主要特点与优势

  • Dynamic Surface Tension: Provides exceptionally low dynamic surface tension for rapid substrate coverage.
  • Anti-Crater Performance: Effectively prevents surface defects caused by substrate contamination or low surface energy.
  • Low Foaming Profile: Exhibits minimal foam stabilization, reducing the need for excessive defoamers.
  • Substrate Versatility: Performs excellently on plastics, films, and metal surfaces where traditional wetting agents fail.
  • Intercoat Adhesion: Optimized polyether modification ensures that subsequent coating layers bond securely without delamination.
  • High Efficiency: Concentrated formula allows for low dosage levels, minimizing costs.
  • Improved Leveling: Enhances flow properties for a smoother finish.
  • Eco-Friendly: VOC-free and APEO-free.
