主要特点与优势

  • Exceptional steric stabilization in non-polar mediums including aliphatic hydrocarbons and mineral oils.
  • High efficiency in reducing the viscosity of concentrated pigment dispersions, allowing for higher solids loading.
  • Significant improvement in color strength, transparency, and gloss for both organic and inorganic pigments.
  • Outstanding compatibility with long-oil alkyd resins, polyolefins, and low-polarity thermoplastic elastomers.
  • Reduces milling time significantly by accelerating particle wetting and de-agglomeration processes during production.
  • Excellent thermal stability, preventing yellowing or chemical degradation during high-temperature processing such as extrusion or injection molding.
规格

技术亮点

  • Chemical Composition: Polymeric fatty acid derivative with specialized anchoring groups for pigment surfaces.
  • Active Content: Minimum 98% non-volatile matter, ensuring high potency and minimal solvent interference.
  • Acid Value: Typically ranges between 10-20 mg KOH/g to optimize interaction with basic pigment surfaces.
  • Solubility: Completely miscible in n-hexane, toluene, white spirit, and paraffinic base oils.
  • Density: Approximately 0.92 g/cm³ at 25°C, facilitating easy integration into lightweight industrial formulations.
  • Appearance: Clear, amber viscous liquid at room temperature, facilitating pourability and accurate dosing.
  • Recommended Dosage: Between 1% to 10% based on pigment weight depending on surface area.
实际行业应用

应用领域

  • Formulation of high-quality solvent-based offset and gravure printing inks for packaging and publication.
  • Manufacturing of color masterbatches for polyolefins like PE and PP, ensuring uniform color distribution.
  • Stabilization of carbon black and titanium dioxide in automotive refinish and industrial coatings.
  • Lubricant additives for oil-based drilling fluids to maintain suspension of weighting agents and cuttings.
  • Pigment pastes for long-oil alkyd architectural paints, providing long-term storage stability and anti-settling.
  • Specialty wood stains and preservatives where deep penetration into hydrophobic substrates is required.
  • Production of magnetic recording materials and electronic pastes requiring precise particle arrangement in non-conductive media.
