Currently, anyone carefully observing modern professional racing cars will certainly see the many similarities from aerospace technology. The sharp, aviation tuned eye, will see a fascinating use of aerodynamics generating “lots of down force” with a minimum of drag coefficient, various types of composites for strength vs. reduces weight and hi-tech data acquisition equipment equal to any “Fortune 500” company’s research department.

A common problem with aircraft and racecars alike is heat management, or the ability to reduce engine compartment ambient temperatures. Some categories of racecars can generate EGT (Exhaust Gas Temperature) in excess of 1700° F! It is not uncommon to see racecars or aircraft fail because of electronic components being “heat soaked” to the point of breakdown. Given these quite similar situations, every method of reducing engine compartment temperature directly relates to a safer environment for all components, accessories and occupants.

HPC has revolutionized the exhaust component industry with highly developed coating technology. Testimonial to this achievement is 16 Daytona 500 and 15 Indianapolis 500 wins during our 19-year history. With such a rich racing heritage and the many performance improvements that have become so well accepted, you will find HPC products on OEM applications worldwide. Some aerospace manufacturers are currently increasing performance and component life in their products with a variety of HPC coating applications.

This strong foundation and over 19 years of coating technology development positions HPC as a pioneering leader in this field. From that experience comes a variety of coatings offering sport aviation the  same benefits provided national defense contractors, automotive and marine OEM’s and professional racing teams worldwide.

HPC currently manufactures and applies coatings specifically engineered for a wide variety of environments. HPC’s line of coatings include those that protect against corrosion, thermal fatigue and oxidation, some can reduce heat radiance more than 50 % and others are designed to reduce coefficients of friction. HPC coatings have found their way to the experimental aircraft brotherhood as a result of racing team members who use their products on racecars and realize those benefits can be gained with their aircraft.

The ability to reduce engine compartment temperatures, reduction of “heat soak” to neighboring accessories, increases in component life, performance gains and a clean appearance are all benefits of HPC exhaust systems coatings. The HCoat exhaust component coating has become the backbone of HPC’s family of coatings.

HPC HCoat coatings for exhaust applications come in a variety of colors, the most popular being HCoat Silver, a polished aluminum finish. Semi-gloss black, blue, red and gray are also available. These unique coatings not only maintain their finish, they also can reduce radiant temperatures in some applications by as much as 50%. HPC has determined that by coating the exhaust component inside and out a slight performance gain can also be found. Simple physics dictate that when heat is retained inside a diameter, gas velocity is increased, thereby improving combustion chamber scavenging and enhancing combustion chamber stability.

HPC HCoat provides protection from -350° F to +1300° F. Unlike electroplating processes, HPC lacks any potential for generating hydrogen embrittlement. HCoat bonds chemically and metallurgically at 10,000 PSI to withstand abrasion and sharp impacts!

HCoat (Polished Aluminum) will not oxidize, discolor or stain like chrome or polished stainless. HCoat has outstanding thermal shock resistance. When heated to over 1200° F and subjected to water quenching. HCoat is unaffected by the rapid temperature change. This coating is applicable to both new and used components. It is recommended that heat muffler shielding be removed and muffler location be identified prior to having any exhaust system coated. Mufflers are NEVER COATED in order to provide maximum efficiency for carburetor and cabin hot air exchange.

HiPerCoat meets U.S. military specification MIL-C-81751B for metallic ceramic coatings.

HCoat Extreme is the answer for applications where exhaust component temperatures exceed 1300° F for continuous periods.  HCoat Extreme is functional at temperatures exceeding 2000° F and certified testing has shown a component skin temperature drop of over 50%! HCoat Extreme is applicable to new or used components is available only in black, gray or blue.

Another performance application with growing popularity is HPC S-Series Solid Dry Film coatings (SDF) inside valve covers and other internal engine surfaces in contact with oil and condensate liquids. This coating application eliminates corrosion and scaling build up on internal surfaces, allowing the lubricants to free-flow to filters, carrying the harmful particulates otherwise collected on those surfaces. This coating can also be applied to new and used components.

International in scope, HPC has seven facilities worldwide. With three facilities in the USA and four overseas operations, HPC stands at the ready to offer the highest quality coatings for every application, large or small. A highly skilled and knowledgeable technical staff is available to assist with the proper duty application for any HPC product.
