BYK® -347

Polyether modified polysiloxane. Acts as a silicone based surface additive to improve substrate wetting in aqueous systems. Provides a strong reduction of surface tension. Imparts very good substrate wetting and good flow/leveling. Does not increase surface slip or impairs recoatability. Exhibits only minor activity at the interface paint/air due to its chemical structure. Improves printability as well as application of packaging coatings. Used in aqueous coatings and printing inks.
