3M Adhesives

3M adhesives provide bonding solutions for aircraft maintenance, repair, interior work, component assembly, and other MRO applications. BAC carries a selection of 3M adhesive products including Scotch-Weld structural epoxies, neoprene and rubber-based adhesives, contact adhesives, spray adhesives, and specialty bonding products.

3M offers adhesive formulations for different substrates, bond strengths, cure characteristics, temperatures, and application methods. Select the adhesive based on the materials being bonded and the requirements of the specific maintenance or repair application.

3M Adhesives for Aircraft Maintenance

Aircraft maintenance frequently requires adhesives for bonding, assembly, gasket installation, interior repairs, insulation and material attachment, and other specialized applications. 3M adhesive products are available in several formulations so technicians can select a product appropriate for the intended use.

3M Scotch-Weld Epoxy Adhesives

3M Scotch-Weld two-part epoxy adhesives are available in several formulations for demanding bonding applications. BAC carries products including DP100, DP110, DP420, and DP460. These adhesives are supplied in different cartridge configurations and may require a compatible 3M EPX dispenser and mixing nozzle.

Because epoxy performance varies by formulation, review the individual product information and current 3M technical documentation before selecting an adhesive for a specific aircraft application.

3M Neoprene and Contact Adhesives

3M 1300 and 1300L are synthetic rubber-based adhesives used for compatible rubber and gasket bonding applications. 3M 1357 is a solvent-based contact adhesive intended for general-purpose high-strength bonding applications.

These products have different application characteristics, substrates, and service requirements. Always verify compatibility with the materials being bonded and follow the manufacturer's application instructions.

Choosing a 3M Adhesive

Before selecting a 3M adhesive, consider:

• Substrate: Identify the materials being bonded and verify adhesive compatibility.
• Bond requirements: Consider the required strength, flexibility, and durability.
• Temperature: Verify the adhesive's applicable service-temperature range.
• Cure or set time: Select a product that fits the required assembly process.
• Application method: Determine whether the product is brushed, sprayed, or dispensed from a cartridge.
• Mixing requirements: Two-part adhesives may require a compatible dispenser and mixing nozzle.
• Aircraft requirements: Verify that the adhesive is appropriate for the specific aircraft/component application.

3M Adhesive Accessories

Some two-part 3M Scotch-Weld adhesives require dedicated dispensing equipment and mixing nozzles. BAC also carries 3M Scotch-Weld mixing nozzles for compatible adhesive cartridges.

Using the correct dispenser and mixing nozzle helps provide the intended mixing ratio and controlled application specified by the adhesive manufacturer.
