主要特点与优势

  • Superior Surface Tension Reduction: Drastically lowers dynamic surface tension to ensure complete substrate wetting and penetration.
  • Enhanced Leveling: Promotes rapid flow-out, eliminating surface imperfections like orange peel and brush marks effectively.
  • Anti-Crater Properties: Effectively prevents defects caused by contaminants or low-energy spots on various technical substrates.
  • Excellent Compatibility: Suitable for water-based, solvent-based, and UV-curable systems without causing film turbidity or haze.
  • Improved Slip: Enhances surface smoothness and scratch resistance of the dried film for better mechanical durability.
  • Minimal Foaming: Optimized molecular structure ensures high efficiency with low air entrainment during application.
  • Recoatability: Maintains inter-coat adhesion, allowing for multiple applications without requiring intensive surface sanding.
规格

技术亮点

  • Chemical Composition: High-purity polyether-modified polydimethylsiloxane copolymer designed for maximum surface activity and stability.
  • Active Content: Typically provided at 100% concentration for maximum formulation flexibility and overall cost-effectiveness.
  • Solubility Profile: Fully soluble in water, alcohols, and organic solvents like aromatics, glycols, and esters.
  • Thermal Stability: Maintains performance integrity across a wide temperature range, making it suitable for stoving enamels.
  • pH Versatility: Exhibits stable performance in both acidic and alkaline environments ranging from pH 4 to 10.
  • Viscosity: Low-viscosity liquid (200–500 mPa.s) ensuring easy incorporation and uniform distribution within the matrix.
  • Dosage Efficiency: Effective at low addition levels, typically 0.1% to 1.0% based on total formulation weight.
实际行业应用

应用领域

  • Automotive Coatings: Used in basecoats and clearcoats to achieve a mirror-like, high-gloss finish and depth.
  • Industrial Wood Finishes: Improves wetting on porous wood surfaces and prevents cratering over residual natural resins.
  • Printing Inks: Enhances dot gain and flow in high-speed flexographic, gravure, and screen-printing ink applications.
  • Waterborne Paints: Essential for reducing surface tension in latex systems to prevent crawling on plastic substrates.
  • UV-Curable Coatings: Provides rapid wetting and leveling during high-speed curing processes in electronics and packaging.
  • Protective Metal Coatings: Ensures uniform coverage over oily or poorly prepped metal substrates in industrial maintenance.
  • Leather Finishing: Enhances the surface feel and uniformity of topcoats on treated synthetic and natural leather.
