A highly effective deflocculating additive, designed to enhance the performance of ceramic bodies and glazes. Its action is based on the ability to bind metallic ions, particularly calcium (Ca²⁺) and magnesium (Mg²⁺), which typically interfere with the deflocculation process, thereby ensuring more stable and workable suspensions.

In addition to promoting better particle dispersion, GIESSFIX PT 91 prevents the precipitation of calcium sulfate, avoiding the formation of unwanted efflorescence on ceramic surfaces.
The result is a more homogeneous and aesthetically clean final product.
