Loctite EA 9323

LOCTITE EA 9323 AERO (Hysol EA 9323) is a two-component paste adhesive that is low in viscosity, possesses some toughness and maintains high temperature strength. Its room temperature cure capability makes it suitable for the repair of metal and composite structures, including laminating and injection. It has no metallic fillers. Its service temperature is 121 °C.
