Q1: What is the primary mode of action of Schülme Parmetol TK2 Biocide?
A: Schülme Parmetol TK2 Biocide functions as a broad-spectrum preservative through membrane disruption and interference with essential microbial metabolic processes, effectively controlling bacteria, yeasts, and molds in industrial formulations.
Q2: In which types of industrial systems is Parmetol TK2 typically applied?
A: It is commonly used in water-based industrial products such as metalworking fluids, latex paints, adhesives, construction slurries, and cleaning concentrates—particularly where long-term microbiological stability and low volatility are required.
Q3: How should Parmetol TK2 be incorporated into a formulation?
A: It is recommended to add Parmetol TK2 during the cool-down phase or after emulsification, under mild agitation, to ensure uniform dispersion. Pre-dilution in water or a compatible solvent may improve compatibility in sensitive systems.
Q4: Is Parmetol TK2 compatible with common industrial additives?
A: Yes—it demonstrates good compatibility with anionic, nonionic, and cationic surfactants, thickeners, corrosion inhibitors, and most pH stabilizers across a typical working range of pH 5–10. Compatibility testing under actual formulation conditions is always advised.
Q5: What safety and handling considerations apply to Parmetol TK2?
A: As with all biocidal agents, appropriate personal protective equipment (PPE) including gloves and eye protection should be worn during handling. Avoid inhalation of mists or prolonged skin contact. Full safety information is provided in the Safety Data Sheet (SDS), which must be consulted prior to use.
