Fluorescent Safety Markers

RADOMEC has a group of inorganic and inert markers (solid nanometric marker MARK m and ink marker MARK s) that have been tested on various metals such as Iron, Steel and Metal Alloys, Gold, Precious Crystals, Plastics. These markers are added to the product we wish to label, being inert and resistant to high pressures and temperatures. When inserted into the product to be marked, it is not visible. Under the action of a Laser Light it can be identified by the characteristics of the emitted light. We have developed a large number of these markers, which can provide product marking in batches or individual units.
These markers have a broad fluorescence spectrum that allows you to cover a wide visible spectrum that can be used in product safety marking.

We also have inks containing these markers (MARK s series) that can be used in product safety prints. These marker components are inert and stable, have been tested to varying degrees of proportion on various materials from concentrations of 1 / 20,000 to concentrations of 1/10 without any interference with the appearance and quality of the marked item.
RADOMEC has a variety of hundreds of variants of this family of markers that make it possible to control the origin of the product. These markers are unique with optoelectronic (fluorescent) spectral identity that ensures identification of the labeled product and its officially certified origin. They are added to the product during its manufacture or handling and enable the identification of various products that can be detected later, with the incidence of a test laser and confirmation of the presence of the marker. We have several families of markers (nanometric marker MARKm and MARKs safety inks), which after application in the industrial process enable the definitive later identification of the marked product.

Gold Safety Marking

The marker was used to identify the origin of gold plates manufacturing. In the video below we have the gold fusion, where is added the marker MARK1, during the fusion process.

As a result of this process, we have the gold bars molding where the marker is not visible.

After this process we can identify the marker (green color) on all molded gold pieces.

Without the presence of the laser, no fluorescence is observed. The gold trading industry can identify your 'branded' product even if it is melted and new parts are produced.

Plastic Markers

Several plastics were manufactured with the addition of markers. It perfectly suits the production of plastics from various sources. In the figures below we have the detection of the resulting fluorescence when the laser hits the plastic.

Marking ff Jewelry, Precious Crystals and Accessories

An ink containing the MARK1 marker was used for the purpose of marking the surface of a zirconia crystal for safety purposes.

To this end, a zirconia crystal was marked with two drops of the transparent ink solution (MARKs) and then the stone was heat treated. After heat treatment, no variation in color or appearance of the stone is observed. However under the action of the laser we can identify the presence of the marker in the crystal of Zirconia. The observed green color refers to the inorganic marker MARK1 present in zirconia. This marking is permanent and no withdrawal is possible. This marker has been successfully tested on different gems.

The same procedure was tested on commercial metal parts (chains, pendants etc) in the accessories area. In all of them the marker was successfully inserted and later detected.

Metal Markers

Several metals were tested with positive labeling results. In the picture below we have the marking of metallic scissors.

Several metallic cylinders used for gas conditioning have been tested with positive results. In the figure below we have the marking of oxygen metal cylinders. The figure below shows the photos of the marked cylinders when subjected to laser excitation. Here you can see the presence of a green color that is characteristic of the MARK1 used in the tests.
