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.

3M™ Scotch-Weld™ Epoxy Adhesive EC-3542 B/A FR is a unique adhesive formulation with low density, high torque strength and fast cure time.
A two-part epoxy potting compound with fast gel and cure time at room temperature
3M™ Scotch-Weld™ Epoxy Adhesive EC-3542 B/A FR is a unique adhesive formulation with low density, high torque strength and fast cure time. Using 3M glass bubble technology, this product is half the weight of traditional structural bonding adhesives for an excellent strength-to-weight ratio. The result: a product that can help substantially reduce weight in aircraft interior structures with a density of <0.7g/cc.

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.

Fast Cure at Room Temperature
In aerospace manufacturing and aircraft maintenance, time is money. This adhesive delivers fast flow for quick application process with minimal prep time. Once applied, 3M™ Scotch-Weld™ Epoxy Adhesive EC-3542 B/A FR cures quickly at room temperature. The non-sag formula can be used in vertical applications without running, dripping or sagging. In addition, the thixotropic formula enables vertical edge close-out and panel forming.
