Product features and advantages

German technical background VOK®- AP CK produces thixotropic flow behavior. Due to its high efficiency of sedimentation prevention, the processability and storage stability are improved. In addition, higher coating thickness can be obtained by reducing sagging tendency after construction. VOK ®- AP CK is an inorganic substance, which is stable to dilute acid and alkali. The stability of dilute acid should be checked one by one in each case.
