markSolid marking sprays and pastes

Create permanent, black markings on metals, glass and ceramics with a CO2 laser

By applying the spray or paste on the blank surface (metal, glass, ceramic), CO2 lasers, as well as fiber or Nd:YAG lasers, produce a permanent black marking. This marking is highly resistant to mechanical and chemical stresses as well as high temperatures. High contrast and resolution can easily be achieved. Marking sprays and pastes are very popular for all applications that require high contrast and durability - making markSolid products ideal for bar coding, product serialization, logos and decorative marking.

Learn how to use markSolid marking sprays and pastes:

prepare the sheet of metal for applying the marking product
1. Preparation

Product needs to be applied directly on the blank surface. The surface has to be dry and clean, free of dust, grease, silicone, etc. Shake the spray well to make sure solid sediments are dissolved. Dilute the paste according to the description on the product label.

apply the marking spray or marking paste on the metal sheet
2. Applying

The more evenly and the more accurately you apply the product onto the surface, the better results you achieve. The principle „less is better“ applies often in regard to the layer thickness. Spray from 20 - 30 cm distance. Apply the paste with brush, foam or airbrush.

let the metal sheet dry
3. Drying

The coating must be completely dry before starting the laser marking. It usually takes 1-2 minutes when dried by air, but a hot air blower (e.g. a simple hair dryer) can reduce the drying time. Tip: You may reduce the drying time by putting the work piece in the laser with exhaust turned on.

4. Laser marking

The products can be used for marking with CO2 lasers, Nd:YAG lasers and fiber laser, to name a few.
Differences in laser power, wave length and other factors influence the final settings required.
After laser marking, excessive coating can be removed by wiping with a damp cloth or by washing with water.
