Insulation Thermal Resistant
 RCF Free Mastic
IR also manufacture a health safe ceramic free mastic which can be used in most applications where Ceramic Fibre mastic is currently used.

Other benefits include:
    • Ceramic fibre free
    • Low thermal conductivity
    • Low heat storage
    • Reduces fume emission around refractory
    • Excellent thermal shock resistance
    • Resistance to gas velocity
    • Easy to install
    • Adheres to most ceramic and metallic surfaces
    • Excellent corrosion resistance
    • Inert to most chemicals
    • Impermeable to molten aluminum, zinc,
    • copper and lead
    • Contains no asbestos
    • Ready to use
    Used in:
    • Troughs or Liners for non-ferrous metal transfer
    • Gaskets and Seals around Burner Blocks
    • Protection of metallic parts from heat
    • Pump into voids in badly damaged back-up insulation
    • Gasket and Seals for Chimneys and Stacks
    • Boiler Door Seals and thermal insulation
    • Void and cracks Filling on refractory surfaces
