Feature of epoxy for electronics

  • This product is a heat curing type, has a good temperature resistance, low total chlorine.
  • Need to heat curing, and needs low temperature (below 10 ℃).
  • After curing, it has strong toughness, high bonding strength at the bonding site, impact resistance, and shock resistance.
  • The cured product has good acid and alkali resistance, moisture proof, waterproof, oil proof and dustproof performance, heat resistance and atmospheric aging.
  • The cured product has good electrical and physical properties such as good insulation, compressive strength, and bonding strength.

Using process:

Bonded parts need to be kept dry and clean, When using epoxy adhesive, it takes 1-1.5 hours to warm up after taking it out of the oven, and it takes 30 minutes to cure it after being dispensed into a 150℃ oven.

During the curing process, if the amount of glue applied is too much or the temperature is too high, yellowing may occur. In such cases, reduce the curing temperature appropriately.

Precautions of epoxy for electronics

  • Because the product is heated reacts to chemical products, so the effect of environmental temperature on the product quality is very big, please send the product stored in low temperature environment, in order to ensure the stability of the product and quality. After taking out the unused colloid, please cover it tightly and put it back into the frozen environment.
  • Few people contact adhesive solution for a long time will produce mild skin irritation, itch had mild pain, it is recommended to use when wear protective gloves, please with skin with acetone or alcohol wipe, and use cleaner clean.
  • Before using it in large quantities, please try it out in small quantities and master the skills of using the product so as to avoid mistakes.




Storage and transportation of epoxy for electronics
