- High Peel Strength
Product Description
LOCTITE® 411™ is a one-component, high-viscosity ethyl cyanoacrylate adhesive gel designed for gap-filling applications involving rubbers, plastics and metals. The adhesive combines excellent peel strength with enhanced heat resistance while maintaining the rapid curing characteristics typical of cyanoacrylates. Its gel consistency prevents migration after application, allowing precise placement on vertical and irregular surfaces. LOCTITE 411 cures rapidly in the presence of atmospheric moisture and develops strong bonds across a wide range of substrates, making it suitable for industrial assembly, repair and maintenance applications.
Key Features & Benefits
- High-viscosity gel formulation with gap-filling capability.
- Excellent peel strength compared with standard instant adhesives.
- Enhanced heat resistance for demanding environments.
- One-component adhesive requiring no mixing.
- Fast humidity-activated cure at room temperature.
- Suitable for bonding rubbers, plastics and metals.
- Controlled non-sag application on vertical surfaces.
Recommended Applications
- Gap-filling bonding applications.
- Rubber-to-metal and plastic-to-metal assemblies.
- General industrial assembly and maintenance.
- Applications requiring improved peel strength.
- Elevated-temperature bonding environments.
