Zircotec exhaust coating reduces Aston Martin’s temperature under the hood

Zircotec’s ceramic coating technology is used to reduce the surface heat of exhausts, and Aston Martin saw the potential in the material for cooling its V12 Zagato endurance racing car at the Nürburgring 24 Hours. The coating, derived from Zircotec’s ThermoHold, was selected by the manufacturer for its durable and lightweight method of reducing under-bonnet temperatures at the Nordschleife, improving reliability and preventing heat damage to bodywork, fuel and electrical systems. With its origins in the nuclear industry, Zircotec’s ThermoHold technology is applied to the exhaust system by plasma spraying to prevent heat being radiated by the 6.0 litre V12 engine.

Keeping heat inside the exhaust also lowers cockpit temperatures, improving driver comfort and safety. The company says that a growing number of classic Aston Martin owners are also benefitting from using the Zircotec coating, which is now available from the manufacturer’s Works Service department.

“Zircotec’s coatings are an attractive alternative for classic and performance car owners looking to enhance durability, performance and comfort,” says Peter Whyman, sales director at Zircotec. “In addition, the textured finish and range of colours ensure it is aesthetically more appealing than legacy technologies such as wrap. And unlike wrap, it is fit and forget too, meaning no maintenance is required for a 24 Hour race and years to come after.

“Driver comfort is crucial at long distance events such as these,” adds Whyman. “The significant speed differences, long lap and often challenging weather conditions at the Nürburgring means anything that helps to improve the environment and their focus is a worthwhile addition to the specification.”
