Fiberfrax® QF180 Refractory Coating
High-Performance Surface Protection up to 1260°C

Fiberfrax® QF180 is a high-performance, air-setting refractory coating designed for extreme thermal and chemical environments. Applied by brush or spray, it forms a durable barrier that resists flame erosion, molten metal contact, and chemical degradation.

Ideal for bonding and coating Fiberfrax Variform ceramic insulation and Fiberfrax XJ1 putty, this coating enhances thermal protection and extends the life of insulation in high-temperature operations.

Key Benefits:

• Resists Erosion & Chemical Attack: Ideal for furnaces, boilers, and thermal processing equipment
• Non-Wetting to Molten Metals: Withstands contact with non-ferrous molten metals like aluminium
• Thermal & Electrical Insulation: Excellent dielectric strength and thermal reflectivity
• Easy Application: Available in brushable or sprayable consistency

Specifications:

• Appearance: Green paint
• Continuous Use Temperature: Up to 1260°C
• Layer Thickness: Approx. 0.25 mm
• Coverage: 1–2 m² per litre
• Dielectric Strength: 1535 volts/mm
• Thermal Conductivity:
  • 0.34 W/mK at 200°C
  • 0.41 W/mK at 400°C
  • 0.50 W/mK at 600°C
  • 0.57 W/mK at 1000°C
• Shelf Life: >1 year (sealed)

Common Applications:

• Furnace and boiler wall protection
• Bonding boiler and refractory insulation materials
• Molten metal containment areas
• Flame-exposed surfaces requiring enhanced durability

Supplied in 4-litre pails, QF180 is trusted for performance where standard coatings fail. For technical support or application guidance, view our full boiler & steam product range.
