Despite being able to withstand temperatures up to 440° Fahrenheit, nano ceramic coatings are not going to offer much on the heat shielding side of things. Unlike nano-ceramic coatings, which are completely transparent, the high-temperature material can be purchased in a multitude of colours and paint finishes. This does not make one form of ceramic coating better than the other, but gives each its own strengths and weaknesses. With a plethora of colour and gloss options available, the appeal associated with high-temperature tile sprays goes far beyond thermal control and protection.
To protect these expensive parts, engine enthusiasts opt for professional powder coating or high-temperature ceramic spray coating. Everyone from aftermarket enthusiasts in their garage with cans of spray paint in hand, to manufacturers of robotically applied OEM coatings, to racing teams looking to keep temperatures under control have been swearing by this material for decades. We will also look at the differences between high-temperature ceramic sprays and nano-ceramic coatings, because although both products are designed to protect a hard surface, they are very different in many ways. Applying a high-temperature ceramic coating to both the outside and inside of an exhaust system helps to improve the flow.
Since it is usually slightly more expensive than low-temperature ceramic coating spray, the mid-grade material strikes a good balance between affordability and high-temperature functionality. The harder forms of ceramic coating heat protection are designed specifically for racing and interior engine applications. Although certain high-temperature ceramic products have a silicon ceramic matrix, and serve many of the same purposes as a DIY nano-ceramic coating, that is where the similarities between the two end. The main reason most people opt for a ceramic coating on their car and motorbike parts is to protect them from the elements and keep heat under control, which in turn helps prevent the inevitable onslaught of corrosion and rust.
While both products are designed to protect the surface from contaminants and physical damage, most nano-ceramic coatings cannot withstand extreme temperatures for long periods of time. Just as the heat resistance of the ceramic coating protects the head itself, it also restricts heat emissions and reduces the temperature under the bonnet. For the turbocharger and supercharger components, the application of a high-temperature ceramic coating helps to maintain lower surface and internal temperatures and therefore reduces the risk of engine overheating problems. Nano-ceramic coatings are also ideal for brake calipers, valve covers, catch and overflow reservoirs and engine covers.
