BYK DISPERBYK-192 is a solvent-free copolymer Wetting Dispersans Agents designed for aqueous coatings, printing inks, and thermoplastic color concentrates. Its pigment-affinic groups enable steric stabilization of effect pigments (e.g., metallic/flakes) and conventional pigments, ensuring homogeneous dispersion without VOC emissions. Compatible with resin-free/resin-containing systems, it optimizes viscosity reduction and storage stability
Steric Stabilization - Prevents co-flocculation via spatial hindrance and charge equalization for effect pigments
Dual Compatibility - Works in both resin-free and resin-containing grinding systems
Eco-Formulation - 100% active content, free of VOC (<1500 ppm) and solvents
Optical Enhancement - Improves gloss, transparency (organic pigments), and hiding power (inorganics)
Process Adaptability - Reduces viscosity by 30-50% for higher pigment loading (up to 60% for concentrates)
Architectural Coatings - White paints with BYK-154 for TiO₂ stabilization
Automotive Finishes - Metallic basecoats requiring flake orientation
Printing Inks - Flexographic/gravure inks for packaging films
Thermoplastics - PET color masterbatches with fatty acid ester carriers
Gel Coats - Unsaturated polyester systems for pigment stabilization
