Abstract

The invention relates to epoxy resins having an extremely low content of chlorine, particularly a low content of organically bound chlorine. The invention also relates to a production method during which total chlorine contents of less than 100 ppm in the epoxy resin are achieved by extracting solid epoxy resin particles, optionally after a prior comminution and/or reprecipitation. The use of these low-chlorine epoxy resins in the fields of electronics and/or electrical engineering considerably reduces the components' susceptibility to corrosion.
