Q1: What is Dow KATHON LXE Biocide and how does it differ from other KATHON biocides?
A: Dow KATHON LXE Biocide is a broad-spectrum, liquid preservative formulated for use in water-based industrial products. It combines isothiazolinone actives with a proprietary stabilizing system to deliver enhanced stability and compatibility in challenging formulations—particularly those with high pH, elevated temperature, or complex surfactant systems—compared to earlier KATHON variants.
Q2: In which types of products is KATHON LXE typically used?
A: It is widely employed in water-based industrial maintenance and process fluids—including metalworking fluids, cleaning concentrates, latex emulsions, adhesives, and architectural coatings—where long-term microbial control is required without compromising product stability or performance.
Q3: How should KATHON LXE be added to a formulation?
A: For optimal performance and stability, KATHON LXE Biocide should be added late in the manufacturing process, after pH adjustment and cooling, and preferably under gentle agitation. It is generally compatible with most anionic, nonionic, and amphoteric surfactants, but compatibility testing is recommended for highly reactive or oxidizing systems.
Q4: Does KATHON LXE require special handling or safety precautions?
A: Yes—like all isothiazolinone-based biocides, KATHON LXE requires appropriate personal protective equipment (PPE) during handling, including gloves and eye protection. It is classified as a skin sensitizer and may cause irritation; therefore, occupational exposure should be minimized per standard industrial hygiene practices.
