3M™ Scotch-Weld™ Epoxy Adhesive 2290 is a solvent-based, low viscosity amber tinted thermosetting epoxy adhesive requiring heat cure. It is designed for metal to metal coating and subsequent bonding: for example, in motor lamination and wire winding.

  • Offers exceptionally high shear and peel strength
  • Solvent based low viscosity coating formulation
  • Dries to a tack-free film which allows bonds to be made up to 3 months later for B-staging and multi-stage processes
  • Excellent wetting during cure requires only coating a single surface
  • Heat press during cure recommended for lamination use

PRODUCT FAQ

  1. What is 3M™ Scotch-Weld™ Epoxy Adhesive/Coating 2290?

    3M™ Scotch-Weld™ Epoxy Adhesive/Coating 2290 is a two-part epoxy that cures at room temperature and provides excellent environmental resistance.

  2. What kind of surfaces does it bond with?

    It bonds well to many surfaces such as metals, ceramics, wood, concrete and most plastics.

  3. Can I use this adhesive for outdoor projects?

    Absolutely! Its chemical resistance makes it an excellent choice for outdoor applications or environments where harsh chemicals are present.

  4. How long does the curing process take?

    This epoxy typically reaches handling strength in approximately one hour and can be machined or painted after three days. Full cure is reached in five to seven days depending on the ambient conditions.

  5. Are there any safety precautions that I need to consider before using this product?

    The material should not be used without appropriate health monitoring and controls. Consult the applicable Safety Data Sheet (SDS) before using this product.

Offers Exceptionally High Shear and Peel Strength

3M™ Scotch-Weld™ Epoxy Adhesive 2290 is designed to coat and bond metal substrates, including steel and aluminum. This epoxy is a low (21% solids) formulation with very low viscosity. 3M™ Scotch-Weld™ Epoxy Adhesive 2290 can be applied in a variety of methods including: brushing, flow coating, dip coating, roll coating, knife coating and spraying. It is ideal for assembling metal laminations and various applications on metal cores, rotors and motors and wire windings. B-staging coated and dried parts are optional; allowing final cure up to 3 months later.

Recommended Applications
  • Assemble laminated steel cores for electrical motor stators and rotors
  • Adhere copper foil to B-staged epoxy in the manufacture of printed circuits
  • Coat, protect and utilize coils and electronic subassemblies
  • Thin metal stack laminations such as those used in magnetic tape heads
Understanding Epoxy Adhesives

Epoxy adhesives are part of the class of adhesives called "structural adhesives," which include polyurethane, acrylic, cyanoacrylate and others. One-part heat cured epoxies are rigid adhesives that have outstanding strength when measured at elevated temperatures. These adhesives require a thermal cure, typically around 250°;-350°F (120°;-180°C) for 40-60 minutes, to achieve full strength. They provide high shear and peel strengths, depending on the formula, and better heat and chemical resistance than other common adhesives.

Epoxy adhesive (often referred to as epoxy glue) is widely used in building and home construction; aircraft and automobile manufacturing; bicycle, boat, golf clubs, ski and snowboard assembly as well as a host of home use and other applications. It is used virtually anywhere high-strength bonds are needed along with resistance to environmental conditions. These adhesives are popular for their ease of use, mechanical strength and chemical resistance. Formulations can be created to make epoxy for plastic flexible or epoxy for metal rigid, epoxy resin transparent or opaque, quick setting or slow setting. The versatility with which these adhesives can be formulated helps meet almost any requirement for bonding wood, metal, glass, stone and various plastics.
