Zepoxy RER 527 EL
Zepoxy RER 527 EL is a standard liquid epoxy resin recommended for use with hardener Zepoxy REH 416 in high voltage heat-curing electrical castings for manufacturing of different types of transformers. The principal feature of this resin is its low hydrolysable chlorine content. This resin provides good pigment wetting and good resistance to filler settling, and a high level of mechanical and chemical resistance properties in cured state.
