As an internationally renowned manufacturer and full-service provider of polymer systems, DIAMANT Polymer GmbH offers innovative and high-quality solutions for industrial applications.

Our products preserve values and protect investments. For example, defective castings are not discarded as rejects, but can be “rescued” and made usable by post-treatment with special polymer systems. Good for our customers, good for the environment. Follow us into a new future and discover the wide range of applications for polymer composite materials and the exciting world of technical impregnation and infiltration systems.
