3M™ Scotch-Weld™ Structural Adhesive EC-3439

3M™ Scotch Weld™ Structural Adhesive EC 3439 is an excellent solution for void filling, reinforcing and splicing honeycomb core applications where a high compressive strength and flame retardant compound is required. Our family of epoxy adhesives employs dual strengths; they build handling strength immediately after part assembly and structural strength as they chemically bond to the substrate. Their fast acting strength begins to build as the adhesive cools for rapid, convenient adhesive application with minimal downtime from clamping or fixturing. Their reactive nature achieves dramatically strong bonds to the surface for a durable bond with good temperature and chemical resistance.
