BASF Engelhard SorbeadTM Orange CHAMELEON®
Indicating silica gel for moisture control, also known as KC-Trockenperlen® Orange CHAMELEON®
BASF Engelhard SorbeadTM Orange CHAMELEON® indicating silica gel is the newest adsorbent technology from BASF. BASF Engelhard Sorbead Orange CHAMELEON is used where processes and products need to be protected from the negative consequences of humidity and moisture.
Similar to our BASF Engelhard SorbeadTM R adsorbent, BASF Engelhard Sorbead Orange CHAMELEON is a beaded silica gel with very high mechanical integrity. It meets the demand for a heavy-metal free and environmental friendly indicating agent.
With a new and improved indicator, BASF Engelhard Sorbead Orange CHAMELEON provides safe moisture indication without any concerns regarding carcinogenic ingredients. It also provides superior moisture indication with a crisp color change.
The degree of moisture uptake is indicated by a color change from orange to colorless at approx. 6 wt % water content. However, it continues to adsorb water from this point until reaching its maximum capacity.
BASF Engelhard Sorbead Orange CHAMELEON regains its full adsorption capacity when regenerated. Its unique formulations ensures advanced stability against harmful UV-rays.
Typical applications for BASF Engelhard Sorbead Orange CHAMELEON are transformer air breathers as well as other breather filters, laboratory uses, packaging of moisture sensitive goods and many others.
