BYK DISPERBYK-192 Wetting Dispersans Agents

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

Effect of BYK DISPERBYK-192 Wetting Dispersans Agents

  1. Steric Stabilization - Prevents co-flocculation via spatial hindrance and charge equalization for effect pigments

  2. Dual Compatibility - Works in both resin-free and resin-containing grinding systems

  3. Eco-Formulation - 100% active content, free of VOC (<1500 ppm) and solvents

  4. Optical Enhancement - Improves gloss, transparency (organic pigments), and hiding power (inorganics)

  5. Process Adaptability - Reduces viscosity by 30-50% for higher pigment loading (up to 60% for concentrates)

Typical Applications of BYK DISPERBYK-192 Wetting Dispersans Agents

  1. Architectural Coatings - White paints with BYK-154 for TiO₂ stabilization

  2. Automotive Finishes - Metallic basecoats requiring flake orientation

  3. Printing Inks - Flexographic/gravure inks for packaging films

  4. Thermoplastics - PET color masterbatches with fatty acid ester carriers

  5. Gel Coats - Unsaturated polyester systems for pigment stabilization
