BYK® -325

Solution of a polyether modified methylalkylpolysiloxane copolymer. Acts as a silicone based leveling agent for solvent-borne and aqueous coatings. Offers improved flow and leveling. Gives partial defoaming properties. Provides a slight reduction of surface tension. Prevents Bénard cell formation. Also prevents ghosting (wipe-marks) if recoated with the same paint. Does not causes rewetting problems and does not influences recoatability. Used in solvent-borne and aqueous coatings.
