Imp­reg­na­tion resins

Our imp­reg­na­tion resins are the best choice for win­ding insu­la­tion. They offer the best electri­cal, mecha­ni­cal, and ther­mal pro­tec­tion of coils such as those used in pumps, trans­for­mers, EV dri­ves and wind tur­bine generators.

All of our cur­rent imp­reg­na­tion pro­ducts repre­sen­ted by the Dol­p­hon® and Dam­i­sol® brands are UL lis­ted while mee­ting the hig­hest tech­ni­cal requi­re­ments. Our most inno­va­tive resin sys­tems are label-free, hazar­dous mate­rial-free, fea­ture impro­ved heat dis­si­pa­tion and are 100 % resistant to par­tial discharges.

Our exten­sive tech­no­lo­gi­cal base with poly­es­ter, epoxy and sili­cone resins enab­les us to offer cus­to­mi­zed solu­ti­ons to our customers.

Pro­ducts and solu­ti­ons

The trickle and dip rol­ling pro­cess is par­ti­cu­larly sui­ta­ble when short cycle times have to be rea­li­zed, as requi­red for series pro­duc­tion with high output.

Here, our resins of the Dol­p­hon® and Dam­i­sol® series enable a par­ti­cu­larly fast and clean pro­duc­tion pro­cess. This makes them par­ti­cu­larly sui­ta­ble for high-volume indus­trial pro­duc­tion and the auto­mo­tive industry.


Dipping repres­ents a rela­tively simple pro­cess that requi­res little invest­ment and, with the right resin, leads to a good imp­reg­na­tion result. With our Dol­p­hon®, Hi-Therm® and Aqua-Therm® resin solu­ti­ons, fast and high-qua­lity imp­reg­na­tion can be guaranteed.

If hig­her imp­reg­na­tion qua­li­ties are requi­red, as is the case in the pro­duc­tion of medium-sized indus­trial motors or the pre­mium seg­ment in the auto­mo­tive indus­try, the pro­cess of hot dipping is often used. With our novel tech­no­lo­gies and cus­to­mi­zed pro­ducts of the Dol­p­hon®and Dam­i­sol® series, dipping costs can be redu­ced by up to 40 % while impro­ving performance.


Wind tur­bi­nes, gene­ra­tors and trac­tion machi­nes all share the need to ope­rate in harsh envi­ron­ments and pro­vide reli­able ope­ra­tion over a long ser­vice life. These app­li­ca­ti­ons require an out­stan­ding imp­reg­na­tion qua­lity, which is usually achie­ved by vacuum-pres­sure impregnation.

To gua­ran­tee the best imp­reg­na­tion qua­lity, an imp­reg­na­tion resin needs to be pai­red with fine-tuned pro­cess para­me­ters. Our experts offer you an excel­lent resin selec­tion from the Dam­i­sol® series cou­pled with many years of pro­cess expertise.

For the insu­la­tion of machi­nes in extreme envi­ron­ments, we recom­mend our Dami­val® and Dol­p­hon® pot­ting resins using the com­plete sta­tor pot­ting pro­cess. This pro­vi­des opti­mum pro­tec­tion for the electri­cal machine and the best heat dissipation.
