Aerosol Duster, which is commonly referred to as “canned air”, “compressed air”, and “dusting gas” is used to dislodge dust and dirt with a pressurized blast. On a production line, it’s not unusual to see compressed air lines dropped for this purpose. While the air is free, compressed air lines are inflexible, so not as useful for small product assembly operations, repair centers, or field repair. That’s where duster shines!

Prep work and Color Offerings:High gloss is no longer an option! Prep work is now required on every component. If the part is polished, it will still have to undergo blasting operations. SATIN FINISH ONLY!!  We CANNOT guarantee color matches to other manufacturer coatings! Please note that the depth and vibrancy of the color can vary depending on the metallurgical makeup of the component and the type of surface the coating is going on.

Chemtronics offers aerosol dusters with even higher spray force by controlling output through the valve and spray head. Ultrajet® Duster generates about 60% more force compared to other HFC-134a dusters. Ultrajet® 70 Duster clocks in at over 40% greater force than standard HFC-134a dusters. These provide an extra boost to push out heavier particles and anywhere more aggressive cleaning is required.

Yes, HFC-134a and HFO-1234ze are two commercially available aerosol dusters, or “canned air”, that are nonflammable. They are popular in professional or industrial applications because of the safety advantages, especially when used on energized circuits. When there is the possibility of sparks or flames (e.g. spraying high voltage electrical devices), HFC-134a and HFO-1234ze are the best options.

DLC coatings are formed when ionized and decomposed carbon or hydrocarbon species land on the surface of a substrate with energy typically 10-300eV. DLC films may possess exceptional mechanical (high hardness), optical (high optical band gap), electrical (high electrical resistivity), chemical (inert) and tribological (low friction and wear coefficient) properties and can be deposited at low substrate temperatures (~200°C).

Each propellant type used in aerosol dusters has potential to produce a specific amount of force.  HFC-134a has the greatest potential, HFC-152a next, and HFO-1234ze a distant third.  Roughly speaking, the HFC-152a has about 10% less potential to generate force compared to HFC-134a, and the HFO-1234ze has about 33% less potential to generate force compared to HFC-134a.

Chemtronics offers Typhoon Blast 70 Duster, which contains HFO-1234ze (trans- 1,3,3,3-Tetrafluoropropene, CAS #29118-24-9).  HFO-1234ze is nonflammable and has a very low GWP of less than 1, so below the global warming impact of CO2. This is far below HFC-134a and HFC-152a, and still has the advantage of being VOC-free.

As you can see, the aerosol can may be the same size, but the number of sprays for the money can vary widely. This method of comparison isn’t as accurate when comparing different propellants, because the basis weight of each is different. In other words, a heavier material may offer fewer sprays per ounce.

DNA Firearm Systems is not responsible for component failures/damages after DLC service application. During DLC application, components will be exposed to temps up to 450° F and undergo sandblast operations. It is the customer’s responsibility to ensure that the component can endure these processes. DNA warranties DLC application for 30 days after receipt of service. Expect DLC to wear down to raw finish in high-wear areas over time. DLC breakdown is a positive reaction. Carbon deposits are being placed and will increase component functionality.

In the realm of firearms, particularly pistols, advancements in technology and materials have significantly enhanced performance, durability, and aesthetics. One such breakthrough is the application of Diamond-Like Carbon (DLC) coatings. This innovative technology offers a multitude of benefits to various components of a pistol, ensuring not only longevity but also superior functionality. In this blog, we’ll delve into the specific advantages of DLC coatings and which parts of a pistol benefit the most from this cutting-edge application.

Improved AestheticsBeyond functional benefits, DLC coatings also enhance the visual appeal of pistols. The coating provides a sleek, soft black/dark grey finish that is both attractive and non-reflective, making it ideal for tactical and concealed carry applications. We can perform this service in various methods to achieve the desired look you are after. This is all performed during the preparation stages of the application. If we bead blast the piece, it delivers a matte finish. If the piece is polished, we prepare the piece for DLC application in a proprietary formula of chemicals rather than bead blasting the surface. Upon the completion of DLC application, the component will have a glossy dark black finish.

Carbon, in a diamond crystal structure, is one of the hardest known materials. Carbon, in a graphite crystal structure, is very soft and lubricious. Carbon-based coatings, referred to as Diamond-like-Carbon (DLC) coatings, combine these two different properties of diamond and graphite – resulting in high hardness levels – in the range of conventional tribological PVD coatings, coupled with a coefficient of friction which is 200-500% lower than that of conventional PVD coatings. DLC Coatings exhibit a desirable combination of a low coefficient of friction and high micro-hardness, making them extremely effective in many tribological and wear applications. DLC is such a durable and lubricious coating it is also used in the engines of modern Super sport Motorcycles, Drag Racing Cars, Formula 1 and NASCAR Race Cars that undergo extreme abuse yet need to maintain superior performance.

Chemtronics offers Ultrajet® All-Way Duster, which is specifically designed to spray only gas as you rotate the can. It also sprays with a very high force to dislodge stubborn contamination.

To achieve the optimum force out of a can of duster, spray short three- to five-second blasts at room temperature. When an aerosol duster is sprayed continually, it acts as an efficient heat sink and will cool down. This lowering of the can temperature also lowers the internal pressure of the can, which will greatly decrease the generated force.

Because of how the valving of aerosol dusters, or “canned air”, are engineered, they generally can only be sprayed right-side-up or, at most, a 45º angle. Under high pressure, the propellant is mostly liquid, with the empty part of the can filled with vapor. When you spray an aerosol duster, the vapors of the propellant are expelled. As you rotate the can, the liquid starts to spray out and at a very low temperature (as low as -60ºF / -51.5ºC). In some cases, such an extreme temperature swing can damage sensitive components or draw in moisture where you don’t want it.

Pistol FrameThe frame of a pistol, especially in polymer models, can benefit from DLC coatings applied to metal inserts or components within the frame. This ensures better durability and a longer lifespan for the parts that handle the most stress. It can be beneficial for coating application to the frame as well as the various small pieces, but the frame must be of a metal substrate.

Pistol SlideThe slide is one of the most critical parts of a pistol, as it houses the barrel and other internal components. Applying DLC to the slide significantly reduces wear from constant cycling and improves the overall smoothness of the action. Additionally, the enhanced corrosion resistance ensures the slide maintains its integrity and appearance.

DLC is very durable yet thin-film coatings. DLC coating is used to reduce wear on critical components while drastically improving durability. Friction is reduced and general functionality of components is increased.

Aerosol dusters, or “canned air”, can be purchased from commercial / industrial distributors like Hisco or Grainger, but are also commonly sold through big box stores like Walmart, Home Depot or office supply stores like Office Depot. While the temptation is to buy the lowest cost duster, it is important to be aware of the trade-offs. Low cost dusters available at consumer stores can have a negative impact on worker safety and your product reliability.

The application of Diamond-Like Carbon coatings to pistols represents a significant advancement in firearm technology. By enhancing durability, reducing friction, providing superior corrosion resistance, and improving overall aesthetics, DLC coatings ensure that pistols perform better, last longer, and look great. Whether for professional use, competitive shooting, or personal defense, DLC-coated pistols offer unmatched benefits that elevate the firearm experience to new heights.

To avoid disassembly and reassembly fees, everything needs to come to us completely disassembled. If we receive a package and the components are not completely disassembled, we will reach out to you beforehand to determine next course of action and what charges will be incurred to get the part ready for coating.

Reduced FrictionDLC has a remarkably low coefficient of friction. This property is crucial for the moving parts of a pistol, as it ensures smoother operation and reduces the wear and tear that results from friction. The smoother action also contributes to better accuracy and reliability.

DLC is an extremely hard coating that provides extreme hardness, strength, wear resistance and the coating is only 4 microns thick. The ultimate goal is more than just a coating the yields strength and reliability. Gas guns can get extremely dirty, (especially when used suppressed). The motive behind offering DLC application on most components that we offer is to aid in extremely fast and simple clean up. Therefore, more time in the field, and less time cleaning.

Yes, please disclose to us upfront if your pieces are coated!! Silica based coatings can damage certain chambers and will need to be prepped alternatively.

Aerosol dusters predominantly come in a steel can with a plastic trigger sprayer. It is possible for the sprayer to become charged from either handling or from the propellant being discharged, so may be a concern for cleaning sensitive electronics. The Chemtronics Ultrajet® Duster System includes a chrome trigger sprayer and a refill can with a threaded valve. The sprayer can be reused with refill cans that are sold separately. The advantage of the chrome sprayer is more precise spray control and ESD (electrostatic discharge) control. The chrome trigger is conductive, so will not build up a charge, and has the potential of being grounded. For example, if the user is grounded by a wrist strap, the sprayer and can be grounded as well if in good contact with the person’s hand.

Enhanced DurabilityOne of the most significant benefits of DLC coating is its exceptional hardness. This hardness translates to increased resistance to scratches, dents, and other forms of wear. For pistols, which are often subject to rough handling and environmental exposure, this means that the weapon retains its functional and aesthetic qualities for a much longer period.

No, this is a misconception based on old information. Dusters contained CFCs (chlorofluorocarbon) over 20 years ago but have since been replaced with materials that do not impact the ozone layer. In North America, there are no commercially available aerosol dusters that contain ozone-depleting propellants.

In contrast to the nicknames “canned air” or “compressed air duster”, aerosol dusters contain a refrigerant or propellant that cannot, in any way, be considered breathable air. In fact, you should have proper ventilation when using duster as you would any other aerosol product.

Turnaround Time: Typically 6-8 weeks depending on volume. We will typically run monthly batches for outside orders. Please prepare accordingly and be aware of this lead time. We do not offer expedited services on coatings. Lead times could be more extensive for anything outside of DLC.
