ET3201 – Two-part Epoxy for Electronic Devices

ET3201 is two-component epoxy which exhibits low viscosity, easy to handle, excellent chemical resistance and perfect surface gloss. This product is suitable for various applications in electronics, such as potting, casting, sealing, encapsulating and bonding. ET3201 is ideally used for general purpose which require long work life.

Features and benefits

  • The hardener of ET3201 will not yield an insoluble & whitish solid
  • When exposing to air.
  • The curing surface will not oilly and poor gloss
  • Excellent insulation properties even under high humidity
  • Long working time of ~ 8 hours
  • Excellent chemical and solvent resistance
  • Comply to the 2011/65/EU RoHS regulations
