Main features

  • Very-Low-Viscosity Precision Bonding
  • Fast Mixed-Material Fixturing
  • Heat-Conditioned Bond Strength

Product Description

LOCTITE 4014 is a one-part, very-low-viscosity cyanoacrylate instant adhesive for fast room-temperature bonding of plastics and metals. The transparent, colorless-to-slightly-yellow liquid requires no mixing and cures with atmospheric moisture. Depending on the substrate pair, fixture times range from 5 to 30 seconds for many stainless-steel, ABS, polycarbonate, polyurethane, and G-10 epoxy combinations, while PVC-to-PVC fixtures in 60 to 80 seconds. After 24 hours at 22 deg C, the cured adhesive reaches Shore hardness 65 and 28 N/mm^2 tensile strength. It is also intended for disposable medical-device assembly within the product-specific evaluation scope.

Key features

  • Very-Low-Viscosity Flow: A 1 to 5 mPa s viscosity suits thin, close-fitting plastic and metal joints.
  • Fast Mixed-Material Fixture: Many stainless-steel-to-plastic combinations fixture in 5 to 10 seconds.
  • Heat-Conditioned Strength: Grit-blasted steel lap shear remains at least 12 N/mm^2 after a 24-hour, 121 deg C heat condition.

Applications / Suitable for

  • Fast bonding of plastics and metals
  • Stainless-steel-to-plastic assembly
  • Disposable medical-device assembly

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
1 to 4 mPa.s
Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
