Q1: What types of microorganisms does Lamirsa M 87.X Biocide effectively control?
A: Lamirsa M 87.X Biocide is formulated to provide broad-spectrum activity against common bacteria, yeasts, and molds frequently encountered in water-based industrial formulations, including cooling water systems, metalworking fluids, and latex emulsions.
Q2: Is Lamirsa M 87.X Biocide compatible with common formulation ingredients such as surfactants, thickeners, and pH adjusters?
A: Yes, Lamirsa M 87.X Biocide demonstrates good compatibility with a wide range of non-ionic and anionic surfactants, cellulose and acrylic thickeners, and common buffering agents across typical pH ranges (pH 5–9), though compatibility testing under actual formulation conditions is recommended prior to full-scale implementation.
Q3: How should Lamirsa M 87.X Biocide be added to a formulation for optimal performance?
A: It is typically added during the final stage of manufacturing, after pH adjustment and cooling, to minimize thermal or chemical degradation. Pre-dilution with water or a compatible solvent may improve dispersion in viscous or heterogeneous systems.
Q4: Does Lamirsa M 87.X Biocide require special handling or storage conditions?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from direct sunlight and frost. Avoid prolonged exposure to high humidity or incompatible materials such as strong oxidizers or highly alkaline substances. Standard industrial hygiene practices apply during handling.
