Q1: What makes BYK-3455 different from fluorinated silicone surfactants?
A: BYK-3455 is a fluorine-free silicone surfactant designed to deliver effective surface tension reduction and substrate wetting without incorporating perfluoroalkyl substances (PFAS), supporting regulatory compliance and sustainability goals in coatings, inks, and adhesives.
Q2: In which types of formulations is BYK-3455 most commonly used?
A: It is widely applied in water-based and solvent-borne industrial coatings, UV-curable systems, and printing inks—particularly where low foam, good leveling, and reliable substrate wetting on low-energy surfaces (e.g., plastics, treated metals) are required.
Q3: How does BYK-3455 affect foam behavior during formulation and application?
A: BYK-3455 is formulated to minimize foam generation and stabilize against excessive foaming, making it suitable for high-shear processes such as grinding, mixing, and high-speed coating applications.
Q4: Is BYK-3455 compatible with other additives like defoamers or rheology modifiers?
A: Yes, BYK-3455 generally shows good compatibility with common additive classes—including non-silicone defoamers, associative thickeners, and dispersing agents—though compatibility testing under actual formulation conditions is recommended.
Q5: What is the typical dosage range for optimal performance?
A: Dosage depends on the specific system and performance requirements, but BYK-3455 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight of the total formulation.
