Simple Application Instructions

1. Clean: For optimal results, ensure all bond surfaces are completely clean and free from grease, oil, or previous contaminants. If using aqueous washing systems, check compatibility beforehand.
2. Apply: To ensure a fast and reliable cure, apply LOCTITE SF 7649 Activator to one of the bond surfaces and the LOCTITE AA 326 adhesive to the other surface. For larger gaps (up to 0.5 mm) or maximum cure speed, apply the activator to both surfaces.
3. Assemble: Assemble the parts quickly. Parts treated with activator on a single side should be joined within 15 minutes; if both sides are activated, assemble immediately within 1 minute. Hold or clamp the bond until it achieves fixture strength. Allow 24 to 72 hours for full strength development.

Frequently Asked Questions (FAQ)

What is LOCTITE AA 326 used for?

LOCTITE AA 326 is a high-strength structural adhesive designed primarily for magnet and structural bonding. It is specifically formulated to prevent component shifting and bond failure in electric motors, loudspeaker hardware, and jewelry due to high vibration and mechanical shocks.

Can LOCTITE AA 326 be disassembled?

No, it creates a permanent structural bond. Because it is highly resistant to chemicals and temperatures up to +120°C, intentional disassembly requires specialized mechanical grinding, aggressive scraping, or the use of heavy organic solvents to clean away the cured anaerobic matrix.

Does LOCTITE AA 326 work on plastics?

Generally, no. This product is not normally recommended for use on plastic substrates—particularly thermoplastic materials—as it could result in stress cracking of the plastic. It is highly effective on rigid metal substrates, ferrites, and plated components.

Is LOCTITE AA 326 safe for all environments?

LOCTITE AA 326 is manufactured under strict Henkel LMS quality standards. However, it is not recommended for use in pure oxygen and/or oxygen-rich systems, and should never be selected as a sealant for chlorine, active chemical streams, or other strong oxidizing materials.
