LOCTITE AA 330 Structural Adhesive for Metal, Plastic, Wood, Ceramic and Ferrite Bonding

Category: Brand:
LOCTITE AA 330 Structural Adhesive is a high-viscosity, one-component acrylic bonder designed for strong assembly of metal, wood, ferrite, ceramic, and compatible plastic materials. Although supplied as a no-mix adhesive, it cures through a two-step process with LOCTITE SF 7387 or SF 7386 Activator. This practical system delivers dependable structural strength, controlled non-sag application, and good impact resistance for manufacturers, maintenance teams, and professional repair operations.

LOCTITE AA 330 Structural Adhesive Benefits

LOCTITE AA 330 Structural Adhesive simplifies production because the adhesive itself requires no resin-to-hardener mixing. Operators apply activator to one prepared surface and adhesive to the other, then assemble the parts within the recommended working window. This approach reduces proportioning errors, supports cleaner workstations, and makes the product suitable for manual dispensing, repair work, and repeatable industrial assembly.

The medium-to-high viscosity, thixotropic formula helps the material remain where it is dispensed. It can form controlled beads on horizontal, vertical, and irregular surfaces without excessive running. This characteristic is useful when bonding tool handles, appliance components, sporting goods, decorative trim, and mixed-material parts that need accurate placement before fixturing.

Multi-Substrate Applications for LOCTITE AA 330 Structural Adhesive

The adhesive is formulated for bonding metals, wood, ferrites, ceramics, and rigid plastics. It is especially valuable for joining dissimilar substrates such as PVC, phenolic compounds, and acrylic materials. Typical applications include metal inserts in plastic parts, equipment handles, appliance panels, decorative components, magnetic assemblies, brackets, housings, and general industrial products.

LOCTITE AA 330 Structural Adhesive offers good impact resistance, helping bonded assemblies withstand handling, vibration, and mechanical shock. The service temperature range extends from approximately -25°C to 100°C, making the product suitable for many indoor and industrial environments. Users should validate every combination of substrate, coating, joint geometry, and operating condition before full production.

Typical Technical Performance

The uncured adhesive is a slightly cloudy, colorless-to-pale-yellow liquid based on urethane methacrylate ester chemistry. Typical specific gravity is approximately 1.05 at 25°C, while Brookfield viscosity ranges from 45,000 to 90,000 mPa·s. With LOCTITE SF 7387 applied to one surface, fixture time is typically about three minutes under Henkel test conditions.

After curing for 24 hours at 22°C, published lap-shear strength on grit-blasted mild steel ranges from 15 to 30 N/mm². Typical tensile strength on similarly prepared mild steel ranges from 12 to 22 N/mm². These values are reference data rather than guaranteed purchasing specifications and may vary with surface preparation, activator coverage, bond gap, temperature, and cure time.

How to Apply LOCTITE AA 330 Structural Adhesive

Clean all bonding surfaces and remove oil, grease, dust, oxidation, moisture, and loose contamination. Apply LOCTITE SF 7387 or SF 7386 Activator to one surface and allow the solvent carrier to evaporate. Apply the adhesive to the opposite surface, assemble the parts within 15 minutes, and clamp the joint until sufficient fixture strength develops.

The recommended bond-line gap is approximately 0.1 mm. For gaps up to 0.5 mm or when faster curing is required, apply activator to both surfaces and assemble within one minute. Remove excess uncured adhesive with a suitable organic solvent. Allow 24 to 72 hours for full strength before applying demanding service loads.
