UE0730LV Urethane Encapsulant


AEROBON AERO-XERM UE0730LV is a two-component urethane encapsulant designed for electronic applications. It can cures at room temperature to provide a thermally conductive and flame retardant material.

Product Description

FEATURES AND BENIFITS

Low exotherm and stress during cure

Low viscosity and excellent flowability

Room temperature cure

Thermally conductive

Environmentally resistant

Non-flammable

Wide application temperature range

OPERATION PROCESS

Mixing and apply: Thoroughly stir each component prior to use. 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 4-5 hours at 60°C. Complete curing will be achieved after 7-8 days at room temperature.

  TYPICAL APPLICATIONS

  On board charger

  Battery assembly

  Power modules

SHELF LIFE/STORAGE

Shelf life of each component is 6 months from date of manufacture when stored at 10-25°C in original unopened container. NYS-XERM UE0730LV A side container must be periodically inverted to prevent settling.

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