More information on ARD's Ceramic Coatings
The coatings ARD offers are capable of withstanding temperatures of 2000F. In addition they offer excellent chemical and corrosion resistance and possesses excellent thermal barrier characteristics, providing a dramatic reduction in radiated heat. This means reduced under-hood temperatures, accelerated exhaust gas velocity and a longer life expectancy for the downpipes.

Ceramics stand above all other thermal barrier coatings currently being used in combustion chambers. Ceramics have characteristics shared by no other product, providing an unrivaled layer of thermal protection to piston tops, aluminum heads, stainless, iconel and titanium valves. Ceramics "move" heat, reducing detonation and increasing the effective oxidation of fuel. When polished, it provides a highly reflective surface that further aids in improved flame travel. Unlike previous ceramic coatings, ARD's coating is not subject to cracking and flaking, which can lead to extensive engine damage. In fact, Ceramic coatings actually strengthen the coated part. The cured "Cermet" provides a cap of material that can withstand far more heat. During testing when sufficient heat was applied to a piston to melt the aluminum, the Ceramic did not melt, rather it held the softer aluminum together.

The Satin Ceramic Exhaust Coatings ARD offers are the most advanced exhaust system coatings available. They are a very durable ceramic-reinforced coating available in various shades. When properly applied, it becomes the most effective thermal barrier coating available, increasing performance while extending component life, and has been tested to over 2000F without lifting, cracking or flaking.

2000F coatings are available in the following colors:

- Satin Grey Ice
- Satin Titanium
- Satin Blue
- Satin Fresh Blast
- Satin Dark Blue
- Satin Grey
- Satin Black

Please add 2-3 weeks to delivery time for coated downpipes, or call to see if we have your choice of color available in stock.
