Quality and the Environment

Sustainable Balance Sheet: it gives you an overview of the different areas in which we support sustainability topics.

People from the Harz Mountains have alwas been in tune with nature as they did not want to ruin the basis of their ecenomy. Trees for wood as a raw material for mining and metallurgy were planted for future generations as early as the 15th century. Even back then, people managed their resources in an ecologically sound manner, long before the word "sustainable" was on everyone's lips.

Located at the outskirts of the Harz Nature Park, we feel an obligaion to protect the environment and, in 1998, we were certified in accordance with DIN EN ISO 14001.

Water-dilutable products account for 60 % of our total production - with a strong tendency to rise.

Technologies that were invented for eco-friendly toys are now being used for "normal" coatings in order to continuously improve the eco-balance.

"Quality means that the customer returns - and not the product."

We would be happy if you return to us! This is why we continuously work on the further development of our coatings in order to provide you with optimum solutions.

Our quality management has been certified in accordance with DIN EN ISO 9001 since 1997 (certificate register number 08 100 1790 by the TÜV CERT- certification centre of TÜV Nord VERT GmbH & Co. KG).

The current DIN EN ISO 9001 and DIN EN ISO 14001 certificates ca be downloaded in German, English, and Russian here.

Major companies regularly classify our company as a "category A supplier". In 2003, the environmental and quality management sectors were combined in a certified integrated management sstem (IMS).
