Cermark

NOTE: ⚠️ Best Practices for Using Laser Marking Sprays
When working with laser marking materials, it's generally not recommended to use multiple types interchangeably during the same workflow. Each product—such as Cermark or Laser Bond 100—requires its own specific laser power and speed settings, which can lead to inconsistencies and operator confusion if changed frequently.

If your operation involves short production runs or frequent material switching, it's best to stick with one laser marking material that consistently delivers the results you need. However, if you're handling longer production runs on the same type of surface, you may benefit from experimenting with different marking compounds to achieve optimized contrast, durability, or speed for specific applications.

Cermark vs. Laser Bond 100: Laser Marking Sprays Compared
1. Marking Quality and Durability
Cermark

Produces high-contrast, jet-black marks.
Known for its excellent durability, abrasion resistance, and resistance to chemicals and UV exposure.
Commonly used in aerospace, medical, and industrial settings where permanence is critical.
Mark is fused to the surface and often outlasts the material itself.
Laser Bond 100

Also creates permanent black markings, but depending on the substrate and settings, it may be slightly less dark or sharp than Cermark.
Still provides good durability, but some users report slightly less resistance to harsh environments.
Suitable for most standard marking needs including industrial tools, electronics, and ID tags.
“We use Cermark when we're marking high-value components that need to pass rigorous QA checks. For everything else, Laser Bond gets the job done at a lower cost.” — Industrial Fabrication Manager

2. Application and Ease of Use
Cermark

Available in aerosol, paste, and tape form.
Aerosol version requires vigorous shaking and thorough cleaning of the surface.
Takes longer to dry, which may slow down high-volume jobs.
Laser Bond 100

Also comes in spray and liquid.
Known for quick drying time and easy cleanup.
More forgiving with less stringent prep requirements, making it beginner-friendly.
“Laser Bond dries faster and is easier to remove if you make a mistake. It's great for prototyping.” — Small Batch Laser Shop Owner

3. Laser Compatibility
Both work with CO₂, fiber, and diode lasers. However:

Cermark is slightly more optimized for CO₂ lasers, especially on stainless steel.
Laser Bond 100 performs consistently across a broader range of materials, especially aluminum and glass.

4. Material Versatility

5. Cost Comparison
Cermark is more expensive per can or bottle.
Laser Bond 100 is generally 25–30% cheaper, which can make a significant difference in large-scale operations.
The yield per can is similar, but Cermark’s slower drying may reduce throughput.

6. Environmental and Safety Factors
Both materials require proper ventilation due to the fumes created during marking.
Laser Bond 100 claims to be more environmentally friendly, with fewer VOCs and safer handling instructions.
Neither product is food-safe unless further certified.

7. Which Should I Choose?


Stats & Research
According to a 2023 comparative test by LaserTechReviews, Cermark achieved 92% black density on stainless steel, compared to 87% for Laser Bond 100.
In a 500-mark abrasion test, Cermark retained legibility in 98% of samples, while Laser Bond 100 retained 94%.

Final Thoughts
If your priority is maximum performance and longevity, Cermark remains the industry gold standard. But for most practical purposes—especially where speed, ease of use, and cost are more important—Laser Bond 100 is an excellent alternative. For many shops, having both on hand makes the most sense.
