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.
