主要特点与优势

  • Universal Compatibility: Seamlessly integrates with waterborne UV, solvent-based, and 100% solid UV-curable systems.
  • Viscosity Reduction: Drastically lowers mill-base viscosity, allowing for high-concentration pigment pastes and improved processing efficiency.
  • Enhanced Coloristics: Maximizes color development, transparency, and tinting strength by achieving narrow particle size distribution.
  • Superior Stability: Provides long-term anti-settling and anti-flocculation properties through robust steric hindrance.
  • Gloss Optimization: Significantly improves surface gloss and DOI (Distinctness of Image) in finished coatings.
  • Environmental Compliance: Low VOC and APEO-free formulation, meeting stringent modern environmental regulations for sustainable industrial production.
  • Performance Reliability: Ensures batch-to-batch consistency in demanding manufacturing.

技术亮点

  • Molecular Composition: High-molecular-weight modified block copolymer with pigment-affinic groups for maximum adsorption.
  • Active Content: Typically 40-50% active matter in a balanced aqueous/solvent carrier system.
  • Amphiphilic Nature: Dual-functional hydrophilic and lipophilic segments ensure stability across diverse polarity ranges.
  • Particle Size Control: Capable of stabilizing particles at the sub-micron and nano-scale levels.
  • Ionic Character: Non-ionic/weakly anionic nature prevents interference with sensitive UV-curing photoinitiators or resin catalysts.
  • Thermal Stability: Maintains performance during high-shear milling and high-temperature curing cycles common in industrial UV processes.
  • Low Foaming: Formulated to minimize micro-foam entrapment during high-speed dispersion.
实际行业应用

应用领域

  • Digital Inkjet Inks: Critical for stabilizing water-based and LED-UV inkjet inks to prevent nozzle clogging.
  • Flexographic Printing: Ideal for high-pigment-load flexo inks used in packaging and label printing.
  • Industrial Coatings: Utilized in UV-curable wood coatings, plastic finishes, and automotive decorative parts.
  • Screen Printing: Enhances flow and leveling in thick-film UV screen inks for electronics and signage.
  • Pigment Concentrates: Primary dispersant for universal colorants used in multi-resin industrial tinting systems.
  • Overprint Varnishes: Improves clarity and wetting in high-gloss UV-curable waterborne overprint varnishes (OPV).
  • Textile Inks: Provides excellent wash-fastness and color vibrancy in UV-curable digital textile pigments.
