3M 7100039236 Threadlocker TL90 Purple 50 Ml

Product Description

The 3M 7100039236 is a purple, very low viscosity wicking grade threadlocker designed for medium torque removal applications. Sold as Scotch-Weld Threadlocker TL90, this 50 mL anaerobic adhesive is formulated to penetrate pre-assembled fastener assemblies by capillary action, locking threads without requiring disassembly before application. It resists vibration and shock loading while also providing corrosion protection at the thread interface. Licensed tradespeople and maintenance technicians working on mechanical assemblies, pumps, motors, and threaded fastener systems use this product where post-assembly thread locking is required.

Threadlocker TL90 is suited for residential and light commercial maintenance work as well as industrial applications where pre-assembled parts cannot be conveniently taken apart before securing. Its wicking grade formulation allows the liquid to flow into the thread engagement zone after the fastener is already in place, making it a practical choice for service and repair scenarios across HVAC, plumbing, electrical equipment, and general mechanical systems. Removal is performed with standard hand tools after the cured adhesive is broken free.

Key Features

• Very low viscosity wicking grade formula penetrates pre-assembled fastener threads without disassembly
• Medium torque removal strength allows hand tool breakaway after cure
• Protects threads against corrosion at the fastener interface
• Resists vibration and shock, preventing loosening under dynamic loads
• Purple color provides visual confirmation of application
• 50 mL bottle size suited for service and repair use

Compatibility

Designed as an OEM-style threadlocker for use on standard threaded metal fasteners in pre-assembled mechanical assemblies where wicking grade penetration is required.

Installation Notes

Application is typically performed by maintenance technicians and mechanical service professionals. Clean fastener surfaces of oil, grease, and debris before applying to promote proper cure. Apply sparingly to the thread engagement area and allow full cure time before returning the assembly to service. Follow the manufacturer application guide and applicable workplace safety guidelines when handling anaerobic adhesives.
