Choosing the Right STPP for Glaze — Our STPP LKS & HLP

Choosing the right STPP for glaze isn’t just a chemistry decision — it directly impacts glaze flow, stability, and the final surface quality of tiles. Generic industrial STPP often fails to deliver consistent results, which is why ceramic producers increasingly turn to specialised grades engineered specifically for glaze systems. Rajiv Cera’s STPP LKS and HLP were developed in partnership with Aditya Birla Chemicals – Thailand, combining global chemical expertise with real-world ceramic application knowledge. These grades are created to provide exactly what a glaze slurry needs: predictable flow, stable viscosity, and zero settling. Sharper, Cleaner Deflocculation Rajiv STPP offers a controlled deflocculation effect that disperses particles quickly and evenly. Manufacturers achieve the required viscosity with lower dosage, faster mixing, and better flow during milling and application. This saves time, reduces chemical costs, and improves batch-to-batch consistency. - A More Homogeneous Glaze Slurry - A good glaze must remain uniform from start to finish. Rajiv STPP creates a smooth, stable suspension where particles stay dispersed. This prevents hard settling, separation, and viscosity swings — common problems when using low-quality STPP. - Improved Grinding Efficiency - One of the biggest advantages of Rajiv STPP is its impact on grinding. When the glaze is properly deflocculated early, the mill runs more efficiently. Users report shorter milling cycles, better particle size distribution, and overall lower energy consumption. Whether the glaze is circulating for hours or sitting in a tank overnight, Rajiv STPP maintains stability. The slurry stays consistent, flows smoothly, and fires with fewer defects. This reliability is a major reason why these grades are preferred by large tile manufacturers. This gives manufacturers tighter control, fewer rejects, and superior surface finish in the final product.
