Visiomer® Specialty Methacrylates for Electrical Insulation Resins

Evonik’s specialty methacrylate monomers are widely used as reactive diluents in unsaturated polyester (UP) and polyester imide (PEI) based insulation resins. The usage of styrene as a reactive diluent for UP and PEI resins has recently come under increased environmental and regulatory scrutiny. 

Electrical insulation resins, also known as impregnation resins, are used to protect electric motors, generators, and transformers from moisture, heat, and physical damage.
