New Product LAUNCH – Primary Gunmetal Grey™

We’re delighted to launch our brand-new heat management ceramic coating finish – Primary Gunmetal Grey™.


Primary Gunmetal Grey™ has been specifically developed as an affordable all-rounder, perfect for reducing the surface temperatures of exhaust systems. Balancing thermal performance with affordability, this ceramic coating will appeal to users who want some of the benefits of Zircotec’s plasma sprayed thermal barrier coatings, but who might not need the ultra-high levels of thermal barrier performance available by Zircotec. By popular demand, we can now offer a stunning gunmetal grey finish that compliments any engine bay style/setup, whilst of course offering the renowned levels of heat protection Zircotec has become known for.

Our Primary Range™ of thermal barrier ceramic coatings offers up to 25% surface temperature reductions, with a max operating temperature of 900°C .

All our coating finishes are put through their paces, with OEM level testing to ensure their durability and performance. Primary Gunmetal Grey™ holds the same bonding, porosity, and coating system parameters as our established Primary Black™ coating. In addition to thermal barrier properties, our Primary range of coatings offer corrosion resistance, chemical stability and adherence resistance.

Primary Gunmetal Grey™ offers an entry-level coating solution for customers who are looking to protect their vehicles from heat damage, as well as improve the aesthetics of their engine bay. This coating is perfect for daily drives, show cars, classic cars etc. If you’re looking for higher-performance coatings that can reduce surface temperatures and improve performance even further, be sure to check out our Performance Colours™ or Performance White™ coating options.

Primary Gun Metal Grey™ is a ThermoHold® based ceramic coating, which is only available from Zircotec. We have been the trusted supplier of heat management ceramic coatings for Motorsport teams and Automotive OEMs for the last 25 years.

Primary Gun Metal Grey™ can improve your car/bike performance by:

  • Reducing Heat Transfer – Proven to reduce exhaust surface temperatures by up to 25%.
  • Aids the reduction of inlet charge and fluid system temperatures, whilst increasing driver comfort.
  • Retention of heat / energy in the exhaust gas stream, thus improving gas speeds and providing a positive effect on power and torque.
  • Rapidly cooling the exhaust when the engine is turned off.

It is only 0.3mm thick, therefore adding minimal weight onto vehicles. It is suitable for applications for up to 900°C (1,650°F) and we would recommend uses on:

  • Exhaust Manifolds
  • Turbo Housing
  • Downpipes
  • Tailpipes
  • Silencers
