Highlights
- Low density < 0.7 g/cc for substantial weight reduction
- Fast cure and gel-time at room temperature yields higher manufacturing throughput
- High-torque resistance ideal for insert potting application
- Pumpable with automated dispensing equipment
- Non-sag (thixotropic) enable vertical edge close-out and panel forming
- Flame Retardant per FAA 14CFR 25.853 (a)
3M™ Scotch-Weld™ Epoxy Adhesive EC-3542 B/A FR is a two-component, flame retardant epoxy adhesive that cures at room temperature to form impact-resistant structural bonds. It offers a lightweight, fast-curing adhesive for general potting, edge fill and honeycomb panel forming to meet unique manufacturing requirements.
A two-part epoxy potting compound with fast gel and cure time at room temperature
Consistent flow enables fast pumping and application through pneumatic dispensers and automated mixing and dispensing equipment. After application and cure, EC-3542 forms tough, impact-resistant structural bonds. It also offers high torque resistance with high compressive strength, making it ideal for insert potting application.
