LOCTITE SF712
Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium
Main features
- Loctite SF712 | Cyanoacrylate Adhesive Activator
- Fast Assembly Fixturing
- Low-Viscosity Bonding Flow
Product Description
LOCTITE® SF 712™ is a cyanoacrylate adhesive activator formulated to significantly increase the cure speed and fixture speed of LOCTITE® instant adhesives. The activator can be applied either before or after adhesive application and is particularly effective for rapid fixturing, difficult substrates, and production environments requiring fast handling strength. It is widely used for securing wires and coils to printed circuit boards, tamper-proofing adjustable components, and mounting stand-offs, edge guides, and board stiffeners.
Key Features & Benefits
- Cyanoacrylate adhesive cure accelerator.
- Can be used as pre-activation or post-activation treatment.
- Provides rapid fixture and cure development.
- Very low viscosity for easy application.
- Ideal for automated and production assembly operations.
- Suitable for electronics and component securing applications.
- Compatible with LOCTITE® cyanoacrylate adhesives.
Recommended Applications
- Securing wires and coils to PCBs.
- Tamper-proofing adjustable components.
- Mounting stand-offs and edge guides.
- Board stiffener installation.
- Accelerating fixture speed of cyanoacrylate adhesives.

Technical Specifications
General Properties
Appearance
Transparent liquid
Appearance at room temperature.
Specific Gravity
0.8
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
1 mPa.s
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
