S-313 Silicone Leveling Agent

S-313 Silicone Leveling Agent

Structure or Component: Polyether-modified polydimethylsiloxane copolymer

Features and Applications

S-313 is a high-performance silicone surface additive engineered to provide superior slip, wear resistance, and leveling properties across UV curable, solvent-based, and aqueous systems. By significantly reducing the coefficient of friction, it enhances surface smoothness, scratch resistance, and anti-blocking performance while ensuring rapid leveling and improved gloss.

Its high compatibility makes it an ideal solution for both pigmented and matte finishes, offering a premium tactile feel and robust protection without compromising recoatability or inter-coat adhesion.
