Product Description
LOCTITE® 416™ is a one-component, high-viscosity ethyl cyanoacrylate instant adhesive formulated for general-purpose bonding of plastics, rubbers and metals. The transparent adhesive delivers rapid fixture times through moisture-activated curing and develops high bond strength on a wide range of substrates. Its higher viscosity enables better control during application while maintaining the fast-curing performance expected from cyanoacrylate technology. LOCTITE 416 also meets the lot requirements of Military Specification Mil-A-46050C and is qualified to Commercial Item Description A-A-3097, making it suitable for industrial assembly, maintenance and repair applications.
Key Features & Benefits
- High-viscosity ethyl cyanoacrylate formulation.
- One-component adhesive requiring no mixing.
