MOPAR MUSCLE MAGAZINE

Take note that the August issue has a story on the build up of a 440. Our coatings are mentioned and a very good point is made. Under a photo of coated valves it says;

"Tech Line's thermal barrier coating was applied to the chamber side of the valves. We've found the coating here is a benefit in DECREASING the octane requirement, helping reduce heat transfer to the mixture, especially from the exhaust valve."

Their experience confirms the ability to help reduce detonation when applied to combustion chamber surfaces. This is a continuing story and they have mentioned the coatings before.

Report on Findings - TLHB Ceramic Coating

Vipro has experienced problems with the life expectancy of conventional coils springs, used as tension elements in a cone crusher application. The average life was around 3 - 4 weeks in the uncoated version and caused major downtime and related costs in getting these units replaced.

We stumbled across the TLHB Ceramic Coating, applied by Sartor Bros, who explained the properties and advantages of the coating to us. We decided to coat a sample of coil springs for installation on the West Coast, close to the sea, in very corrosive and unfriendly conditions. It was a desperate move, as nothing we tried before, worked with significant results.

After installing the sample coated springs, we have increased the life to more than 12 months at this stage, and it is still running.

We can highly recommend this coating for similar corrosion conditions, especially when you consider the relatively low cost involved to achieve this result, which is nothing compared to the cost of downtime.

We can be contacted for any references, if required.

Working Title: Powerkote Coats Polo Components for Engen VW Cup

Johannesburg - June 2005 - Powerkote has successfully applied its high temperature microfilm ceramic coatings to the exhaust manifolds of the 35 cars participating in the Engen VW Cup, part of the national SA Championship Power Tour.

The racing cars were experiencing several heat related problems during the race. Ian Pepper, a driver in the series, commented, "Our vehicles were excessively hot under the bonnet. The oil was running thin; the brake fluid tended to boil during the race, and the clutch fluid disappeared."

"We approached Powerkote to assist us to find a solution to these overheating problems, as well as to reduce the high temperature in the passenger compartments."

Powerkote applied its high temperature thermal barrier coating to all the exhaust manifolds of the 35 vehicles, which not only corrosion-protected the parts, but retained the heat within the manifold or header. This resulted in performance benefits as the exhaust gas velocity was accelerated, which reduced both back pressure and fuel contamination due to reversion.

The surface temperature of the manifold was also reduced substantially, which resulted in minimising the overall heat generated to the passenger compartment, as well as surrounding parts, such as alternators and starters. A secondary benefit was the reduction of heat drawn in through the carburettor.

Pepper added, "The ceramic coating reduced the heat up to 50%, which allowed the vehicles to run more consistently at optimum temperatures, which improved our overall performance."

The Engen VW Cup, which has been running for 9 years, is a popular series as all vehicles have identical specifications which keeps the development costs affordable, and ensures that the playing fields are level, so that the focus is on the drivers' skills.

Powerkote Cape recently sponsored Powerflow's VW Polo by coating the exhaust manifold, pistons and intake manifold for the race in the regional GTi challenge in the Western Cape.

Vehicle owner, Dick Bate, said, "The coating decreased the operating temperature of the engine, particularly the intake manifold, resulting in colder air and more consistent power, which is critical for racing conditions.

COATED BEARINGS

Differences between PTFE based coatings with a functional build up and DFL-1.

We are often asked what the difference is between a PTFE coated bearing and one coated with our DFL-1. Typically a PTFE coated bearing uses a binder that has a functional build up. This changes the clearances. While the coating is very durable and works well, once the coating begins to wear the clearances begin to get wider.

DFL-1 on the other hand uses a binder that is designed to quickly burnish, which may be accomplished by hand with Scotchbright or a similar material. When you assemble the bearings the clearances will only be minimally changed. When the coating burnishes further during operation, there is no significant change in the clearances. However the full function of the coating is still present as the lubricants will function in a film as fine as 20 millionths of an inch.
