Ayanabond™ RX is a thermally durable hydrous kaolin designed for monolithic refractory formulations, especially in castables, gunning mixes, and repair masses. Its structural alumina content and controlled impurities support strength retention at elevated temperatures. The lamellar particle shape aids plasticity and helps form uniform ceramic bonds on firing.
Application Portfolio
• Low-heat castables and gunning masses
• Patch and repair materials for kilns and boilers
• Non-alkaline insulation bricks
• Precast monolithics (non-critical grade)
Technical Highlights
• Al₂O₃ ~38% → ideal structural support
• Low alkalis → minimizes fluxing in high-heat zones
• Moderate shrinkage → better thermal shock resistance
• Works in blends → good with chamotte or calcined clays
• Stable firing behavior → maintains ceramic integrity
“Ayanabond™ RX helps refractory producers build heat-stable linings with confidence — resilient, cost-effective, and consistent.”
