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.
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. |
