UE0730 Flame Retardant Urethane Encapsulant


Aerobon AERO-XERM UE0730 is a two- component urethane material designed for encapsulating or casting applications. It can cures at room temperature to provide a thermally conductive and flame retardant material.

Product Description

FEATURES AND BENIFITS

Room or elevated temperature cure

Low exotherm and stress during cure

High thermal conductivity

Reliable bonding

Easy to mix and apply

Environmentally resistant

Non-flammable

OPERATION PROCESS

Mixing: mix the A and B parts at a 1:1 ratio by volume or 1:1.2 by weight. Handheld cartridges or automatic mix/dispense  equipment should be used to avoid any air entrapment in the  adhesive. Manual mixing is not recommended

Applying: clean the substrates and apply the mixed adhesive, join the parts and add enough pressure until the handling strength is reached.

Curing: the mixed adhesive will reach full cure in 24 hours at  room temperature. Cure can be accelerated elevate temperature  like 80°C for 3 hours.

  TYPOCAL APPLICATIONS

  Battery package assembly

  Power modules

 

SHELF LIFE/STORAGE

Shelf life of each component is six months from date of manufacture  when stored at 10-25°C in original unopened container. After opening, protect each component from excessive moisture by  using dry nitrogen as an inert cover.
