Diamond Black^TM - high performance exhaust system coatings

Technical Outline

Our Diamond Black^TM ceramic coating is designed to provide an attractive yet extremely tough and durable finish that is exceptionally hard wearing and highly resistant to stone chipping and other forms of mechanical damage. As a thermal barrier coating it is ideally suited for exposed areas of an exhaust system where aesthetics are important, and where physical damage might be a problem. It is particularly well suited to tailpipe sections.

In developing this coating we have aimed to maintain a high level of thermal barrier performance, though we have necessarily sacrificed some of the extremes of performance offered by our other thermal barrier coatings. We do not recommend this coating if uncoated exhaust surface temperatures are likely to exceed ~400^oC (~750^oF).

Our standard colour is black, though in some lighting conditions the coating may appear to have a very slight blue/grey appearance. It can be applied equally well to new or used systems, and to most metals & metal alloys.

This coating has passed our rigorous product testing and verification regime (read more). We are therefore happy to supply this coating with Zircotec's standard 3 year Product Guarantee.

We have the option to customise this coating to produce other variants within the range. For example, we are able to achieve various shades of dark grey through to a dark blue/grey (with further variants possible in terms of surface finish and texture). We do not currently supply these coatings as standard product, however we are happy to work with our business customers to meet specific performance or design requirements (see our Special Coatings page).
