EC-3524 B/A offers a unique combination of easy “dispense-ability” and non-sag performance, resulting in a number of productivity-enhancing advantages.

Fast, Direct Application
EC-3524 B/A can be hand-mixed. It reduces or eliminates hand troweling and trapped air that helps eliminate pinholes, voids and porosity. EC-3524 B/A is ideal for filling edges in honeycomb sandwich construction for galleys, luggage bins, partition walls, lavatories, seating, ceiling panels, floorboards and passenger doors.

Fast-Cure, Non-Brittle, Non-Sag Material
EC-3524 B/A is easier to handle and resists chip-outs and breakouts when cured. Its non-sag property allows application to multiple work pieces at one time. In addition, this compound exhibits good paint retention and adhesive bond strength.

Ready to Sand
At a room temperature of 75°F (24°C), this compound is sandable within 3 hours of mixing to keep processes moving forward. It costs less to store and can be closer to the work when needed. In aircraft manufacture and MRO, time is money so we made EC-3524 B/A fast and easy to use. Our shelf-stable formula requires no freezer storage.
