BYK-399 Leveling Agent

BYK-399 is a high-quality surface leveling agent under BYK brand, formulated as a silicone-free and fluorine-free polymer, specially developed for solvent-borne and baking coating systems. It has excellent leveling performance, can moderately reduce coating surface tension, improve substrate wettability, slightly inhibit crater defects, and has defoaming effect at high addition levels

Features Of BYK-399 Leveling Agent

  1. Silicone-free and fluorine-free formula - No silicone or fluorine, avoiding silicone contamination, suitable for silicone-sensitive coating scenarios

  2. Excellent leveling effect - Optimize film flow characteristics, improve film flatness, suitable for various gloss formulations

  3. Outstanding wetting and defect inhibition - Improve substrate wetting, slightly inhibit craters, reduce surface defects

  4. Excellent defoaming and compatibility - Defoaming effect at high addition levels, no foam stabilizing effect, excellent compatibility

  5. Good recoatability - Does not affect subsequent coating, suitable for multi-coat painting processes, convenient construction

Typical Applications Of BYK-399 Leveling Agent

  1. Solvent-borne industrial coatings - Suitable for various solvent-borne industrial paints, improve leveling and optimize surface texture

  2. Automotive coatings - Used in automotive coating systems, improve wettability and leveling, ensure paint surface quality

  3. Coil/can coatings - Suitable for solvent-borne coil and can coatings, improve film flatness and durability

  4. Two-component polyurethane coatings - Used in 2K PU coatings, optimize leveling and avoid defects such as craters

  5. Baking coatings - Suitable for various baking coatings, high temperature resistance, stable leveling performance
