A coating formulation for application to surfaces associated with combustion, such asnfuel injectors, and surfaces subjected to elevated temperatures, such as fuel supply components,nto prevent the deposition at high temperatures of carbon or graphite on such surfaces, such asnstainless steel and alloyed steel compositions. The coating formulation forms a thin layer ofnpolymer coating on the surface by chemical grafting involving the use of a graft initiator toncreate active bonding sites, on the metal surface, for the silicone-based prepolymer to undergonpolymerization on the metal surface. The bonding and polymerization are completed in a singlenapplication process without using complex equipment. The coating and process helps surfacesnassociated with combustion and surfaces subjected to elevated temperature reduce carbon orncoke formation at temperatures up to 700°F and thereby improves the durability andnperformance of those surfaces. |
