Features and Benefits
slide 1 of 1
A 1-part, medium-viscosity, UV acrylic, light-cure adhesive for potting, sealing and bonding thermoplastics, glass and metals.
LOCTITE® AA 3974 is a translucent-colorless, medium-viscosity, UV acrylic-based, light-cure adhesive for potting, sealing and bonding thermoplastics, glass and metals. When exposed to sufficient UV and/or visible light, it cures rapidly to form a robust bond that stands up to heavy thermal cycling and harsh environmental conditions. This makes it highly relevant for use in the medical device industry to assemble disposable devices.
