主要特点与优势

  • Provides exceptional steric stabilization in aliphatic hydrocarbons and non-polar organic solvent systems.
  • Significantly reduces mill-base viscosity, enabling higher pigment loading and improved manufacturing throughput.
  • Enhances color development, transparency, and tinting strength by ensuring optimal pigment de-agglomeration.
  • Improves final film gloss and prevents haze in high-solids solvent-borne coatings and finishes.
  • Broad compatibility with low-polarity resins including long-oil alkyds, polyolefins, and thermoplastic acrylics.
  • Prevents common coating defects such as pigment flooding, floating, and sedimentation during storage.
  • Reduces energy consumption during the grinding stage by lowering the required mechanical shear force.
规格

技术亮点

  • Chemical Composition: Advanced polymeric block copolymer with specialized pigment-affinic anchoring groups.
  • Active Content: Formulated at approximately 40-50% solids in a low-polarity hydrocarbon carrier.
  • Amine Value: Typically measured between 10 and 20 mg KOH/g for precise pigment interaction.
  • Density: Standardized at approximately 0.88 – 0.92 g/cm³ at 25 degrees Celsius for formulation accuracy.
  • Solubility: Fully miscible in aliphatic hydrocarbons, mineral spirits, and non-polar esters/ethers.
  • Stabilization Mechanism: Entropy-driven steric repulsion provided by extended polymeric loops and tails.
  • Recommended Dosage: 1-5% for inorganic pigments and 10-30% for high-surface-area organic pigments.
  • Storage Stability: Chemically stable under standard industrial conditions with a high flash point profile.
实际行业应用

应用领域

  • High-performance automotive refinish coatings and OEM finishes using low-polarity solvent packages.
  • Industrial wood stains and coatings where deep penetration and color uniformity are paramount.
  • Offset and gravure printing inks utilizing aliphatic hydrocarbon-based vehicles for high-speed presses.
  • Production of pigment concentrates and liquid colorants for non-polar plastic masterbatch applications.
  • Stabilization of solid additives and friction modifiers in mineral oil-based lubricants and greases.
  • High-solids air-drying alkyd paints for heavy-duty marine and architectural protective applications.
  • Universal colorants designed for seamless integration into non-polar solvent-based architectural paint bases.
  • Dispersion of inorganic fillers like calcium carbonate and TiO2 in thermoplastic polyolefin matrices.
