Main features

  • Passive-Surface Cure Acceleration
  • Very-Low-Viscosity Surface Wetting
  • 30-Minute On-Part Activity

Product Description

LOCTITE SF 736 is a light-amber, very-low-viscosity activator for accelerating cure of anaerobic structural adhesives and sealants. The aldehyde-amine condensate and organocopper active system is carried in trichloroethylene and isopropanol. It is applied to passive metals, inert surfaces, or assemblies with larger gaps where the anaerobic process needs activation. A viscosity of 3 mPa s supports rapid surface wetting. The treated surface remains active for up to 30 minutes, allowing adhesive application within a defined process window.

Key features

  • Passive-surface cure acceleration: The activator supports anaerobic adhesive and sealant cure on passive metals and inert surfaces.
  • Very-low-viscosity wetting: A viscosity of 3 mPa s supports rapid application over prepared surfaces.
  • 30-minute on-part activity: The treated surface remains active for up to 30 minutes under the listed condition.

Applications / Suitable for

  • Activating passive metal surfaces
  • Accelerating anaerobic structural adhesives
  • Accelerating anaerobic sealants or larger-gap 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
