主要特点与优势

  • Superior Levelling Performance: Drastically reduces “orange peel” effects and surface waviness by evening out surface tension gradients.
  • Non-Silicone Composition: Eliminates risks of intercoat adhesion failure and allows for easy overpainting or recoating without intensive sanding.
  • Clarity and Gloss: Enhances the Depth of Image (DOI) and maintains high transparency in clearcoat applications without haze.
  • Broad Compatibility: Demonstrates excellent solubility in a wide range of polar and non-polar solvent-borne resin systems.
  • Defoaming Synergy: Assists in the release of micro-bubbles and prevents pinholing during high-speed application processes.
  • Thermal Stability: Maintains functional integrity during high-temperature industrial baking cycles.

技术亮点

  • Chemical Nature: Solution of a modified polyacrylate polymer.
  • Active Content: Formulated at 50% to 70% non-volatile matter in aromatic or ester-based solvent carriers.
  • Refractive Index: Precision-matched to standard resin systems to ensure optical purity in high-gloss topcoats.
  • Density: Approximately 0.95–1.05 g/cm³ at 25°C, allowing for rapid and uniform incorporation.
  • Low Acid Value: Typically <3 mg KOH/g, ensuring zero interference with acid-catalyzed curing mechanisms or metallic pigments.
  • Effective Dosage: Highly efficient at concentrations between 0.1% and 1.0% based on total formulation weight.
  • Appearance: Clear to slightly yellowish liquid.
实际行业应用

应用领域

  • Automotive Coatings: Essential for OEM basecoats and clearcoats to achieve a premium, defect-free “Class A” finish.
  • Industrial Finishes: Utilized in machinery and heavy equipment coatings for robust surface protection and aesthetic consistency.
  • Wood Coatings: Enhances flow and levelling in solvent-based furniture lacquers and high-performance UV-curable wood finishes.
  • Coil and Container: Provides uniform film formation in high-speed roller coating applications for metal packaging and siding.
  • Plastic Coatings: Improves wetting on low-energy plastic substrates for consumer electronics and automotive interiors.
  • Protective Coatings: Applied in marine and anti-corrosive systems to ensure a pinhole-free, continuous protective barrier.
