Vitset 85 - Refractory Mortar Ready Mixed

VITCAS Vitset 85 – High Alumina Refractory Mortar 1810°C

VITCAS Vitset 85 is a ready-mixed, air-setting high-alumina refractory mortar developed for demanding industrial applications involving extremely high temperatures. With a maximum service temperature of 1810°C / 3290°F, it is designed for setting and jointing compatible refractory bricks in high-temperature alloy processing equipment, treatment vessels and specialist furnace linings.

Formulated with approximately 81% alumina (Al₂O₃), Vitset 85 provides high refractoriness and a strong bond within suitably designed refractory brickwork. Its ready-to-use consistency supports controlled trowelling and brick-dipping applications where thin, uniform mortar joints are required.

Key Features and Benefits

• High Temperature Resistance: Maximum service temperature of 1810°C / 3290°F.
• High Alumina Content: Approximately 81% Al₂O₃ for demanding refractory applications.
• Air-Setting Mortar: Develops an initial bond at ambient temperature before exposure to heat.
• Ready-Mixed Formulation: Supplied ready for application without additional mixing with water.
• Refractory Brick Bonding: Suitable for setting and jointing compatible high-alumina refractory bricks.
• Versatile Application: Suitable for trowelling and brick-dipping methods.
• Industrial Temperature Stability: Designed for specialist refractory installations involving high-temperature processing.

Applications

• High-Temperature Alloy Processing: Jointing compatible refractory brickwork in equipment used for processing high-temperature alloys.
• Industrial Treatment Vessels: Setting refractory bricks in suitable vessels exposed to demanding thermal conditions.
• Specialist Industrial Furnaces: Construction and maintenance of high-alumina refractory linings requiring elevated service temperatures.
• High-Alumina Refractory Brickwork: Thin-joint bonding in compatible high-temperature refractory assemblies.
• Refractory Lining Maintenance: Repair and replacement of suitable mortar joints in industrial heating equipment.

Application and Performance Considerations

Vitset 85 is intended for thin-joint refractory brickwork. Apply by trowelling or dipping to clean, compatible refractory surfaces, maintaining the specified mortar joint thickness. The manufacturer's technical data recommends joints of less than 3 mm.

Allow the mortar to air-set and dry before introducing heat progressively in accordance with the refractory lining specification. Mortar selection should account for brick composition, operating atmosphere, chemical exposure and thermal cycling.

Please note: The 1810°C rating is the mortar's maximum service temperature and does not increase the temperature capability of the refractory bricks. Vitset 85 should be selected according to the complete lining design and operating conditions.
