LOCTITE 411

Main features

  • High-Viscosity Cyanoacrylate Gel
  • Controlled Non-Sag Application
  • 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.

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application
