Properties Enquiry

ZircoatZircoat is a unique refractory coating compound, which is a great benefit to the industries where corrosion and erosion is a severe problem for refractories and kiln steel shells. It seals cracks, preventing heat loss, and therefore saves heat energy and reduces fuel costs increasing considerably the service life of refractory linings and thermal heating systems.

Zircoat is a new specially formulated refractory ceramic coating cement rich in Zircon, and is particularly effective for uses in industries where high temperature resistance is essential. It has been tested to continue to provide protection from slag adhesion as well as chemical resistance and continued strong adhesion up to temperatures of 1500oC and 1800oC depending upon the grade of Zircoat that you choose, making it ideal for uses in combustion chambers, kilns and furnaces.

NB - Minimum order quantities apply.


Zircoat HT. This coating is meant only for refactories used in furnaces and kilns and withstands temperatures up to 1800oC.

Zircoat M. This coating is used in furnaces and kilns as well as on metals, withstands temperatures up to 1500oC.


  • Reduces slag adhesion
  • Seals cracks preventing heat loss, considerably saving heat energy and reducing fuel cost

Simple preparation, can be applied by trowel, brush or spray. Mix powder with water to form paste, and add water (depending upon required consistency for method of application). Leave to air dry for 24 hours then slowly raise the temperature to 1200oC (increasing by 25oC per hour), and rise to operating temperature (increasing by 50oC per hour).
