LOCTITE® AA A-671 Structural Adhesive
Features and Benefits
LOCTITE AA A-671 is a dark green, 2-part, toughened, external mixing thixotropic structural acrylic adhesive used for magnet bonding.
LOCTITE® AA A-671 is a 2-part structural adhesive for super fast fixture and ease of use thanks to external mixing application. It is non-flammable, 100% solids and has lower odor compared to other acrylic adhesives. Specifically designed for the bonding of magnets, it is used in permanent magnet brushes in DC motors, speaker assemblies, generators and magnetic assemblies.
- Super fast fixture time of 75 seconds
- External mixing application allows high production throughput and accommodates off-ratio mixing
- Designed for Surface Permanent Magnet (SPM) Bonding
- High impact resistance and good humidity resistance
- Non-flammable, 100% solids and has lower odor
