Additives to Combat Product Piracy
How do you distinguish a product often designed with great development effort from a cheap copy? For manufacturers of high-quality plastic products, this question is gaining increasing urgency against the background of globalized economic relationships and ever more cases of copyright infringement.
A solution developed by Rowa Masterbatch GmbH, Pinneberg, Germany, allows almost every plastics processor to protect its products against counterfeiting without expensive mold changes or additional process steps.
Invisible identification is integrated by incorporating special additives during production. Irradiating the modified part with a suitable test beam causes an immediate change in its surface properties, with the irradiated area appearing red. The test beam is a compact, easy-to-use laser, similar to a conventional laser pointer.
The additive can be introduced either as a pure additive batch or a combination batch also containing color pigments and functional additives. Since only a very low concentration is required, there is very little impact on the part’s cost and its optical and mechanical properties are not affected.
