New formulation has significantly improved reactivity for consistent results during cure cycle
High temperature formula provides negligible shrinkage and strong bond where higher strengths are required between 180-350° F (82-177° C)
Dense, aluminum filled formula is ideal for metal-to-metal bonding, exterior and structural applications
One-part formula requires no mixing
Smooth, high-density paste consistency is easy to dispense where precision bond lines are desired
3M™ Scotch-Weld™ Epoxy Adhesive EC-2214 Hi-Temperature NF (new formulation) has been designed to give you high strength, higher temperature resistance and rigid bond lines. Our high performance adhesive bonds strongly to metals, composites, glass, some plastics. With our NF formula, it cures evenly and consistently for dependable bonding results. The one-part formula requires no mixing.
Combines high mechanical strength with excellent durability
3M™ Scotch-Weld™ Epoxy Adhesive EC-2214 Hi-Temperature NF (new formulation) is a convenient, one-part, heat cured paste that dispenses easily for precise bond lines and negligible shrinkage. It is an aluminum filled, one-part, heat-cure, modified epoxy that we formulated as a thixotropic paste for easy dispensing. When warmed, the adhesive flows smoothly for precise dispensing and neat, clean bond lines. It heat cures between 250-300°F (121-149°C). Using this high temperature formula, high strength bonds are obtained on many metals, glass and some plastics, with negligible shrinkage. It is an ideal choice for metal-to-metal bonding for exterior and structural applications. It can also be used for potting and encapsulating components and for strengthening honeycomb panels and structures. This one-part epoxy is the go-to choice when a void free bond line is required on composite and metal bonding in operating temperatures between 180-350°F (82-177°C).
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.
