APPLICATION AND PROPERTIES The addition of only a small amount of SER-AD FS 446 to the paint formulation has positive effect on the surface slip properties and mar resistance of the paint film. SER-AD FS 446 also improves the “coin-mar” resistance. (Coin-mar a term used to describe the marking of a dried coating when the milled edge of a coin or a similar metal object is rubbed against the surface of a coating). SER-AD FS 446 is recommended for use in car finishes, wood varnishes, printing inks as well as in various other industrial paints and can be used in both air-drying and stoving paint systems. In comparison to traditionally used silicones or surface modifiers, SER-AD FS 446 exhibits good compatibility and minimum side effects, such as poor recoatability. FEATURE -> CONSEQUENCE small dosage -> increased surface slip -> improved mar- resistance wide compatibility -> good alkali and acid stability SER-AD FS 446 is a polysiloxane based surfactant, compatible with a wide range of paints, including polyurethane, alkydmelamine, 2-pack acrylates, epoxies as well as nitrocellulosics, UV-curable coatings and air-drying alkyd paints. Characteristics include excellent alkali and acid stability to hydrolysis. DOSAGE The recommended dosage is 0.04 – 0.3% SER-AD FS 446, calculated on the total paint formulation. Optimum concentration varies with the specific composition and demands of the paint formulation. For maximum efficiency, the product should be added prior during the let-down stage of the paint manufacture process. As the composition and production procedures of coatings may vary it is recommended to check each application. Provides slip and mar resistance for solvent based paints. Can be used in car finishes, wood varnishes as well as in various other industrial paints and can be used in both air-drying and stoving paint systems. Exhibits minimum side effects, such as poor recoatability. Small dosage. Wide compatibility, good alkali and acid stability. Compatible with a wide range of paints, including polyurethane, alkydmelamine, 2-pack acrylates, epoxies as well as nitrocellulosics, UV-curable coatings and air-drying alkyd paints. Recommended usage level: 0.04 – 0.3%, calculated on the total paint formulation. Should be added prior during the let-down stage of the paint manufacture process.
