產品概覽

LOCTITE AA 332 is a single-component (no-mix) acrylic structural adhesive developed for demanding applications such as bonding surface-permanent magnets (SPM) in electric motors, especially where elevated speed and temperature resistance are required. It cures via a two-step system (activator + adhesive) and achieves fixturing in less than three minutes. Once cured, it delivers durable, high-strength bonds with shear strength around 11 N/mm² while supporting service temperatures up to approximately 180 °C (356 °F).

主要功能與優勢

  • Fast cure (< 3 minutes) — Enables quick assembly turnaround and shorter fixture times.

  • High-temperature performance — Suitable for service up to ~180 °C (356 °F), making it appropriate for thermal cycling environments.

  • High viscosity, thixotropic formula — Maintains position on vertical or intricate assemblies, improves precision.

  • Designed for magnet bonding and metal-to-metal applications — Ideal for securing permanent magnets, motor assemblies, industrial components.

  • Single component adhesive system (with activator) — Simplifies inventory and reduces mixing errors compared to multi-part systems.

申請

  1. 表面處理： Ensure that all bonding surfaces are clean, dry and free of grease or coatings. Remove any loose material.

  2. Activator Application: Apply LOCTITE® activator (such as Activator 7387) to one bonding surface as specified in the TDS.

  3. Adhesive Application: Apply AA 332 adhesive to the mating surface. Use minimal adhesive to fill the bond line; high viscosity ensures controlled flow.

  4. Assembly & Clamping: Press parts together within the recommended time (typically within 2 hours of activator application), and clamp/hold until initial fixture.

  5. Cure & Handling: Allow full cure before applying service loads — typically 24–72 h depending on bond gap, temperature and substrate.

  6. 拆卸／維修： Not intended for frequent disassembly; if required, use recommended methods (heat, mechanical separation) consistent with TDS.

提示：

  • Use in well-ventilated areas and follow safety instructions from SDS.

  • For large bond gaps or unusual materials, consult technical support for suitability.

  • Monitor service temperature and environment, as high temperatures may reduce long-term strength (see heat ageing data).

常見問題

Q1: Can LOCTITE AA 332 be used on plastics or composite parts?
A1: While primarily formulated for metal/metal applications (especially magnet bonding), some plastic substrates may be suitable — however, user verification and trial are advised.
Q2: Is primer required before using this adhesive?
A2: The system uses an activator rather than a traditional primer; follow the manufacturer’s instructions for the correct application of the activator on one bonding surface.
Q3: What is the maximum service temperature?
A3: Up to approximately 180 °C (356 °F) under recommended conditions.
Q4: How quickly does this adhesive set?
A4: Fixturing occurs in under 3 minutes under optimal conditions.
Q5: Can it be used for assemblies requiring disassembly?
A5: This adhesive is designed for durable, mostly permanent structural bonds. For applications needing frequent disassembly, consider a lower-strength adhesive or different technology.
