of 4–10 and maintains efficacy under standard ambient and moderately elevated storage temperatures. Performance may be reduced under strongly alkaline conditions or prolonged exposure to high heat during processing.
Q4: Is MERGAL 530A compatible with common thickeners, surfactants, and co-biocides?
A: Yes — it exhibits broad compatibility with associative and non-associative thickeners, anionic and nonionic surfactants, and many commonly used co-biocides such as isothiazolinones and formaldehyde releasers. Compatibility testing in the final formulation is still recommended to confirm stability and performance.
