BYK-359 Leveling Agent

BYK-359 is a high-quality surface leveling agent under BYK brand, formulated as polyacrylate, specially developed for solvent-borne, solvent-free and powder coating systems. It has both high-efficiency leveling and defoaming effects, only slightly reduces surface tension, can effectively prevent defects such as craters and fish eyes, improves film gloss and distinctness of image

Features Of BYK-359 Leveling Agent

  1. Strong leveling and defect inhibition - Optimizes film leveling, forms long-wave effect, effectively prevents craters and fish eyes defects

  2. Excellent defoaming and deaerating - Has both deaerating and defoaming effects, completely eliminates bubbles inside and on the film surface

  3. Low tension without affecting recoat - Only slightly reduces surface tension, does not damage recoatability and interlayer adhesion

  4. Outstanding high-temperature stability - Excellent thermal stability, can withstand temperatures up to 240℃, suitable for baking processes

  5. Compatible and easy to add - Excellent compatibility, low viscosity and easy to add, can be added at any production stage

Typical Applications Of BYK-359 Leveling Agent

  1. Industrial coatings - Suitable for various industrial coatings, improves leveling and gloss, prevents crater defects

  2. Can coatings - Used in can coating, optimizes film uniformity, ensures coating durability

  3. Powder coatings - Suitable for powder coatings, especially powder clear coats, improves distinctness of image

  4. Solvent-free coatings - Used in solvent-free coating systems, exerts dual effects of leveling and defoaming

  5. Coil coatings - Suitable for coil coatings, optimizes leveling performance, improves coating surface texture
