Diamant Metallplastic.

The history.


In 1892, Robert Schulz founded the “Robert Schulz Drogerie” as a chemical trade in the foundry founded by Robert Schulz in Germany in 1886.


From the knowledge of the production problems of foundry products and chemical processes, Robert Schulz is sure to meet the growing demand for metal repair kits. Shortly afterwards, leading foundries in Germany use the first repair mats formulated by Robert Schulz as “cast cosmetics”.


After the First World War the business was expanded and the company changed into “Adler Rheydter Lack-, Spachtel- & Kittfabrik”. Primarily, specialties for the foundry industries are also produced.


After the Second World War, the third entrepreneur generation rebuilds the completely destroyed factory building and changes the company name to “Adler Kitte”.


In 1951, first formulations based on epoxy and polyester resins were produced and used under the trademark “Diamant-Kitte Schulz & Co.”. In the late 1950s, the first trade contacts were established with Eastern Europe.


In the mid-1970s, the company changed its name to “DIAMANT Metallplastic GmbH”, modernized the company’s location in the Rhineland Mönchengladbach and successfully expanded its distribution to America and Asia.


In addition to production, the business areas of consulting and application have been significantly expanded in the 2000s and the company has grown into a full-service partner from consulting on product development and production to product application.

To date, the Diamant Metallplastic, which is still a family business, has been formulated, developed and produced exclusively in Germany.
