It is used in coatings and printing inks. Silicone additive to improve surface properties in all solvent-based, solvent-free and aqueous coatings. Solvent-free version of BYK®-300. Especially used in systems in which solvent-free additives are requested or where a requirement for a special solvent exists. BYK®-302 reduces surface tension and therefore provides better substrate wetting. At the same time surface slip is increased and anti-blocking properties are improved. Formation of Bénard cells is avoided, levelling and gloss are improved. BYK®-302 is used in all aqueous, solvent-based and solvent-free printing inks. It increases surface slip, reduces the abrasion and gives anti-blocking properties. At the same time, gloss and levelling are improved. The additive is especially used in systems in which solvent-free additives are requested or where a requirement for a special solvent exists. Polyether modified poly-dimethyl-siloxane. Used in coatings and printing inks. Provides better substrate wetting. Offers increased surface slip. Possesses improved anti-blocking properties. Exhibits improved levelling and gloss.
