Starch Ceramic Binder
CAS Number: 9005-25-8
Pregelatinized and modified starches are cost-effective binders for traditional ceramic tile, sanitaryware, and refractory applications. Starch provides high green strength, good plasticity, and clean burnout in the 300–500 °C range. Modified dextrin and corn starch grades offer improved cold-water dispersibility and controlled viscosity for various forming processes.
