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 HiPerCoat® exhaust component
coating has become the backbone of HPC's family of coatings.
HPC HiPerCoat coatings for exhaust applications
come in a variety of colors, the most popular being HiPerCoat 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 HiPerCoat provides protection from
-350° F to +1300° F. Unlike electroplating processes, HPC lacks any potential
for generating hydrogen embrittlement. HiPerCoat bonds chemically and
metallurgically at 10,000 PSI to withstand abrasion and sharp impacts!
HiPerCoat (Polished Aluminum) will not oxidize,
discolor or stain like chrome or polished stainless. HiPerCoat has outstanding
thermal shock resistance. When heated to over 1200° F and subjected to water
quenching. HiPerCoat 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.
HiPerCoat Extreme™ is the answer for
applications where exhaust component temperatures exceed 1300° F for continuous
periods. HiPerCoat Extreme is functional at temperatures exceeding 2000°
F and certified testing has shown a component skin temperature drop of over 50%!
HiPerCoat Extreme is applicable to new or used components is available only in
black, gray or blue.
