TEGO reports that its VariPlus LK lowers VOC content in pigment concentrates and coatings formulations, while helping to reduce emissions.   Until now, pigment concentrates have generally had a high VOC content, which largely determines the final VOC content of colored coatings. To reduce this high VOC content, Evonik has developed TEGO VariPlus LK grinding resin. The new resin reduces the viscosity of the concentrate, thus permitting optimized pigment loading. Used in combination with TEGO Di...
