  • Documented A-A-3097 Qualification

Product Description

LOCTITE® 444™ is a one-component, medium-viscosity ethyl cyanoacrylate adhesive specifically formulated for electronics assembly applications. It provides rapid room-temperature curing through reaction with atmospheric moisture and is designed for use with LOCTITE® TAK PAK® accelerators to achieve instant fixturing when required. The adhesive bonds plastics, rubbers and metals, making it suitable for wire tacking, tamper-proofing adjustable components, attaching edge guides and mounting standoffs or stiffeners onto circuit boards. Its medium viscosity ensures controlled application while delivering strong, reliable bonding performance in demanding electronic manufacturing environments.

Key Features & Benefits

  • Single-component adhesive requiring no mixing.
  • Fast moisture-cure cyanoacrylate technology.
  • Medium viscosity enables controlled dispensing and positioning.
  • Compatible with LOCTITE® TAK PAK® accelerators for instant cure.
  • Bonds plastics, rubbers and metals.
  • Designed for electronics manufacturing applications.
  • Qualified to Commercial Item Description A-A-3097.

Recommended Applications

  • Wire tacking to coil forms.
  • Tamper-proofing adjustable electronic components.
  • Mounting standoffs and edge guides on circuit boards.
  • Attaching stiffeners to printed circuit boards.
  • General bonding of plastics, metals and elastomers.

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
