Product Description
LOCTITE® AA 312™ is a one-component modified acrylic ester adhesive formulated for bonding dissimilar materials, including metals, glass, and ceramics. Used with LOCTITE® Activator 736™ or 734™, the adhesive cures at room temperature and provides rapid fixture times for close-fitting assemblies. Its medium-viscosity formulation requires no mixing, making it suitable for manufacturing and industrial bonding applications where fast processing and reliable bond development are required.
Key features
- One-component formulation: Requires no mixing, simplifying application and assembly processes.
- Room-temperature cure: Cures with LOCTITE® Activator 736™ or 734™ to support rapid fixture times.
- Dissimilar material bonding: Suitable for bonding metals, glass, and ceramics in close-fitting assemblies.
Applications / Suitable for
- Metal-to-metal bonding
- Glass bonding applications
- Ceramic assembly applications
- Industrial manufacturing and assembly operations
- Close-fitting bonded joints requiring fast fixturing
