Product Information

Product features and advantages

VOK®- AP CK XR is a specially selected and activated bentonite product. It is highly swelled in water and shows obvious thixotropic thickening effect.

VOK®- AP CK XR prevents heavy pigments/fillers from settling and introduces yield values into the system.

German technical backgroundVOK®- AP CK XR is a pure inorganic substance, which is stable to dilute acid and alkali.  VOK®-AP CK XR  The gel produced by can also withstand oxidation or microbial degradation. VOK®- AP CK XR is compatible with most lotion, pigments or fillers. High electrolyte concentration should be avoided, otherwise the gel structure will be broken. By using VOK®- AP CK XR can produce a system with stable storage. Due to the introduction of yield value and thixotropy, the application is improved.

VOK®- AP CK XR prevents heavy pigments or fillers from settling. As a thixotropic agent,  VOK®- AP CK XR reduces sagging and allows thick coat applications.
