Q1: What types of fungi does Lonzaserve 240 effectively control?
A: Lonzaserve 240 is formulated to provide broad-spectrum protection against common spoilage and contamination fungi, including Aspergillus, Penicillium, Cladosporium, and yeasts such as Candida and Rhodotorula. Its efficacy is particularly valued in water-based industrial systems where microbial growth poses stability or performance risks.
Q2: In which industrial applications is Lonzaserve 240 typically used?
A: This fungicide is widely applied in water-miscible metalworking fluids, industrial cleaning formulations, latex emulsions, adhesives, and water-based paints and coatings—especially where long-term microbiological stability and resistance to fungal bloom are critical during storage and use.
Q3: How should Lonzaserve 240 be incorporated into a formulation?
A: It is typically added during the final stage of manufacturing, after pH adjustment and cooling, to ensure optimal stability and activity. Due to its water-miscibility and compatibility with many anionic, nonionic, and cationic surfactants, it can be directly dosed or pre-diluted in water or compatible solvents before blending.
Q4: Is Lonzaserve 240 compatible with common biocides used for bacterial control?
A: Yes, Lonzaserve 240 is generally compatible with isothiazolinones (e.g., BIT, MIT), formaldehyde donors, and other broad-spectrum preservatives when used at recommended levels. Synergistic combinations are often employed to achieve comprehensive antimicrobial protection, though compatibility testing under actual formulation conditions is advised.
