SilcoTek® high temperature coatings reduce carbon fouling and catalytic interaction with the underlying surface. SilcoTek's CVD silicon coatings like SilcoKlean® or Dursan® bond to the surface and change the surface energy and inertness, preventing chemical adhesion and adsorption of the substrate and improving fouling resistance. The coating's low energy surface prevents the attachment of flow path chemicals to the surface.
The benefits of an inert anti-coking and fouling resistant barrier coating include:

Modern fuels can decompose and foul under extreme heat. With the advent of direct injection exposure to combustion conditions result in increased carbon fouling, poor fuel spray and inefficient flame propagation during combustion. SilcoTek® coatings reduce carbon buildup on fuel delivery flow paths, lubrication flow paths, and exhaust aftercoolers, preventing fuel injector fouling and improving combustion efficiency and maintaining peak engine performance. Applications include:
SilcoTek® coatings reduce carbon buildup on critical injection and fuel delivery flow paths, preventing fuel injector fouling and improving combustion efficiency and maintaining peak engine performance.

Turbochargers and exhaust intercoolers are exposed to extreme heat and exhaust particulates which can cause lubrication failures and exhaust EGR intercooler fouling. SilcoTek coatings reduce carbon fouling by preventing carbon formation and bonding to stainless steel and alloy surfaces. SilcoTek coatings prevent accumulation of carbon even under extreme combustion conditions found in IC engine pistons.
