Brian with JCM provided the following information on how well our coating is protecting Engine Bearings.

OK, let me tell you a little story on how effective ceramics and dry film lubricants are in the internal combustion engine. We do a complete thermal and dry film management program for a guy who builds demolition derby engines. They are typically small block Chevys. We have gotten excellent feedback from him on how well these engines perform and last with the coatings. Typically, when an engine, in this type of environment, looses a radiator, it only has about 5-10 minutes before it locks up. One of our coated engines lasted 31 minutes after loosing it's radiator and reached internal temps of around 450 degrees. How do I know it was at that temp? Well, babbitted bearings melt at about 450 and metal starts to blue at 450. *After this car won the event, it was brought into the pits and shut down.** After the engine was off and there was no oil flowing to help cool the bearings, the heat from the camshaft actually started to melt the babbit out of the cam bearings which peddled down the oil galley to the main bearing, plugging it off.

Keep in mind, the car still ran fine. The driver, not knowing his engine had any damage went on to race two other events with no signs of any internal engine damage*. The engine was torn down to reveal what had taken place. The camshaft and crankshaft where blue but I didn't get any pictures of them, and they were polished and put back in the engine! Oh, the other two events he went to, won them both!

As a side note, the photos of a cam bearing and a main bearing from this engine are available.

Heavy Duty Truck Exhaust Coating

Pac Brake has just received approval from a major OEM manufacturer to substitute a new coating developed by Tech Line Coatings for a coating previously applied by another company. The Tech Line Material showed equal to superior heat insulating properties at a reduced coat with all other capabilities being comparable. The new coating is a “Thick Film Coating” (TFC™) material that is applied over Cast Iron components at approximately 15 thousandths and then top coated with a seal coat.
