Moly Resin™ was specifically designed for firearm owners. A product that can easily be applied in your shop or at home.


Discover Moly Resin

Moly Resin/Norrell’s Moly Resin™ is a product trademark of John Norrell Inc. Moly Resin™ is a thermally cured phenolic coating initially developed for aluminum AR-15/M-16 receivers and stainless steel sound suppressors. Today, Moly Resin™ is used on all metals throughout the firearms industry by gun shops, firearm parts manufacturers, start-up manufacturers, gunsmith schools, home DIYers, and law enforcement agencies for ordnance usage on equipment and weapons. The low temperature activated catalyst hardens and bonds the coating to all metals to create a hard, durable, chemical and a heat resistant state-of-the-art firearm finish. Our goal is to provide an array of popular colors that match closely to those being currently used in the firearms industry and military, as well as, vintage colors for special firearm restoration projects. The application process is relatively simple and is based on the use of an inexpensive air brush followed by curing in an oven.


The bonded coating will appear uniform in color, smooth a
nd free from cracks, runs, sags, scratches, pin holes, blisters, bubbles, and foreign matter.


The optimal thickness of the coating will be between .0003″ and .0009″ unless a thicker coating is desired. The thin coating characteristics of less than one thousands of an inch allows easy re-assembly of precision fitted parts


Moly Resin™ contains molybdenum disulfide, which provides excellent anti-friction characteristics. Wear life is comparable to blued, parkerized and other common firearm finishes. Moly Resin™ is a phenolic Resin that when thermally cured, produces the most durable thermally cured painted surface of any products on the market. Wear life when tested on Tabor Abrasurf with #CS10 wheel installed @ 500 grams weight minimum 235 RPM’s.

Thermal Stability

The cured coating will withstand exposure at 500 F for 1000 hours minimum and 1000 hour minimum soak at -125 F. Minimum initial oxidation temperature is 880 F. Thermal breakaway is 1000 F minimum.

Fluid Resistance

Moly Resin™ will meet 24 hour emersion requirements in the following fluids: aviation gasoline, hydraulic fluid, jet fuel, lubricating oils, paint removers, trichlorethylene, nitric, sulphuric and hydrochloric acids, hydrogen peroxide, gun powder solvents, strong bases such as ammonium and sodium hydroxide, and numerous other strong chemicals.

Corrosion Resistance

Moly Resin™, when applied to bare sandblasted cold rolled steel will pass the test procedures for salt water spray at 1000 hours, salt water immersion at a minimum of 1000 hours, accelerated salt spray test equivalent to 30 years marine atmosphere exposure, and 60 days sea water immersion.


Hardness meets and/or exceeds the hardness of any Epoxy,Teflon or most other thermally cured firearm coating or paints on the market. hardness for thermal cured Moly resin exceed a 9H on the paint hardness scale.

Shelf Life

Moly Resin is a thermally cured coating, therefore, it is temperature sensitive. Storage should be in a cool area that is out of the sun. Under normal conditions, expect shelf-life of one year or longer. If you are able to store the product in a refrigerator, the life is extended significantly.
I am so impressed that I put the gun out on display. It should be a big draw. It is true what they say about you. You’re the best!

The finish is the strongest and easiest to apply I have ever seen. You can tell that it is hard and has very low friction properties.  The coating looks exactly like my original Parkerized finish.
