High Temperature Coatings

The corrosion protection of high heat areas associated with high temperatures is the perennial problem to the industry. Hir ThermoCoat range High Temperature Coatings protects the steel structural against atmospheric corrosion and under insulation corrosion up to 1000°C (1832°F). The coatings can even be sprayed to hot surface till 120°C (248°F). The excellent resistance to thermal shock as a result of rapid temperature cycling extends life expectancy of assets.



High Voltage Insulation Coatings

Hir's High Voltage Insulation Coating is especially formulated to enhance your utility reputation with dependable, cost-effective high voltage distribution systems. Build the efficient transmission and distribution systems needed to meet growing global demands for electrical power.

Pollution of outdoor high voltage insulators is a common problem for utilities, with a considerable impact to power system reliability. A possible outage in a high voltage system usually corresponds to a severe impact to the power system. In an effort to prevent possible flashovers due to pollution, high voltage insulation coatings have been designed, aiming to improve the insulation performance, either by suppressing the formation of surface conductivity or by increasing the possible insulation level, since the coating can be installed at a time convenient for the utility and within its operational lifetime is capable of suppressing the pollution influence at any time.

Hir's InsulCoat high build PolySiloxane RTV coating specially designed to give electrical insulators long-term resistance to water filming and high level of flashover resistance under conditions of high voltage corona stress, even after extended periods of exposure to ultraviolet light.



High voltage infrastructure can benefit from:

Superior arcing and ash over protection
Reduced leakage currents ensured by long-term hydrophobicity
Extended maintenance intervals for ceramic, porcelain, or glass insulators
Lower maintenance and replacement costs
Minimized equipment problems and failures
