ES3401 Epoxy Adhesi for Electronics Devices

ES3401 is a one component epoxy adhesive for the application of electronic devices. This resin develops tough, strong, structural bonds which provide excellent shear, peel, and impact strength. This resin can be applied to the encapsulation of electronic products. The durability of this product is high level and this resin can pass many environmental test experiments.

Features and benefits

  • This product is solvent-free, non-volatile, which offers excellent protection and vibration resistance for electronic devices.
  • This product has excellent dimensional stability over a wide temperature range.
  • This resin offers excellent retention of electrical insulation properties under high humidity conditions. It is also effective against moisture and water and still remain the excellent retained strength o after environmental test experiments.
  • Comply to the 2011/65/EU RoHS regulations
  • Comply to Chlorine < 900ppm, Bromine < 900ppm, Chlorine + Bromine < 1500 ppm
