Byk -031 Emulsion of paraffin-based mineral oils and hydrophobic components BYK Chemie Defoamer / Antifoaming agent >> Silicone-free >> Mineral oil Vinyl Coatings >> Waterborne Architectural / Decorative >> Exterior wall coatings water Byk® -031 is emulsion of hydrophobic components and paraffin-based mineral oil. Mineral oil defoamer for emulsion paints, emulsion plasters, exterior wall paints and emulsion adhesives to defoam during production and application. The defoamer is stable upon storage, resistant to yellowing from ultra-violet radiation and does not influence color acceptance and color development in tinted systems. BYK®-031 is silicone-free and used in highly filled emulsion paints with a PVC of 50-85%. For optimum incorporation, relatively high shear forces are necessary. For new formulations BYK®-032 is recommended instead of BYK®-031 because it is easier to incorporate. Emulsion of hydrophobic components and paraffin-based mineral oil. Used for emulsion paints, emulsion plasters and exterior wall paints.
