Abstract
For manufacturing molded and impregnated parts from epoxy resin compositions, a reactive epoxy resin is employed which hardens more slowly at higher temperatures (120.degree. to 180.degree. C.) than at lower temperatures (80.degree. to 110.degree. C.). The reactive epoxy resin composition is applied at the higher temperature and subsequently hardened at the lower temperature. According to the method of the invention, molded parts (e.g., solution pump heads), cast-in electrical components (e.g., four-ring stray field electrodes) and impregnated parts are manufactured.
