Q1: What is the primary function of Schülme Grotan WSplus Biocide in water-based systems?
A: Schülme Grotan WSplus Biocide is a broad-spectrum preservative designed to inhibit microbial growth—including bacteria, yeasts, and fungi—in water-based industrial formulations such as coatings, adhesives, construction chemicals, and cleaning agents.
Q2: Is Schülme Grotan WSplus Biocide compatible with common thickeners and surfactants used in aqueous formulations?
A: Yes, it demonstrates good compatibility with a wide range of non-ionic and anionic surfactants, as well as associative and cellulosic thickeners commonly found in architectural and industrial coatings—though compatibility testing under actual formulation conditions is always recommended.
Q3: How should Schülme Grotan WSplus Biocide be added during manufacturing?
A: It is typically added during the cool-down phase (below 40 °C) to minimize potential degradation and ensure optimal stability. Pre-dilution with water or a compatible solvent may improve dispersion, especially in low-shear processes.
Q4: Does Schülme Grotan WSplus Biocide provide long-term preservation throughout product shelf life?
A: When applied at appropriate dosage levels and under suitable storage conditions, it delivers robust and persistent antimicrobial protection against spoilage organisms, supporting extended shelf life in finished products.
