Q1: What is the primary mode of action of Lonza Isocil IG-C Fungicide?
A: Lonza Isocil IG-C Fungicide functions primarily as a broad-spectrum preservative by inhibiting essential enzymatic activity in microorganisms, thereby preventing fungal growth and spoilage in industrial formulations.
Q2: In which types of industrial systems is Lonza Isocil IG-C Fungicide commonly used?
A: It is widely applied in water-based industrial products such as metalworking fluids, latex paints, adhesives, construction chemicals, and process water systems where long-term microbial control is required.
Q3: How should Lonza Isocil IG-C Fungicide be incorporated into a formulation?
A: It is typically added during the final stage of formulation, after pH adjustment and cooling, to ensure stability and optimal performance. Compatibility testing with other ingredients is recommended prior to full-scale use.
Q4: Is Lonza Isocil IG-C Fungicide suitable for use in products requiring regulatory compliance for indirect food contact?
A: Lonza Isocil IG-C Fungicide is designed for industrial applications and is not intended for direct or indirect food-contact uses unless explicitly authorized under applicable regional regulations and supported by specific technical documentation.
Q5: What storage conditions are recommended to maintain product efficacy?
A: Store in original, tightly sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and strong oxidizing agents. Avoid freezing, as prolonged exposure to low temperatures may affect physical consistency and performance.
