Product Introduction
3M™ Scotch-Weld™ Structural Adhesive EC-3964 is a sprayable solution version of 3M™ Structural Adhesive Film AF 147, engineered for bonding screen-in-sound suppression panels on aircraft engine nacelles. This structural adhesive offers high bond strength across a wide temperature range from -67°F to 300°F (-55°C to 150°C), making it suitable for use in demanding aerospace environments and challenging design configurations.
Designed for a 350°F (175°C) cure, 3M™ Scotch-Weld™ Structural Adhesive EC-3964 can be applied by spraying directly onto screens without filling holes, offering efficiency and ease of use. It demonstrates outstanding bonding performance for metal-to-metal and metal-to-honeycomb structures. Once cured, it delivers strong, durable bonds with excellent environmental resistance.
