Darmstadt, Germany, June 22, 2017 – Merck, a leading science and technology company, will present a new pigment for laser marking in a new application field at the Laser World of Photonics 2017 exhibition from June 26 to 29 in Munich. Iriotec® 8826 is particularly suitable for dark and high-contrast marking of colored polymers and for the first time enables the laser marking of films.

Invisible – but highly effective
A poster hanging at the Merck stand asks “Can a material disappear, while its function remains?”. The answer can be found at the booth: The product innovation being presented, Iriotec® 8826, is a pigment powder that can be incorporated into a polymer with neutral color impact. Its effect is invisible until an infrared laser is used. The marking is so quick that the surrounding material remains unaffected by the light while Iriotec® 8826 generates a dark, high-contrast marking even at low concentrations. The new laser pigment can be used to label cables with different colored sheaths, for instance, which provides permanent, reliable orientation in big bundles of cables.

The fast reaction time of Iriotec® 8826 also opens up a completely new application: This pigment can be used to permanently label films with laser light – without damaging the material in any way. The combination of PE film and infrared laser is thus unique.

All advantages of laser marking
This new product also offers all the advantages of the full range of Iriotec® 8000 laser pigments from Merck KGaA, Darmstadt, Germany. The marking is embedded in the material and not on the surface. It is permanent and cannot be removed, and it is efficient and cost-effective because it is created without the need for consumables or for surface preparation.

Industry experts attending the Laser World of Photonics 2017 can experience this pigment innovation from Merck KGaA, Darmstadt, Germany, and its application possibilities in Hall A3, Stand 415.
