launched Voltacast 3310/Voltacast H134, a new epoxy-based casting resin system that expands the Voltacast product portfolio of casting resins from Axalta’s Energy Solutions business.
Voltacast 3310 is specifically designed to offer high thermal stability in combination with high thermal conductivity for winding head encapsulation or total stator encapsulation of electric motors, like servo drives or large machine tools.
“Voltacast 3310 ensures outstanding resistance to a variety of automatic transmission fluid oils used in electric vehicles, and its high thermal conductivity in combination with oil cooling of electric motors allows maximum heat dissipation," said Christoph Lomoschitz, global product manager for Axalta’s Energy Solutions business.
Voltacast 3310/Voltacast H134’s anhydride-free system can be cured at room temperature or preferably at temperatures up to 70ºC. The cured material is flame retardant, fulfilling the requirements of Underwriters Laboratories (UL) standard 94, class V0, and will shortly receive official UL recognition.
The new Voltacast 3300 range is comprised of two-component systems – an epoxy resin and a hardener.
The products of the Voltacast 3300 range offer superior thermal conductivity, from 1.2 W/mK up to 1.6 W/mK, without compromising an easy and safe application, as the processing viscosities are only 2200 mPa*s to 2400mPa*s at room temperature. The new Voltacast materials are very versatile, with glass transition temperatures of 24ºC, 60ºC and 95ºC, depending on the final application requirements.
