BYK DISPERBYK-168 Wetting Dispersans Agents

BYK DISPERBYK-168 is an aromatic-free block copolymer Wetting Dispersans Agents for solvent-borne and solvent-free radiation-curable coatings and printing inks. Its pigment-affinic groups enable steric stabilization of organic pigments via uniform charge distribution, optimizing viscosity reduction and flow properties. Compatible with UV flexo/offset inks, it supports high pigment loading while maintaining low-VOC compliance

Effect of BYK DISPERBYK-168 Wetting Dispersans Agents

  1. Dual Stabilization - Combines steric hindrance and electrostatic effects for uniform pigment dispersion

  2. Process Efficiency - Reduces dispersion time by 30-50% and lowers millbase viscosity

  3. Optical Enhancement - Improves gloss (up to 20% increase) and transparency in UV inks

  4. Food Safety - Compliant with FDA/EU standards for packaging inks

  5. Universal Compatibility - Works with TiO₂ (5-6%), carbon black (70-140%), and organic pigments (30-90%)

Typical Applications of BYK DISPERBYK-168 Wetting Dispersans Agents

  1. UV Flexographic Inks - High-gloss packaging films with stable color consistency

  2. Industrial Coatings - Radiation-curable can/coil coatings requiring fast curing

  3. Wood Finishes - UV-curable furniture coatings with improved pigment wetting

  4. Offset Printing - Matte/semi-gloss varnishes for label protection

  5. Adhesives - Solvent-free UV adhesives with controlled rheology
