Adhesive

Aircraft adhesives and general-purpose adhesives provide bonding solutions for maintenance, repair, assembly, interior work, and shop applications. BAC offers adhesives from manufacturers including Hardman, Permatex, Gorilla, and other brands for a variety of substrates and bonding requirements.

This selection includes two-part epoxies, instant adhesives, industrial adhesives, and specialty bonding products. Choose the adhesive based on the materials being bonded, required bond strength, cure time, temperature exposure, and intended application.

Adhesives for Aircraft Maintenance and MRO

Different maintenance and repair jobs require different adhesive characteristics. A fast-setting epoxy may be appropriate for a small repair, while another application may require a flexible adhesive, instant adhesive, or specialty bonding product.

Hardman Epoxy Adhesives

BAC carries Hardman epoxy packets in several formulations, including Hardman Red 04001, Hardman Yellow 04002, and Hardman Non-Sag Red 04008.

These products provide convenient two-part epoxy solutions for bonding, filling, patching, tacking, sealing, and related repair applications. Review the individual product information for the specific characteristics and intended uses of each formulation.

General-Purpose and Specialty Adhesives

BAC also offers products such as Permatex 5 Minute Epoxy, Gorilla Glue, Gorilla Wood Glue, and instant adhesive products. These products serve different bonding applications and are not interchangeable simply because they are all classified as adhesives.

For aircraft maintenance, always verify that the selected adhesive is appropriate for the specific component, substrate, and maintenance procedure before application.

Choosing the Right Adhesive

Consider the following when selecting an adhesive:

• Materials: Identify every substrate being bonded.
• Bond strength: Determine the strength and durability required.
• Flexibility: Consider whether the finished bond needs to remain flexible.
• Cure time: Match the adhesive's working and cure characteristics to the repair process.
• Temperature: Verify the product's applicable temperature limitations.
• Gap filling: Determine whether the adhesive is appropriate for the size and type of gap involved.
• Surface preparation: Clean and prepare surfaces according to the adhesive manufacturer's instructions.

Surface Preparation Before Bonding

Proper surface preparation is an important part of adhesive bonding. Surfaces should be prepared according to the adhesive manufacturer's instructions, which may include cleaning, abrasion, degreasing, or other preparation steps.

BAC also carries aircraft abrasives and adhesive removers that may be useful during preparation or removal work, depending on the application.
