Q1: What is Schülme Grotan OK Biocide primarily used for?
A: Schülme Grotan OK Biocide is a broad-spectrum preservative formulated for use in water-based industrial coatings, adhesives, sealants, and construction chemicals to prevent microbial growth during storage and in the dried film.
Q2: Is it compatible with common paint and coating formulations?
A: Yes, Schülme Grotan OK Biocide demonstrates good compatibility with a wide range of acrylic, styrene-acrylic, vinyl acetate, and polyurethane dispersions, as well as with common thickeners, surfactants, and pH adjusters typically found in architectural and industrial coatings.
Q3: How should it be dosed in formulations?
A: Dosage depends on formulation composition, raw material bioburden, and intended application conditions. It is typically used at low concentrations, generally ranging from 0.1% to 2% by weight of the final product, with optimal levels determined through challenge testing and stability assessment.
Q4: Does it provide both bactericidal and fungicidal activity?
A: Yes, Schülme Grotan OK Biocide delivers effective control against a broad spectrum of bacteria, yeasts, and molds, supporting long-term preservation of liquid formulations and contributing to dry-film protection in certain applications.
Q5: Are there any handling or safety considerations during incorporation?
A: As with all biocidal actives, appropriate personal protective equipment (PPE) such as gloves and eye protection should be worn during handling. It is recommended to add Schülme Grotan OK Biocide late in the manufacturing process, after pH adjustment and under moderate agitation, to ensure uniform dispersion and preserve efficacy.
