OMTech Laser Marking Spray
OMTech’s laser marking spray provides a high-contrast, permanent black result on bare metals when used with CO2 lasers of 25W or higher, and more vivid outcomes with fiber lasers. The formula starts white and turns black upon laser interaction, enabling clear, durable markings on aluminum, stainless steel, brass, and other metals. The 13-ounce aerosol can includes a clog-proof nozzle for even spray distribution, ensuring a thin, smooth coat on metal surfaces. This makes it suitable for personalizing jewelry, tumblers, serializing tools, and other metal projects.
xTool Black Laser Marking Spray 2.0
xTool Black Laser Marking Spray 2.0 offers an upgraded formula that yields permanent, high-contrast black markings on metals, ceramics, and glass. It is designed for broad laser compatibility, with recommended use instructions emphasizing proper shaking and handling. The product is compatible with CO2 lasers (25W minimum), fiber lasers (10W+), and diode lasers (10W+), enabling professional results across a wide range of laser machines. The manufacturer provides operational guidance to optimize coat quality and engravings that resist fading over time.
CerMark Ultra Laser Marking Aerosol
CerMark Ultra is formulated to enhance laser bonding on metal, ceramics, glass, stone, and related substrates. It supports deep, durable black marks across a range of laser power settings, including faster CO2 settings. The coating is designed to avoid tarnish or staining on sensitive metals such as brass and copper, making it a versatile option for mixed-metal projects and surfaces that demand stability under varied processing conditions.
Brilliance Laser Inks 2 Oz Aerosol
This Brilliance Laser Inks formula targets metal marking on uncoated surfaces like stainless steel, brass, copper, and other metals. It is designed for compatibility with CO2 (25W+), fiber/YAG (10W+), and diode lasers (10W+). The application is straightforward: clean with denatured alcohol, shake, spray from 6-8 inches, etch with the laser, and rinse for clean results. The product emphasizes versatile metal compatibility and ease of use for consistent high-contrast marks on a range of metals.
Brilliance Laser Inks 12 Oz Laser Marking Spray
The Brilliance Laser Inks 12 Oz option provides a larger can for higher-output projects, featuring copper-tone red or black metal marks suitable for CO2, fiber, YAG, and diode laser systems. The product is designed for universal metal marking on uncoated surfaces, with the same underlying principles as the smaller can: compatibility with major laser families, controlled application, and durable results that resist wear from handling and cleaning processes. It is presented as a scalable solution for batch engraving or higher-volume production runs.
Buying Guide: Key Purchase Considerations And Comparisons
- Metal compatibility: Most options list stainless steel, aluminum, brass, and similar metals. Confirm if your target materials include coated or composite metals, as some formulas are optimized for bare metal.
- Laser type and power compatibility: Check whether the spray is formulated for CO2, fiber, or diode lasers, and the minimum wattage recommended. This ensures reliable marking with your specific equipment.
- Marking quality: Look for claims of high-contrast, permanent black marks that resist fading and tarnish. Higher-contrast results generally improve legibility and durability in real-world use.
- Application and drying: Many products require shaking, 6-8 inch spray distance, and a drying time. Consider dry times for batch work or high-volume production and whether the product includes a clog-proof nozzle.
- Safety and handling: Note any instructions about ventilation, protective gear, or storage conditions (avoid sun exposure, etc.).
- Volume and value: Can sizes range from 2 oz to 12 oz. For hobby projects, smaller cans may suffice, while production settings benefit from larger cans to reduce replacement frequency.
- Brand credibility and support: Reputable brands with documented usage guidelines and customer support can help optimize results and troubleshoot issues.
- Color options and permanence: Some sprays yield black marks, others offer copper tones or red hues. Consider the desired aesthetic and longevity for your projects.
