DISPERBYK-1640 is a wetting and dispersing agent designed for solvent-based systems and pigment concentrates. It functions by deflocculating pigments through steric hindrance, thereby enhancing key properties such as gloss, color strength, and flowability. This makes it a valuable additive for optimizing pigment-based formulations across various applications.
Formulated for Specific Systems: Tailored to perform effectively in solvent-based systems and pigment concentrates, ensuring strong compatibility with these formulations.
Steric Hindrance Mechanism: Utilizes steric hindrance to break down pigment flocculates, preventing agglomeration and promoting uniform dispersion of pigments.
Enhances Critical Properties: Improves gloss for a more polished finish, boosts color strength for vibrant and consistent hues, and enhances flowability for smoother processing and application.
Baking Paints: Used in baking paint applications to eliminate boiling defects and control foam, ensuring a high-quality, smooth finish after curing.
Industrial Coatings: Ideal for a range of industrial coatings, enhancing their surface integrity, performance, and aesthetic appeal for consistent, reliable results across diverse applications.
