EP0660 Thermally Conductive Epoxy Encapsulant

AEROBON AERO-XERM EP0660 is a two-component epoxy encapsulant material designed for electronic applications. It can cures at room temperature or elevated temperature to provide a thermally conductive and flame retardant material.

Product Description

FEATURES AND BENIFITS

Flowable and easy to apply

High bonding to a variety of surface

Good toughness

Thermally conductive

Excellent chemical resistance

Non-flammable

Wide temperature range

OPERATION PROCESS

Mixing and apply: Thoroughly stir each component prior to use. Mix the A and B parts at a 5:1 ratio by weight with manual or automatic mix equipment. Vacuum system is recommended to avoid any air entrapment during the mixing and applying.

Curing: The mixed encapsulant can be cured for 24 hours at room temperature, or for 1 hour at 80°C.

  TYPOCAL APPLICATIONS

  Automotive electronics

  Sensors

SHELF LIFE/STORAGE

Shelf life of each component is one year from date of manufacture when stored at 10-30°C in original unopened container. NYS-XERM EP0660 A part container must be periodically inverted to prevent settling.

After opening, protect each component from excessive moisture by using dry nitrogen as an inert cover.
