Moly Resin Overview

Moly Resin™ is a product trademark of John Norrell Arms, Inc. d/b/a Norrell Manufacturing. These finishes are specifically formulated from a phenolic resin base and molybdenum disulfide (a superior lubricant) with an exclusive blend of additives only available through Norrell Manufacturing. Our additives create a phenolic coating that is hard, durable, and extremely chemical and heat resistant. Our special low temperature catalyst will cause the Resin to harden and bond to the surface to form a barrier to acids, oils, paint removers, powder solvents, bore cleaners and other strong industrial solvents. The low curing temperature prevents possible heat damage to parts during the curing process. We select our phenolic base stocks from hundreds offered by Dow Corning and 3M. The combination of the most suitable base stock, our additives, and molybdenum creates a truly unique coating that represents state-of-the-art technology. No other thermally cured firearm finish available on the market today has the same characteristics and properties that Moly Resin™ offers the professional gunsmith or home hobbyist. Moly Resin™ is a coating developed for ordnance usage on equipment and weapons, providing excellent corrosion protection, abrasion resistance and lubricity to meet automatic weapon dry firing requirements after 60 days seawater immersion. Available ready to apply. No thinning or dilution is needed.

Moly Resin™ will adhere to all metals including the following: aluminum, carbon steel, stainless steel, sandblasted and glass beaded metal, cast iron and aluminum, titanium, copper, silver solder, blued or parkerized finish, anodized, nickel and chrome plate, and many plastics, etc. Note: nickel and chrome plated surfaces should be abrasive blasted to allow the best adhesion of the Resin. For all metals, best overall results are achieved on freshly sandblasted surfaces. Moly Resin™ is available in the following twelve standard colors but other colors may be special ordered.

A note about the difference between a typical paint and coatings like Moly Resin™. A typical paint is a formulation of pigments and other ingredients diluted with a solvent. When the solvent evaporates, the pigments harden and that hard residue is what is referred to as paint. Unfortunately, paint is susceptible and damaged easily and removed by many, if not most chemical solvents, acids, gun cleaners, bore cleaners, etc. A coating like Moly Resin™ thermally cured or air cure coatings are actual a complex mix of phenolics, polymers, etc. that are highly reactive to each other but kept from reacting by a catalyst mixed into the coating formula. The catalyst is activated by heat at a certain temperature or by oxygen as in the Air Dry Moly product. Once the catalyst is activated, a chemical reaction occurs between the various chemical to form a totally new substance. The new substance formed becomes very hard and resistant to the original solvents used to dissolve the original phenolics and other base resins, etc. This is why Moly Resin™ is not considered to be a paint.

Characteristics and Benefits

MOLY RESIN Coatings...

Moly Resin™ was specifically designed for firearm owners. In the past, a similar finish was obtainable only by vatting or plating your firearm. Now, finally a product that can easily be applied in your shop or at home. Simply degrease, pre-heat part(s), spray with Moly Resin™ , and cure in your oven for one hour. Moly Resin™ can also be applied over existing finishes such as bluing, parkerizing, anodizing, plating, etc. or on a sandblasted surface. The coating adheres to all metals and most plastics.

Specifications:

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

Thickness:
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

Lubricity:
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:
Hardness meets and/or exceeds the hardness of any Epoxy, Teflon or most other thermally cured firearm coating or paints on the market.

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.

Refinishing Procedures

Pretreatment: All Metals
The surface of the parts to be coated should be clean and free of any oils, solvents, etc. Best cleaning methods appear to be soap and water; however, a chemical cleaning with MEK, acetone, etc. is also acceptable. The dullest finish for each color is achieved by abrasive blasting the parts with 90 grit media before coating. This will give the best coat bonding and adhesion, as well as, uniform texture. Sandblasting removes minor scratches and metal surface imperfections. Chrome or nickel-plated parts should always be sandblasted for best adhesion. After sandblasting, rinse parts off with soap and water to remove sand dust and oil from the air compressor. In regard to air pressure used to abrasive blast the metal, use low pressure of 40 to 50 psi for aluminum and 60 to 80 psi on steel. For steel that is rusted, you may need to boost the pressure to 100+ psi.

Application Procedures  All Metals
After sand blasting and cleaning, the part(s) should be preheated in an oven long enough to get the parts to a temperature of about 100 f. Shake the bottle very well to remove all residue from the bottom of the bottle. Remove parts from the oven and lightly spray Moly Resin™ on the part(s) through an airbrush. Apply the coating from numerous angles and directions. Several light fog passes are more preferable than attempting to coat the part in one heavy coat. When warm parts are sprayed the liquid solvent will immediately be evaporated upon contact resulting in a very consistent finish. If parts cool down during spraying, you may return the partially sprayed part(s) to the oven for preheating back to 100 f. For a more dull or flat appearance, the parts may be pre-heat up to 300 f, however, this is not advisable with the semi-gloss black product unless a flat appearance is desired. The best semi-gloss appearance is achieved by pre-heating no warmer than 100 F. Please note that the temperature catalyst in the Moly Resin line of products is set to start the curing process at a temperature that is not harmful to aluminum, steel, other metals and many plastics. Springs are not annealed (softened) at temperatures of 300 f or less.

Curing Procedures  All Metals
After part(s) are coated with Moly Resin™ they should be cured in the oven at 300 F. for one hour. Heating metal firearm parts to 300 f. will not harm them. Please note that Moly Resin is not a paint and unless heated will dry but not harden. Parts should be coated in light oil immediately after cured and cooled. The oil will improve the appearance of the dry cured coating and prevent marks, etc. from occurring when handling newly cured parts for assembly.
