Batch for Trademark Protection
Infrared Signatures Protect Originals
In 2010, German engineering industry alone suffered an estimated 6.4 billion loss due to product piracy, according to information released by VDMA (the German engineering association) in Frankfurt. To prevent this fraud, the trademark protection batch offered by Rowa Masterbatch GmbH, Pinneberg, Germany, emits electromagnetic waves at infrared range. The masterbatch uses this range of light invisible to humans, to apply infrared signatures to components. For this purpose, few ppm of a chemically inert mineral pigment are introduced into the plastic material, which then become an invisible and insoluble part of the component. Initially, this pigment is inactive, and will only become active when exposed to a light impulse at IR range. Induced in this way, it returns a certain response pattern. This reaction is composed of one or several light impulses of different wave lengths, and is as specific as a barcode.
The testing device is operated by pressing a button, just as a regular IR remote control. If the part is marked, it will emit a green light, as a response.
