Company profile

Maldaner GmbH originated from a private company founded in February 1962 as a trade agency for metal impregnation. The following year, in October 1963, the first job-shop for sealing castings was opened in Düsseldorf.

The superiority of the new sealants, which were introduced by Maldaner, gave the industrial users, within a short time, an important advantage of quality. This consequently led to a rapid expansion of the company. The one-man operation has grown into being the largest group of companies specialized in metal impregnation in Europe.
