Silicone Leveling Agent OSi SiFOC 307 is a type of specially modified polyloxane. It offers excellent wetting property of substrate and good anti-cratering ability. It is good silicone surfactant auxiliary used in coating systems. It is for general purpose use, and can be used in different paint systems. It not only has good leveling ability, but also outstanding anti-shrinkage property.
OSi SiFOC 307 is a high-performance polyether-modified silicon leveling agent, meticulously engineered to enhance surface uniformity and optimize film formation in various coating applications. Known for its outstanding leveling properties, this agent is especially effective in minimizing surface defects such as pinholes, fisheyes, and cratering, thereby ensuring a smooth, flawless finish.

● Good compatibility with varnish.
● Provide a stronger reduction of the surface tension.
● Reduce the friction coefficient. Increase slip and improve scratch resistance.
● Good recoating and minimal influence on adhesion of coating films at suitable addition and baking temperature.
● Excellent property of anti-crater. Commonly used to replace oil-resistant agents, do not affect the environment and recoatability.
● Not suited for water-based.
● Hazy and viscous may occur at low temperatures. It would become clear and flow after being heated. This will not influence the quality.
● Excellent Leveling and Surface Smoothing: OSi SiFOC 307 effectively reduces surface tension, promoting a more even film distribution and consistent appearance.
● Enhanced Compatibility: This agent is compatible with a broad range of waterborne, solvent-borne, and UV-curable systems, making it ideal for versatile industrial applications.
● Anti-Crater Performance: Reduces cratering and other common surface irregularities for a polished, defect-free finish.
● Improved Flow Control: Designed to balance flow and control for optimized surface leveling without over-wetting.
OSi SiFOC 307 is suitable for use in automotive coatings, industrial coatings, wood finishes, and other high-performance applications that demand superior aesthetics and durability.
