CHT Group EP EF EPI Engineered Polymers Extra Flex Polyurea
Categories: Polymer; Thermoset
Material Notes: EP EF, Extra Flex Polyurea, “Powered by Reactamine® Technology, is a two component 100% solid Polyurea, with superior performance in industrial applications. EP EF displays extremely fast cure times with excellent adhesions to different substrates. EP EF can be spray applied at temperatures ranging from 20°F to 150°F. EP EF has excellent chemical and water resistance. EP EF has a temperature range of -40°F to 350°F. EP EF conforms to USDA and FDA guidelines for incidental food contact.

Applications: EP EF adheres well to several substrates including concrete, steel, and wood. Some typical uses include:

  • SECONDARY CONTAINMENT
  • WASTEWATER LAGOON AND POOL LININGS
  • TABLE EDGING
  • COLD STORAGE AREAS
  • WASH BAY AND SHOWER LININGS
  • COOLING TOWERS
  • PETROCHEMICAL REFINERIES
  • OILFIELD PIPELINE COATINGS
  • WATER PROOFING
  • SEWER LINERS
  • MANHOLE RESTORATION
  • INDUSTRIAL FLOORING
  • BRIDGE COATINGS

    • Part of the Amber Chemical Group. Data provided by manufacturer.
