Product Description

LOCTITE® 415™ is a one-component, high-viscosity methyl cyanoacrylate adhesive formulated for general-purpose instant bonding of metals, plastics and elastomers. It is particularly well suited for metal bonding applications and delivers rapid fixture speeds through moisture-activated curing. The adhesive provides strong structural performance, excellent environmental resistance, and reliable bonding on a wide range of substrates. LOCTITE 415 complies with Military Specification Mil-A-46050C and Commercial Item Description A-A-3097, making it suitable for demanding industrial and maintenance applications.

  • High-viscosity methyl cyanoacrylate adhesive.
  • Excellent bonding performance on metal substrates.
  • One-component formulation requiring no mixing.
  • Fast humidity-activated room-temperature cure.
  • Bonds metals, rubbers and plastics.
  • Qualified to Mil-A-46050C and A-A-3097 specifications.
  • Strong chemical and environmental resistance after cure.

Recommended Applications

  • Metal component assembly and bonding.
  • Rubber and plastic bonding applications.
  • Industrial manufacturing and maintenance repair.
  • General-purpose instant adhesive applications.
  • High-strength precision assemblies.

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
