Product features and advantages
After stirring in the coating system, the additive forms a three-dimensional network structure. The resulting thixotropic flow behavior is very suitable for preventing sedimentation and synergistically increasing the resistance to sagging without damaging the leveling. Liquid auxiliary, easy to handle. No specific pH adjustment or temperature control is required during the adding process.
