Loctite 245/50ml – Medium Strength Threadlock

LOCTITE 245 Medium strength, medium viscosity, large threads threadlocker, Breakaway torque 13Nm.

Loctite 245 is designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration.

Product Description

Chemical Type: Dimethacrylate ester
Appearance (uncured): Blue liquid
Fluorescence: Positive under UV light
Components: One component: Requires no mixing
Viscosity: Medium
Cure: Anaerobic
Secondary Cure: Activator
Application: Threadlocking
Strength: Medium

Typical Curing Performance

Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph shown in the data sheet shows the breakaway strength developed with time on M10 black oxide bolts and steel nuts compared to different materials and tested according to ISO 10964.

Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. Gaps in threaded fasteners depends on thread type, quality and size. The graph shown in the data sheet shows shear strength developed with time on steel pins and collars at different controlled gaps and tested according to ISO 10123.

Cure Speed vs. Temperature
The rate of cure will depend on the temperature. The graph shown in the data sheet shows the breakaway strength developed with time at different temperatures on M10 black oxide bolts and steel nuts and tested according to ISO 10964.

Cure Speed vs. Activator
Where cure speed is unacceptably long, or large gaps are present, applying activator to the surface will improve cure speed. The graph shown in the data sheet shows the breakaway strength developed with time on M10 zinc dichromate steel M10 nuts and bolts using Activator 7471 and 7649 and tested according to ISO 10964.
