SpeedMask® Light-Curable Maskants

Replace Tape, Wax, Lacquers, and Fixtures

SpeedMask® is a line of Dymax light curable temporary masking resins that offer reliable surface protection not available from traditional masking materials such as tapes, lacquers, and waxes. SpeedMask light curing masking resins are available in several viscosities, which can be quickly applied by syringe or through dipping, spraying, or screen printing. Residue-free removal is achieved with peelable, water-soluble, or burn-off grades. They cure upon exposure to light energy.

SpeedMask masking resins are used in surface preparation and finishing operations where a barrier is needed to protect surfaces and cavities. SpeedMask masking resins are successfully being used in many industries, including aerospace, power generation, metal finishing, and the manufacturing of orthopaedic implants and medical devices.

Dymax SpeedMask masking resins contain no non-reactive solvents and cure in seconds, providing cost savings through reductions in labor, rework and scrap. They are preferred over traditional masking materials such as waxes, tapes, and lacquers due to ease of application, superior protection with consistent reliability, and fast cure time.

SpeedMask® Light Curing Temporary Masking Resins for the following processes


Anodizing masks feature chemical resistance for better surface protection of components from the strong acids used in the anodizing process. Cured SpeedMask resins protect substrate surface while the oxide layer of coating (which changes the microscopic testure of the component surface) is applied. These materials can tolerate most Type I (Chromic Acid), Type II (Sulfuric Acid), or Type III (Hard coat) anodizing processes.


Plating masks feature chemical and heat resistance and provide superior surface protection of components during plating processes where particles are deposited onto conductive surfaces. SpeedMask resins are able to withstand the most common plating processes such as Electroless Nickel (Ni), Platinum (Pt), Chrome (cr), Gold (Au), Silver (Ag), and Copper (Cu). Plating masks are available in low, moderate, and high levels of adhesion to accommodate the various operating temperatures of plating baths.

Acid Stripping

Acid stripping masks withstand soaking in hot acid without permeation or seepage under the mask. When cured, SpeedMask resins provide superior surface protection from chemical processing of nickel super alloys, steel, and titanium. They hold up to the surface preparation of grit blasting, which may be required prior to, or in combination with, the hot-acid soak. These masking resins can tolerate most acid soaks such as Hydrochloric (HCl), Nitric (HNO3), Acetic (CH3COOH), Phosphoric (H3PO4), Hydrofluoric (HF), or various combinations of the acids.

Chemical Milling/Etching

Chemical milling masks have enhanced chemical resistance and superior surface protection from the strong acids and alkalis used in dissolving metal substrates during the chemical milling process. Cured SpeedMask resins can be trimmed to provide defined edge boundaries and accommodate the most complex and intricate components, while still providing excellent protection with no leakage. These resins withstand the typical 200°F+ Nitric Acid (HNO3) and Hydrofluoric Acid (HF) solutions used for the chemical milling of titanium components and typical Sodium Hydroxide (NaOH) and Potassium Hydroxide (KOH) solutions used for the chemical milling of aluminum components.

Air Plasma Spray and HVOF

Air plasma spray masks provide superior surface protection during thermal barrier coating processes. SpeedMask masking resins are resistant to the aggressive force and heat to flame-spray processes. The cured masks absorb the enerty from the force of plasma spray materials, such as zirconium, Molybdenum (used for thermal protection), Tungsten Carbide, or ceramics used to wear-resistant coatings. As the melted particles from the flame spray are deposited onto the substrate, the cured masking resin protects the surface underneath the protected area.

Painting, e-Coating, and Powder Coatings

SpeedMask masking resins offer superior surface protection of components during painting, e-coating, and powder coating, and are resistant to the heat and chemical exposure during these processes.


Machining, buffing/polising, and laser drilling masks provide excellent protection during the milling, grinding, drilling, polishing, and turning of turbine and metal components, orthopaedic implants, surfical instruments, medical devices, as well as glass and plastic substrates. The durabiligy of the cured SpeedMask resins allow the maskants to be machined through, without any lifting of the remaining masks, while continuing to provide reliable protection of the masked surfaces. These resins can withstand various water-soluble and oil-based coolants used in machining, as well as absorbing the energy from laser drilling during the installation of cooling holes.

Airflow Testing

When cured, SpeedMask airflow-testing masks allow for complete sealing of cooling holes and core cavities of turbines and components, for either row-by-row or mass airflow testing. They also provide complete sealing, preventing air leaks during pressurized flow, leak, and duration testing.

Grit Blasting

Grit-blasting masks are resilient to both smooth and sharp particles and the pressure used during grit-blasting surface treatment. Cured SpeedMask resins provide reliable protection from media such as aluminum oxide, garnet, plastics, and organic media. The cured resin absorbs the energy from the air stream blast, while the media bounces off the masked surface, protecting the area underneath.

Shot Peening

Shot-peening masks have superior surface protection during the shot-peening, plastic-deformation surface-treatment process. Cured SpeedMask resins are resistant to various peening media (such as cut wire, round metal, ceramic particles, and glass beads) and the pressures used in peening applications. The cured resin absorbs the energy from the ball-peen hammer effect of the media blast, while the media bounces off the masked surface, protecting the area underneath.

Vibratory Finishing

SpeedMask resins provide reliable surface protection of intricate and complex configurations during vibratory finishing operations such as slurry, tumbling, or deburring. These masks withstand the compound solution (soap, water, or alternative cleaning/polishing agents) and abrasion from ceramic, plastic, or steel media while vibrating during the finishing process.

General Masking

SpeedMask masking resins feature superior surface protection of turbine and metal components, orthopaedic implants, surgical instruments, and other medical devices from FOD (foreign object damage) during the manufacturing process, handling, and transportation.
