Q1: What is the primary function of Croda Multiwet BD in industrial formulations?
A: Croda Multiwet BD is a high-performance, non-ionic wetting agent designed to rapidly reduce surface tension and promote uniform substrate wetting—especially on low-energy or difficult-to-wet surfaces such as plastics, pigments, and fillers. It enhances dispersion stability and interfacial adhesion without compromising formulation compatibility or performance.
Q2: Is Croda Multiwet BD suitable for water-based systems?
A: Yes, it is fully compatible with aqueous systems—including waterborne coatings, inks, agrochemical concentrates, and cleaning formulations—and demonstrates excellent hydrolytic stability across a broad pH range (typically pH 4–10).
Q3: How does Croda Multiwet BD compare to traditional alkylphenol ethoxylates (APEOs)?
A: Croda Multiwet BD is an APEO-free, readily biodegradable alternative that delivers comparable or superior wetting efficiency while meeting evolving regulatory expectations and sustainability goals. Its non-ionic structure avoids endocrine-disruption concerns associated with APEOs.
Q4: What is the typical dosage range for Croda Multiwet BD in finished products?
A: Dosage depends on the specific formulation and desired performance, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—making it both cost-effective and efficient in reducing surfactant load.
Q5: Can Croda Multiwet BD be used alongside other surfactants or additives?
A: Yes, it exhibits good compatibility with anionic, non-ionic, and amphoteric surfactants, as well as common rheology modifiers, defoamers, and biocides—enabling flexible formulation design without significant risk of phase separation or performance loss.
