Features and advantages

When mixed into the paint system, the additives will establish a three-dimensional structure. The thixotropic fluidity formed can prevent sedimentation, delamination and increase anti sagging performance without affecting leveling. The additive is liquid and easy to add. It is unnecessary to adjust the PH value and temperature control when adding the mixture.
