One company – two divisions

To better adapt to the needs of the market and thus achieve greater customer intimacy, we decided to divide our business in two divisions: DONIT® Gasket Sheets and DONIT® Industrial Sealing Solutions (for gaskets and solutions). This enables us to offer complete range of sealing products and solution and at the same time better fulfillment of different customer needs and better adaptability to market demands.
