Main features

  • Medium-Strength Hand-Tool Removal
  • 8 N m Breakaway Torque
  • Controlled One-Part Application

Product Description

LOCTITE GRD CV Medium-Strength Threadlocker is a one-part blue anaerobic liquid for locking and sealing fine-threaded nuts, bolts, and studs. Its 100 to 250 mPa s viscosity supports controlled placement on threaded metal assemblies, while the medium-strength cured bond allows removal with standard hand tools. The material requires no mixing and cures after assembly when confined between close-fitting metal surfaces. After 24 hours at 22 deg C, it develops 8 N m breakaway torque on 3/8 x 24 grade 2 steel fasteners under ISO 10964 testing. Applications include fine-thread fasteners that need secure retention with planned service access.

Key features

  • 8 N m Breakaway Torque: Typical breakaway torque is measured after 24 hours at 22 deg C on grade 2 steel fasteners.
  • Medium-Strength Serviceability: The cured assembly can be removed with standard hand tools.
  • Controlled One-Part Viscosity: The 100 to 250 mPa s liquid requires no mixing before application.

Applications / Suitable for

  • Fine-threaded nuts, bolts, and studs
  • Threaded assemblies requiring hand-tool removal
  • Metal fastener locking and sealing

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
100 to 250 mPa.s
Thermal Properties
Specific Heat Capacity
Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. The specific heat capacity of a material is a physical property. It is also an example of an extensive property since its value is proportional to the size of the system being examined.
300 J/(g⋅°C)
Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance. Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
0.1 W/m.K
Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
