Handling
This product is supplied in 1’ x 2’ (0.30 m x 0.61 m) sheets in a thickness of approximately 100 mils/2.5 mm and 50 mils/1.25 mm or in roll stock 18 inches wide by 25 lineal feet (45.7 centimeters wide by 7.6 lineal meters), and is ready to use as received. Material should be removed from cold storage and allowed to warm to room temperature before removing the protective packaging. This material has protective liners on it, which must be removed prior to part assembly. The liners will always be a contrasting color from the material to allow the user easy confirmation of removal.
Application
Storage – LOCTITE EF 9899CF AERO requires refrigerated storage. Store 0°F/-18°C or below for maximum storage life. Shelf life 0°F/-18°C or below is 12 months. Store in sealed bag. Allow adequate time for the container to warm to room temperature before opening for use. Ambient temperature shipment of samples will be sufficient for durations of less than 7 days.
Applying – LOCTITE EF 9899CF AERO is a pliable film with tack and drape. It can be cut to any desired shape using ordinary razor knives or scissors. Razor knives using templates as guides work best.
