The OPN-CHEMIE GmbH was founded in 1948 by Mr. Otto Petri as a sole proprietorship and from 1953 continued and expanded by Mr. Ehrfried Petri. It dealt among other things with the production of mining equipment and chemicals for the local ore mining. In 1967 Mr. Thomas Petri joined the company. The field aerosols for automotive, trade and industry was set up in 1978 by Mr. Thomas Petri and constantly expanded. In 2018 we celebrate “40 years of aerosols of OPN-CHEMIE”. In 1993, Thomas Petri took over the company and continued it as a sole proprietorship Otto Petri – owner Thomas Petri. In 1998, the sole proprietorship Otto Petri – owner Thomas Petri was transformed into OPN-CHEMIE OTTO PETRI GmbH. Since December 2016, Mrs. Barbara Angelika Gros-Petri is the sole owner. There are currently about 20 employees. Technical sprays that are manufactured with a high standard of quality are the core business of the company. A complete control and quality assurance system, as well as qualified personnel, always ensure consistent qualities, which are distributed worldwide. The product range currently includes a few hundred products and is constantly expanding. Also contract filling of provided liquids are possible without any problems. Since January 2017, customer-specific labels, even for small orders, can be created in-house and printed in 4C in color. In June 2020 the company name was changed to OPN-CHEMIE GmbH.
