Product Description
LOCTITE® AA 330 is a one-component, high-viscosity, activator-cured acrylic adhesive for general-purpose bonding of metal, wood, ferrite, ceramic, and plastic materials. The slightly cloudy, colorless-to-pale-yellow liquid requires no mixing and is commonly used for tool handles, appliances, sporting goods, and decorative trim. Under specified test conditions, it develops high lap-shear and tensile strength on grit-blasted mild steel and supports bond gaps up to 0.5 mm when used with LOCTITE Activator 7387 or 7386.
Key features
- Multi-material bonding: Suitable for bonding metals, wood, ferrite, ceramics, and compatible plastics.
- One-component application: Requires no adhesive mixing and cures rapidly when paired with the specified activator.
- High-strength, gap-tolerant performance: Provides 15–30 N/mm² lap-shear strength on grit-blasted mild steel and supports gaps up to 0.5 mm under specified application conditions.
