SpecHeat Silicone 540 Aluminium

Temperature Resistant. A single component, heat resistant, aluminium pigmented silicone resin based temperature resistant coating.


A heat resistant topcoat for high temperature service. It is used for the internal and external protection of steel surfaces. Temperature resistance is up to 540°C. When used over Inorganic Zinc Primer will provided excellent corrosion protection in humid environments and protection from corrosion due to condensation but maximum temperature is subsequently reduced to 420°C.

Recommended for stacks, furnaces, boilers, jet engines and metal parts which operate at elevated temperatures.

Used for new fabrication/construction and maintenance.


  • Heat resistant to 540°C.
  • Overcoatable, no restrictions long term
  • Suitable as a topcoat over inorganic zinc primer for steel structures in plants operating at elevated temperatures, the combination offers excellent corrosion protection
  • Bright, leafing aluminium finish
  • Effective corrosion protection at elevated temperatures
