LOCTITE 454

Main features

  • Thixotropic Application Control
  • High-Strength Structural Bonding
  • Moisture-Cure Bonding Processing

Product Description

LOCTITE® 454™ is a one-component, high-viscosity thixotropic ethyl cyanoacrylate adhesive designed for bonding difficult-to-bond materials requiring uniform stress distribution and strong tensile and shear strength. Its gel consistency prevents running and dripping, making it ideal for vertical and overhead applications. The adhesive rapidly bonds metals, plastics and elastomers, while also performing well on porous substrates such as wood, paper, leather and fabric. LOCTITE 454 cures in the presence of atmospheric moisture and develops high strength with excellent environmental resistance.

Key Features & Benefits

  • Thixotropic gel formulation prevents adhesive flow and dripping.
  • High-strength bonding for metals, plastics and elastomers.
  • Suitable for porous materials including wood, paper, leather and fabric.
  • One-part adhesive requiring no mixing.
  • Rapid moisture-cure cyanoacrylate technology.
  • Good tensile, shear and environmental resistance properties.
  • Effective on vertical and overhead bonding applications.

Recommended Applications

  • Bonding difficult-to-bond substrates requiring stress distribution.
  • Vertical and overhead assembly applications.
  • Metal, plastic and elastomer assembly.
  • Wood, paper, leather and fabric bonding.
  • General industrial maintenance and repair operations.

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
