UE120 Urethane Encapsulant


Aerobon AERO-XEAL UE120 is a two-component urethane material designed for encapsulating or casting applications. It has ultra low viscosity and can cures at room temperature to provide a flame retardant material.

Product Description

FEATURES AND BENIFITS

Low viscosity and excellent flowability

Room temperature curable

Low hardness and stress during cure

Resistant to enviriomental test

Non-flammable

OPERATION PROCESS

Mixing and apply: Mix the A and B sides 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 initially cured for 24 hours at room temperature, or for  3-4 hours at 60°C. Complete curing will be achieved after 7 days at room temperature. 

  TYPICAL APPLICATIONS

  Autmotive electronics

  Battery assembly

  Power modules

SHELF LIFE/STORAGE

Shelf life of each component is 6 months from date of manufacture when stored at 25°C in original unopened container. After opening, protect each component from excessive moisture by using dry nitrogen as an inert cover.
