主要特点与优势

  • Drastic Viscosity Reduction: Enables significantly higher filler loadings without compromising flow or pumpability.
  • Superior Surface Wetting: Rapidly displaces air and moisture from the filler surface to ensure complete encapsulation.
  • Steric Stabilization: Prevents flocculation and particle settling during long-term storage or processing.
  • Improved Surface Finish: Eliminates surface defects and ‘orange peel’ effects by ensuring homogenous particle distribution.
  • Enhanced Throughput: Reduces mixing time and energy consumption by accelerating the wetting process.
  • Mechanical Optimization: Improves the tensile and impact strength of the final composite through better interfacial bonding.

技术亮点

  • Functional Anchoring Groups: Designed with high affinity for mineral surfaces, including acidic and basic functional sites.
  • Low Volatility: High-solids or solvent-free liquid composition suitable for low-VOC industrial requirements.
  • Thermal Stability: Maintains chemical integrity at high processing temperatures (up to 250°C) without discoloration.
  • Broad Compatibility: Effective in various systems including unsaturated polyesters, epoxies, acrylics, and polyurethanes.
  • Dosage Efficiency: Highly concentrated formula requiring only 0.5% to 2.5% weight based on the filler content.
  • Hydrophobic Barrier: Provides a protective layer on fillers, reducing water absorption in the finished product.
实际行业应用

应用领域

  • Sheet Molding Compounds (SMC) and Bulk Molding Compounds (BMC) for automotive and electrical housings.
  • Synthetic Marble and Quartz: High-load mineral casting for kitchen countertops and sanitary ware.
  • Flame Retardant Systems: Managing high loadings of Alumina Trihydrate (ATH) or Magnesium Hydroxide.
  • Industrial Coatings: High-build primers and heavy-duty anti-corrosion coatings with high pigment volume concentration.
  • Pultrusion Processes: Enhancing the wetting of glass fibers and fillers in continuous profile manufacturing.
  • PVC Plastisols: Improving the rheology of highly filled vinyl flooring and coating formulations.
