It is labeled as a "PTFE Grease".
PTFE is Polytetrafluroethylene and microparticles of PTFE are suspended in Magnalube®-G to ensure continued performance of equipment operating at high loads and extreme temperatures. That simply means that although the grease is made to operate in temperatures from -35 degrees to as high as 458 degrees, if the petroleum base of the grease should burn up, the PTFE remains on the equipment to continue to serve as a lubricant.
This product has been a specialty lubricant for over 30 years, but was just recently discovered as a great firearms lubricant. They asked me to evaluate the product and do an evaluation of the application on firearms.
Many years ago, I sent a Browning HiPower to Cylinder and Slide for a trigger job. They did a fine trigger job on my pistol and included a piece of literature that described the advantages of using a grease on firearms, especially semi-auto pistols. The main issue was that although a good quality oil will lubricate just fine, if you lay the pistol down or carry it in a holster, the oil will tend to drain from the area where it was applied and leave important areas without enough lubrication.
In contrast, a high quality grease will stay right where you put it and will not drain away from critical areas. I have been putting grease on the slides and rails of my semi-auto pistols for many years, with very satisfactory results. |
