Pigments are Nano

A webinar by contactpointnano.ch

Nanomaterials are something new and innovative, right? Not necessarily: Certain nanomaterials were already in use in the Stone Age, long before mankind invented the wheel. These materials include color pigments that are incorporated into a filler material to give it a specific color: The ochre and earth tones of prehistoric cave paintings can be traced back to carbon black and iron oxides, the splendid ruby red of medieval church windows to tiny gold particles melted into the glass. And until the 18th-century lapis lazuli dust made blue the most expensive color tone known to mankind.

Today, nanoscale materials are routinely used in the lacquer and paint industry: To give paint water-repellent properties or to provide protection against UV rays, to make it more resistant to scratches and weathering or to protect it from fungal attack. It comes as no surprise that such fillers, lacquers and paints containing deliberately produced synthetic nanoparticles fall under the definition of nanomaterials and are thus also subject to nano-specific regulations. Many companies may be less aware, however, that the majority of pigments and fillers, although produced for decades already, now also fall under the definition of nanomaterials recommended by the EU in 2011 – and that this may be associated with some quite complex verification obligations.
