S-432 Silicone Leveling Agent
Structure or Component: Polyether-modified polydimethylsiloxane copolymer
Features and Applications
Similar to TEGO 432, S-432 is a high-performance representative silicone surface additive, specially engineered to deliver superior slip, wear resistance, and consistent leveling properties for professional coating and ink systems. It excels in efficient substrate wetting and surface smoothing, significantly reducing the surface coefficient of friction to create a highly slippery, premium tactile finish.
Beyond effectively enhancing surface gloss, this additive actively promotes the stable orientation and uniform leveling of pigments and fillers, ensuring a consistent, defect-free, and flawless final appearance. As a versatile and essential formulation component, it dramatically improves scratch resistance and long-term surface durability across water-based, solvent-based, and UV-curable applications, meeting the high standards of professional formulation needs.
