3M™ Scotch-Weld™ Epoxy Adhesive EC-1469 is a one-part, 100% solids, thermosetting liquid adhesive that provides exceptionally high strength at service temperatures from -70°F to 300°F (-57°C to 149°C). Our pourable adhesive can be applied by a spatula, knife coating, notched trowel, or by extruding into place.

3M™ Scotch-Weld™ Epoxy Adhesive EC-1469 is excellent for bonding a variety of substrates such a metals and many plastics. This cream colored adhesive can be dispensed by knife coating, trowel, roller coating, pump and high pressure injection methods. You can use this high-performance epoxy adhesive to replace mechanical fasteners, screws, rivets and spot welds. Its exceptionally high performance at service temperatures ranging from -70°F to 300°F (-57°C to 149°C) make 3M™ Scotch-Weld™ Epoxy Adhesive EC-1469 the ideal choice for structural applications in the aircraft manufacture and maintenance operations that require performance in high temperatures. Our strong, reliable formula enables curing under minimal pressure sufficient to ensure contact between mating surfaces.

What Are Epoxy Adhesives?
3M™ epoxy adhesives are part of the class of adhesives called "structural adhesives," which also includes polyurethane and acrylic adhesives. Epoxy adhesives are typically formulated with reactive components (Base and Accelerator) that cure when mixed to form a solid plastic material. 3M provides epoxy adhesives in multiple formats to support your processing needs:

Two Part — In this format the Base and Accelerator are stored separately which enables the adhesive to have a long shelf life even when stored at room temperature. These materials are available in a duo-pak cartridges for use with the 3M™ EPX™ Applicator System, enabling you to simultaneously meter, mix and apply two-part adhesives. For larger scale operations, you can purchase these in bulk. Because these parts are mixed at point of use, you can reduce waste by saving non-mixed unused material for a later job.

One Part — In this format, we do the mixing for you and ship it frozen. You store it in a freezer, then remove and thaw it when you're ready to use it.

Adhesive Films — In this one-part format, we not only do the mixing for you, but we also turn it into a film that can be specifically cut to size and placed into your bond line. We offer a variety of films in different weights/thickness and supports. These films must be stored frozen.

In a two-part epoxy adhesive, once the two parts are mixed in their specified ratio, they begin the curing process and offer a limited working time where the adhesive can be applied and the two surfaces positioned as needed. Similarly, in a one-part adhesive there is a limited out time after which material is thawed during which it must be used. This work life or out time lasts anywhere from a few minutes to 48 hours or longer.

In general, epoxy adhesives provide high shear and peel strengths and have good environmental resistance. These adhesives are preferred for their ease of use, mechanical strength and chemical resistance. Depending on the formulation, epoxy adhesives can be flexible or rigid, transparent or opaque, quick setting or slow setting, high flow or low flow, room temperature or elevated temperature cure. Epoxy adhesives are among the strongest adhesives available, making them well-suited for jobs requiring strength and durability.
