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.
|
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. |
