LOCTITE AA352 is a modified acrylic adhesive engineered for high-speed bonding, coating, and sealing applications. This advanced formulation cures rapidly under ultraviolet (UV) light exposure. It provides exceptional resistance to both vibration and impact forces. Consequently, LOCTITE AA352 ensures durable and reliable assemblies in demanding industrial environments.
General Information of LOCTITE AA352
LOCTITE AA352 leverages sophisticated modified acrylic technology. It presents as a transparent, light amber liquid with a medium viscosity. This single-component system eliminates the need for pre-mixing, streamlining production processes. Its primary cure mechanism relies on ultraviolet (UV) light radiation at 365nm. This enables rapid fixture times and high throughput.
Furthermore, LOCTITE AA352 offers versatile secondary cure options. Heat curing at 121°C for 30 minutes provides an alternative. Additionally, an activator cure using LOCTITE Activator 7075™ facilitates bonding in shadowed areas. This adaptability makes it suitable for complex geometries and diverse manufacturing setups. The cured material exhibits excellent physical and electrical properties, ensuring long-term performance.
Key Features & Technical Benefits
- Rapid UV Light Cure: Achieves quick tack-free and fixture times, significantly boosting production efficiency. This high-speed curing minimizes work-in-progress and accelerates assembly.
- One-Component System: Requires no mixing or complex preparation, simplifying application and reducing potential errors. This design ensures consistent performance and ease of use.
- High Vibration & Impact Resistance: Forms robust bonds capable of withstanding severe dynamic stresses. This characteristic is crucial for components exposed to harsh operational conditions.
- Versatile Substrate Adhesion: Effectively bonds, coats, or seals a wide range of materials, including metals, glass, and various plastics. This broad compatibility enhances design flexibility.
- Excellent Environmental Resistance: Maintains bond integrity against exposure to motor oil, unleaded gasoline, and varying temperatures. This ensures reliability in diverse operating conditions.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Unitizing electrical devices and sensitive components.
- Assembling appliance parts requiring strong, durable bonds.
- Bonding decorative components where aesthetics and reliability are paramount.
- Sealing and coating metal and glass assemblies for enhanced protection.
