Biaomei SiFast SF-732 Leveling Agent

Biaomei SiFast SF-732 is a dual-system low-foaming high-efficiency leveling agent under Biaomei brand, which is polyether-modified polysiloxane, a highly compatible organosilicon non-ionic surfactant (medium molecular weight polymer), specially developed for water-based and solvent-based coating systems. It can significantly reduce system surface tension,

Features Of Biaomei SiFast SF-732 Leveling Agent

  1. Excellent low foaming and foam stability - Low foaming and low foam stability, quickly eliminate dispersed foam, avoid paint film pinholes and bubble defects

  2. High efficiency leveling and wetting - Fast leveling speed, superior interface wetting performance, improve paint film flatness and adhesion

  3. Small dosage and easy operation - Small dosage, simple operation, efficiently adapt to various construction scenarios, reduce use cost

  4. Better slip than similar products - In alkyd systems, with other performances unchanged, slip is significantly better than BYK-333 similar products

  5. Excellent dual-system compatibility - Suitable for water-based and solvent-based coating systems, good resin compatibility and strong versatility

Typical Applications Of Biaomei SiFast SF-732 Leveling Agent

  1. Thermoplastic acrylic coatings - Adding 0.1-0.5% helps matte powder arrange directionally and enhances paint film slip

  2. Alkyd PU coatings - Adding 0.05-0.3% has excellent leveling and significantly improves paint film feel and texture

  3. UV coatings - Adding 0.05-0.3% efficiently improves leveling and strongly enhances paint film slip

  4. Water-based industrial coatings - Suitable for various water-based industrial paints, low-foaming leveling, reducing foam defects in water-based systems

  5. Solvent-based wood coatings - Used in solvent-based wood paints, optimize leveling and wetting, highlight the natural texture of wood
