LOCTITE 455

Main features

  • Low-Odor Bonding Processing
  • Gel-Consistency Bonding Placement
  • Low-Blooming Bonding Cure

Product Description

LOCTITE® 455™ is a one-component, high-viscosity alkoxyethyl cyanoacrylate adhesive gel engineered for general-purpose bonding applications requiring low odor and low blooming characteristics. The gel consistency prevents running or dripping, making it particularly suitable for vertical and overhead applications where adhesive control is critical. LOCTITE 455 rapidly cures in the presence of atmospheric moisture and bonds a wide range of substrates including metals, plastics and elastomers. Its low vapor emissions make it especially useful in applications where conventional cyanoacrylate vapors may be undesirable.

Key Features & Benefits

  • Low odor formulation for improved operator comfort.
  • Low blooming characteristics minimize cosmetic residue.
  • Gel consistency prevents running and dripping on vertical surfaces.
  • One-component adhesive requiring no mixing.
  • Bonds metals, plastics and elastomers.
  • Humidity-cure technology for rapid room-temperature curing.
  • Suitable where vapor control is difficult.

Recommended Applications

  • General-purpose industrial bonding.
  • Vertical and overhead assembly operations.
  • Bonding plastics, metals and elastomers.
  • Applications requiring low odor and low blooming performance.
  • Maintenance, repair and production assembly processes.

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
