Product Details

JemmTron™ Epoxy Corona Treater Roll Coverings provide a hard, durable surface that is capable of resisting knife cuts and minor operator abuse. This long lasting covering is designed to withstand the rough corona treating conditions, enabling it to endure the heat, ozone and UV generated in a typical corona treating environment. Our proprietary manufacturing method reduces the chance of porosity in the coating, thus preventing pinholes and premature failures.


  • Harder surface than a typical silicone or rubber covering, which provides extra protection
  • Long-lasting to withstand harsh corona treater environment
  • High heat and chemical resistance
  • Easily patched using the affordable JemmTron™ Epoxy Patch Kit
