S-450 Silicone Leveling Agent
Structure or Component: Polyether-modified polydimethylsiloxane copolymer
Features and Applications
Similar to TEGO 450, S-450 is a high-performance specially modified polysiloxane and a representative silicone surface additive, delivering an exceptional balance of reliable flow, efficient leveling, and strong surface slip properties. It is specially engineered to provide superior substrate wetting and anti-cratering performance, while effectively reducing the airflow sensitivity of coating systems during the drying process.
By actively preventing the formation of Bénard cells (vortices), this additive ensures a flawless, uniform coating surface with enhanced gloss and consistent pigment orientation. It significantly boosts the slipperiness, scratch resistance, and anti-blocking characteristics of the dried coating film, without compromising recoatability or inter-coat adhesion.
Boasting high compatibility across a wide range of formulation systems, S-450 is an ideal choice for solvent-based, solvent-free, and waterborne coating applications alike.
