Super thin micro coating at 100 - 200 nanometers thick. Repels water and oil but is vapor permeable. Corrosion resistance and low coefficient of friction. Does not transmigrate or cross-contaminate. Good dry lubricity with an operating range of between -50 degrees to 450 degrees Celcius. Blocks off more than 95% of UV. This chemically non-reactive does not bond with other substances. A single application can last thousands of production cycles.
