Zircon Patch - Chemically Bonded Refractory Patching Mix

VITCAS Zircon Patch Refractory Repair Compound – 1750°C

VITCAS Zircon Patch is a high-strength, chemically bonded refractory patching compound formulated for hot and cold repairs to high-temperature industrial linings. Based on zircon refractory materials and rated to 1750°C / 3180°F, it is particularly suitable for repairing compatible silica, alumina and zircon refractories in glass furnaces and other demanding thermal installations.

Supplied in a semi-dry, workable consistency, Zircon Patch is designed for localised repairs to worn, cracked or damaged refractory surfaces. Its higher moisture content, compared with Zircon Ram, supports patching applications where the material must be worked into prepared repair areas. The chemical bond provides strength during setting and subsequent high-temperature service.

Key Features and Benefits

• High Temperature Resistance: Maximum service temperature of 1750°C / 3180°F.
• Zircon-Based Formulation: High-refractoriness repair compound for demanding industrial environments.
• Chemically Bonded: Develops a strong refractory repair suitable for compatible high-temperature linings.
• Hot and Cold Repairs: Formulated for maintenance work under suitable hot or ambient-temperature conditions.
• High Strength: Designed for durable localised repairs to refractory surfaces.
• Refractory Compatibility: Suitable for repairing silica, alumina and zircon-based refractory materials.
• Semi-Dry Consistency: Allows placement and consolidation into suitable repair areas.

Applications

• Glass Furnace Crowns: Repairing worn or damaged refractory areas in glass melting furnace crowns.
• Glass Furnace Superstructures: Localised maintenance of compatible refractory brickwork and high-temperature furnace sections.
• Silica Refractory Repairs: Patching suitable silica brick linings and components.
• Alumina and Zircon Refractories: Repairing compatible high-alumina and zircon-based refractory surfaces.
• Non-Ferrous Foundry Equipment: Selected repairs to refractory-lined ladles and metal-melting equipment.
• Expansion Joint Areas: Filling specified refractory gaps where a packed, rigid repair is appropriate and thermal movement requirements are maintained.

Application and Performance Considerations

Zircon Patch is intended for localised refractory repair rather than general-purpose bricklaying. Damaged areas should be prepared back to sound refractory material, and the compound placed and consolidated to achieve adequate contact and mechanical retention.

For hot repairs, the permissible application temperature and method must follow the manufacturer's technical guidance and the site's approved maintenance procedures. The repair should be compatible with the existing refractory composition, furnace atmosphere and operating conditions.

Please note: The 1750°C rating refers to maximum service temperature, not permissible application temperature. Zircon Patch is not a flexible expansion-joint sealant or a substitute for replacing structurally unsound refractory linings. Hot repairs require specialist assessment and appropriate safety procedures.
