Technical Data

Material Compatibility Application:
Mild Steel, Stainless Steel, Cast Iron, Aluminium Alloys

Description: JET-HOT Colours are applied over JET-HOT Silver Base Coating this gives it all the same features and qualities as JET-HOT Hi-Lustre. Corrosion Resistance as tested in Accelerated Salt Spray tests have proven that JET-HOT last over 5 times longer than other Metallic Ceramics, more than 14 times longer than Chrome, and over 140 times longer than high-temp paints. High-Temp Fatigue Resistance test have shown after 10-million stress cycles over 300 hours at 1000F, that uncoated 403 stainless steel had a fatigue strength of 56,000 psi and JET-HOT coated 403 stainless steel was 68,000 psi.
This coating when applied to exhaust headers or manifolds acts like a thermal barrier and keeps the heat in side the headers, reducing under bonnet temperatures. Another unique feature is JET-HOT’s ‘self-repair’ quality, the coating continues to provide protection even when scribed to the base metal by ‘sacrificing’ itself to the substrate. Because the coating is electrochemically active, you can obtain OHM readings. Dissimilar metals generate an electrical current. In this case, one metal behaves as an anode and the other as a cathode, like a battery. The anode reacts with the media, or environment it is exposed to, and it’s self scarifies, creating a soluble chemical compound that keeps forming and provides galvanic protection.

Mild Steel, Stainless Steel, Cast Iron, Aluminium Alloys

Description: JET-HOT TDC has the same features and Qualities as JET-HOT Hi-Lustre. Corrosion Resistance as tested in Accelerated Salt Spray tests have proven that JET-HOT last over 5 times longer than other Metallic Ceramics, more than 14 times longer than Chrome, and over 140 times longer than high-temp paints.

When this coating is applied to oil pan, gearbox housings help to dissipates heat more effectively than any other coating, it dissipates heat 18% quicker than normal JET-HOT this is due to the higher surface profile which reacts with the air flow passing over it. Another unique feature is JET-HOT’s ‘self-repair’ quality, the coating continues to provide protection even when scribed to the base metal by ‘sacrificing’ itself to the substrate.

Description: JET-HOT 2000 has Black or Cast Iron Grey Colour and a satin semi smooth appearance. JET-HOT 2000 is from the Metallic Ceramic family of coatings. Corrosion Resistance is extremely high and provides protection at temperatures up to and above 2000f(1100c). This coating when applied to exhaust headers or manifolds acts like a thermal barrier and keeps the heat in side the headers, reducing under bonnet temperatures. It particularly good for turbo manifolds and housings were the temperatures are extreme.
JET-HOT 2000 is not effected by Petrol, Brake fluid, Oils or Antifreeze. The coating provide protection against Rust or Oxidization of metal surfaces from normal to extreme temperature environments up to 2000f (1100c). High Alkaline compounds will dissolve the coating.
Note: JET-HOT 2000 was tested at 2000f (1100c) but it has been found to stand temperature in excess of that. It is capable of with standing temperatures too almost 1300c.

Technical Data

Material Compatibility:
Mild Steel, Stainless Steel, Cast Iron, Aluminium Alloys

Description: JET-HOT TBC (Thermal Barrier Coating) applied to the top of pistons will increase combustion temperature, because of the ceramic nature of the coating, it acts like a thermal barrier, reducing the amount of heat lost into the piston. This gives a higher compression temperature producing more power and better fuel efficiency. Reducing the temperature to the top of the piston will allow cooler running pistons, rings, and water, maintaining ring tension leading to higher compression and lower oil consumption over a wider operating rang.

Coating Effects on Temperature.

When JET-HOT TBC is applied to the top of a piston, valves and combustion chamber, it helps to even out the temperature and reduce the detrimental effects of hot spots. The heat transferred to the lower parts of the piston is reduced allowing the piston to run cooler, this also helps to reduce the oil and water temperature. When the air/fuel mix enters the cylinder it expands due to the heat radiated from the combustion chamber and cylinder walls. This expansion slows the velocity of the entering air/fuel mix. Because the coating doesn't radiate heat well it reduces the amount of heat transferred to the incoming mixture, thus filling the cylinder with a higher concentration of air and fuel.

Other Information.

Above: A typical piston heat range during combustion for a petrol engine. Typical cylinder compressed temp. is 2000C - 2500C

Piston Information

Piston alloys contain Silicone. Some Manufacturers increase the silicone content of pistons making them harder, improving strength and wear properties. All pistons are heat treated to improve their strength and "Straight Age"(Note: (a)) them before Machining. A piston in a go kart and other race engines may have a higher silicone content than a piston in an average automobile. This is done because the engine of a go kart revs much higher and is under greater stress.

Piston Failure

One of the major causes of piston failure is detonation. When a ceramic coating is applied to a piston top and a combustion chamber, it will increase the heat retained by combustion and this in turn may cause bad detonation. There should be an adjustment made to engine tune to compensate.
JET-HOT Valve Information When JET-HOT TBC coating is applied to the valve head it helps to even out the temperature and reduce the detrimental effects of hot spots. The heat transferred to the stem of the valve is reduced allowing the valve to run cooler. The JET-HOT LFC applied to the stem of the valve helps to retain oil and transfer the heat to the guide and cooling system reducing wear and allowing for more free operation thus reducing the chances of galling.
Note : (a) Straight Age heat treatment is done to pre-age casting. For example if a piston was not aged before it was machined it would change shape even before it is fitted to the engine not to mention what would happen after it reached high temperatures. The pure crystalline structure of metal is a regular matrix of straight lines and because of these straight line structures, it makes the metal quite weak, for example if pressure was exerted from opposite directions, it would cause this structure to slip and fail. The strength of this structure can be increased by introducing different molecules into it, forcing the regular matrix to become irregular. This is done by introducing silicone and other materials into the alloy. After casting, the piston is heated at a steady temperature for a set period, allowing the molecules to migrate throughout the part evenly, this is called aging. If the part is reheated to the aging temperature again or above, the molecules continue to migrate, they eventually find other molecules of the same nature and form large concentrations of this material, this is called over aging and this weakens the matrix.

JET-HOT LFC Technical Data

When JET-HOT Low Friction Coating (LFC) is applied to piston skirt, valve stems and other components it reduces the friction between moving parts in extreme conditions. JET-HOT LFC retains oil ensuring an oil film is always present, resulting in an increase in parts life through less friction. JET-HOT LFC even provides protection against friction when oil isn’t present, extending parts life. It has a load carrying capacity of 150,000 psi. and a coefficients of friction as low as 0.019 (dry), that's lower than steel on ice. Other components like camshaft, valve train parts, diff gears and gearbox parts can benefit from JET-HOT LFC.
