主要特点与优势

  • Exceptional compatibility with aliphatic hydrocarbons, mineral spirits, and low-polarity paraffinic oils.
  • Superior viscosity reduction in high-solids formulations, enabling increased pigment concentration without sacrificing flow characteristics.
  • High-efficiency anchoring groups ensure strong adsorption on both organic pigments and high-surface-area carbon blacks.
  • Provides long-term colloidal stability, effectively preventing sedimentation and syneresis in stored formulations.
  • Enhances coloristic properties including transparency, tinting strength, and chromaticity by optimizing particle size distribution.
  • Maintains high gloss and surface smoothness in finished coatings by ensuring a uniform pigment dispersion.
  • Excellent thermal stability, making it suitable for high-temperature plastic processing and automotive stoving finishes.
  • Broad resin compatibility including alkyds, acrylics, and polyolefins.

技术亮点

  • Chemical Composition: Polymeric dispersing agent with pigment-affinic functionalities.
  • Appearance: Transparent to slightly hazy amber viscous liquid.
  • Active Content: 40% to 50% non-volatile matter by weight.
  • Solvent Medium: Aliphatic hydrocarbon or low-aromatic solvent blend.
  • Acid Value: Typically 10 – 20 mg KOH/g depending on specific batch neutralization.
  • Amine Value: 15 – 25 mg KOH/g, providing balanced anchoring for acidic and neutral pigments.
  • Density: Approximately 0.88 – 0.95 g/cm³ at 25°C.
  • Flash Point: Minimum 40°C (closed cup), requiring standard flammable liquid handling protocols.
  • Recommended Dosage: 1-5% for inorganic pigments and 15-40% for organic pigments and carbon black based on pigment weight.
  • Solubility: Fully miscible in non-polar solvents; insoluble in water.
实际行业应用

应用领域

  • Solvent-borne industrial coatings requiring high gloss and durability in harsh environments.
  • Automotive refinish paints where precise color matching and stability are critical.
  • High-grade architectural enamels and wood stains based on long-oil or medium-oil alkyd resins.
  • Flexographic and gravure printing inks for flexible packaging applications.
  • Concentrated pigment pastes and universal colorants for oil-based systems.
  • Plastic masterbatches and liquid colorants for polyolefins such as PE, PP, and PS.
  • Carbon black dispersions used in high-quality sealants and non-polar adhesives.
  • Agricultural chemical formulations where stable oil-based suspensions of active ingredients are required.
  • Lubricant and grease additives for maintaining solid lubricant dispersion under shear.
