3M Scotch-Weld Epoxies | McMaster-Carr

To allow time to adjust and position parts, these epoxies remain workable for at least 90 minutes. The strongest and most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals.

The size listed is the combined total of the two parts. Use cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.

2158 bonds to damp concrete.

Toughened Epoxy Structural Adhesives

Toughened adhesives are blended with rubber particles for better impact resistance than standard epoxies. They form flexible, resilient bonds. The most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals. Choose an adhesive that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.

The size listed is the combined total of the two parts. Use with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.

DP420NS, DP460NS, E-40HT, and 9462 are nonsagging, so they won't drip from vertical or overhead surfaces.

Mixer Nozzles for Two-Part Adhesive Cartridges

Taper Tip

Step Tip

Bell-Mount Connection

Twist-Lock Connection

To simultaneously mix and dispense two-part adhesives, attach these mixer nozzles to a dual cartridge. Mixing elements help combine the two parts of an adhesive as it flows through the nozzle. A short nozzle with many mixing elements combines adhesive while minimizing the adhesive left in the nozzle after dispensing. Choose a nozzle that matches the connection type, size, and mix ratio of your adhesive cartridge.

A step tip allows you to trim the opening to the diameter you need.

Epoxy Potting Compounds

Encase electronic assemblies in a layer of epoxy for protection from dust, chemicals, moisture, mechanical shock, and vibration. The strongest of the potting compounds, epoxies are rigid and wear resistant. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. All require a mixer nozzle and gun to dispense.

3M DP460EG and DP4XLEG also require a plunger to dispense.
