HP1 Pol Alum

Heavily reduced under bonnet temperatures improve engine performance and longevity, reduce fuel use and a fantastic appearance are all attributable to HPC’s HP1 exhaust coating.

That’s right in recent years, HPC’s HP1 coatings have revolutionised the header/extractor industry to the point where anyone serious about performance invariably coats their headers. 

So how does a seemingly simple coating achieve all of this?

The unique HPC’s HP1 process is designed to protect steel against corrosion and thermal fatigue/oxidisation created by cyclical temperatures.  Performance is enhanced by reducing under bonnet temperatures, improved air density assists combustion chamber stabilisation, and increased gas velocity is achieve by the coating’s heat retention properties.

Applied to the inside and outside of a header HPC’s HP1 exhaust coating eliminates oxide scale, with improved laminar air flow a direct result.  Improved performance directly relates to enhance fuel consumption, header life typically increases five fold, while the finely polished exterior adds a lustre otherwise unobtainable in an exhaust system.

Reducing under bonnet and undercarriage temperatures can significantly reduce heat soak in carburettors, fuel lines, master cylinders, accelerator and clutch cables as well as a myriad of other components, hence reduce component degration for longer life and more reliable running.

Understand that these are not merely claims, rather HPC researches, manufactures and certifies it’s coatings to meet specific requirements.  HPC’s HP1 offers protection at temperatures of -190c to + 700c.

HP2 Satin Black

HPC’s HP2 Satin Black exhaust coating has all the benefits of HPC’s Pol Alum exhaust coating and more.

This coating is a five coat system with two base coats and three Nano top coats.  HP2 Satin Black has proven to be highly effective in prevention of heat scaling, oxidation, erosion/abrasion and saline corrosion. Corrosion and thermal fatigue which occur as a result of exposure to cyclical temperatures and chemical environments, can be drastically reduced.

HP2 Satin Black offers protection to you exhaust at temperatures of – 170c to + 800c , so you can expect even greater heat reductions.

HP3 Cast Iron Grey

HPC’s HP3 Cast Iron Grey exhaust coating has all the benefits of HPC’s Pol Alum exhaust coating and more.

This coating is a five coat system with two base coats and three Nano top coats.  HP3 Cast Iron Grey has proven to be highly effective in prevention of heat scaling, oxidation, erosion/abrasion and saline corrosion. Corrosion and thermal fatigue which occur as a result of exposure to cyclical temperatures and chemical environments, can be drastically reduced.

HP3 Cast Iron Grey offers protection to you exhaust at temperatures of – 170c to +800c , so you can expect even greater heat reduction.

TC1 Turbo Coat Extreme

A significant step up in it’s temperature handling capabilities is HPC’s TC1 coating.  Specifically designed for applications such as turbochargers where substrate temperatures can exceed 1300 degrees Celsius, in black only the coating helps maintain exhaust gas temperatures, increase flow velocity, aid cylinder scavenging and assist in preventing damage to hoses, belts and wiring harnesses. Indeed, it’s the experience of almost every V8 Supercar racer in the country, and race car owners in all areas of motorsport the world over, that has them coating exhaust systems.

Track testing has shown as much as a 30% reduction in under bonnet ambient temperatures and up to a 50% reduction in component skin temperature.  HPC’s TC1 achieves this by creating a thermal barrier that retains heat, which in turbo charge applications assists to increase turbo boost and spool-up.  Which is why today’s leading CART, NASCAR, IMSA, V8 SUPERCAR and F-1 Teams use HPC’s TC1 process.

TBC1 (Thermal Barrier Coatings)

Pistons, Valves, Combustion Chambers and Port Runner Coatings

Combustion chambers and exhaust port runners benefit greatly form TC1, in particular aluminium heads with significant reduction in heat soak resulting in lower water temperature and by retaining heat in the combustion chamber fuel burn is improved.

Valves undertake extreme thermal shock.  Considerable research shows that an application of TBC1 to the combustion face of the valve prevents the exhaust valve overheating an intake tract heat transfer.  The upshot is a denser air/fuel charge.

What one part suffers greater duress and thermal shock than almost every other engine part combined? The piston.  That’s why we developed two distinctly different coatings to protect both the crown and skirts from wear and damage.

We apply an incredible durable Thermal Barrier Coating (TBC1) to the combustion face of the piston, and a wettable (DF1) to the skirt.  The process involves bonding particulates with an inorganic binder that is completely unaffected by petroleum products.  With a bond strength of 10,000 psi, the coating’s non-porous ceramic matrix results in improved flame travel and combustion efficiency, oil temperature is reduced and it prevents carbon buildup.

HPC’s TBC1 prevents excessive heat from reaching the piston rings which results in less radial tension loss, less compression loss and less oil consumption due to the rings overheating.  TBC1 prevents heat losses through the piston and cylinder temperatures are maintained.  Because of this more horsepower is achieved due to increased fuel burn.


DF1 (Dry Film 1)

Wettable Matrix Applications to Pistons and Springs

We also protect the piston skirts via a Molybdenum Disulfide DF1 coating designed to attract oil to ensure the piston skirt always maintains an adequate film of oil for reduced friction and scuffing.

Motorcycles, sprint cars, vintage cars, race cars, Indy cars, trucks and compressors; it really doesn’t matter what the application, a coated piston delivers improved performance.

Go-fast, low friction Engine Coatings act like a sponge, soaking up oil to lubricate and reduce friction.  It helps to eliminate fretting, galling and seizures and withstands fuel additives and nitromethane.

A valve spring’s biggest enemy is heat generated from compression and extension cycling, friction between the coils on double and triple springs or the spring and dampener and through absorption from the cylinder head; especially the exhaust spring being right over the exhaust port.  A valve spring’s only cooling is achieved from oil splashed over it by the rocker arms.

HPC’s DF1 Solid Dry Film Lubricant coating solves the heat problems through superior high pressure lubrication qualities and the ability to attract oil like a magnet.  Valve springs coated in DF1 can retain the seat pressure up to three times longer than uncoated valve springs.

DF1 Applications:

  • Piston Skirts
  • Carby Slides
  • Springs
  • Oil Pump Gears

DF2 (Dry Film 2)

Non Wettable Matrix Application

Keeping oil where it belongs is the job of our non-wettable oil shedding DF2 coatings.

HPC’s family of non wettable coatings is perfect in areas with little or no liquid lubricants.  This process works well in eliminating exfoliation/corrosion and oxidation on zinc, aluminum and magnesium, and can be applied directly over more conventional pre-treatments such as anodising, phosphating and electroplating.  The attractive satin finish shed oil like water off a duck’s back, promoting oil return and reducing windage.

DF2 Applications

  • Inside Oil Pans
  • Windage Trays
  • Connecting Rods
  • Inside Valve Covers

DF3 High Build Coating (Dry Film 3)

HPC’s DF3 Proprietary high build piston and blower rotor coating was developed for world Top fuel drag racing champion Eddy Hills blower rotors.

This inorganic single-bonded dry film contains a matrix selected to increase the lubricity and load-bearing capability when subject to high pressure and mid-range temperatures.  It provides excellent wear properties while reducing friction loads.  

HPC’s DF3 coating is a High speed Teflon which reduces friction and can be built up to .003” on piston skirts or rotors.

DF3 Applications

  • Piston Skirts
  • Blower Rotors

DF4 (Dry Film 4)

DF4 Extreme release is designed with PTFE, these applications provide outstanding chemical corrosion protection on ferrous and non-ferrous materials.  Dissimilar metal corrosion between tightly compressed components will be greatly reduced after being treated with DF4.  Its non-wettable properties allow solutions to glide across the substrates rather than being absorbed and attack the substrate.

DF4 Extreme release coating is ideal for plastic rotational moulds to release plastic components from the mould without using release sprays.
