2760 High-Strength Loctite Threadlocker for Heavy-Duty Bolts

Product Overview

LOCTITE 2760 is a high-performance thixotropic threadlocker designed to meet the demands of heavy-duty industrial applications. As a premium anaerobic adhesive, it combines exceptional strength with a remarkably fast curing process, eliminating the need for additional activators in most scenarios. With the model number 2760 and product code 3506990000, this one-part liquid solution adheres to strict quality standards, making it a trusted choice for professionals across various sectors.

Its unique formulation ensures reliable performance in critical environments, where bolted joints are subjected to extreme stress, vibration, and temperature fluctuations. Whether used in manufacturing, construction, or transportation, LOCTITE 2760 provides long-lasting security for threaded assemblies, reducing the risk of loosening and ensuring operational safety.

Features

Rapid Curing Mechanism

One of the standout features of LOCTITE 2760 is its fast curing capability. Depending on the substrate, it can achieve full cure in as little as 1 hour, significantly reducing assembly time compared to traditional threadlockers. This rapid curing process enhances productivity, allowing for quicker turnaround in high-volume production lines or time-sensitive projects.

High-Strength Bonding

Formulated for heavy-duty use, this threadlocker delivers high-strength bonding that withstands intense mechanical stress. It effectively locks threaded fasteners, preventing loosening caused by vibration, shock, or thermal expansion. This strength makes it ideal for applications where joint integrity is paramount, such as in heavy machinery and industrial equipment.

Thixotropic Property

The thixotropic nature of LOCTITE 2760 ensures easy application and minimal mess. It remains in place after application, reducing the risk of drips or runs on vertical or overhead surfaces. This property also helps in controlling the amount of adhesive used, minimizing waste and ensuring precise coverage on threaded areas.

UV Fluorescence for Quality Control

A unique advantage of LOCTITE 2760 is its ability to fluoresce under UV light. This feature simplifies quality control inspections, allowing operators to quickly verify proper application and coverage of the threadlocker. It ensures that every fastener is adequately treated, reducing the chances of oversight and improving overall assembly reliability.

Anaerobic Cure Type

Operating on an anaerobic cure mechanism, LOCTITE 2760 cures in the absence of air, when in contact with metal substrates. This ensures that the adhesive hardens only in the threaded interface, avoiding unnecessary curing on external surfaces and ensuring a strong, focused bond.

It provides a reliable bond that resists the vibrations and temperature changes experienced during vehicle operation, contributing to the overall safety and performance of automobiles, trucks, and other vehicles.

FAQ

How long does LOCTITE 2760 take to fully cure?

The curing time of LOCTITE 2760 depends on the substrate, but it can reach full cure in as little as 1 hour under optimal conditions. Factors such as temperature, humidity, and the type of metal can affect the curing process, but in most industrial settings, it cures quickly enough to meet tight production schedules.

Can LOCTITE 2760 be used on all types of metals?

LOCTITE 2760 is designed to work with most common metals, including steel, iron, and brass. However, it may not be suitable for non-ferrous metals such as aluminum in certain cases. It is recommended to test the product on the specific metal substrate before full-scale application to ensure compatibility.

Is LOCTITE 2760 resistant to chemicals and solvents?

Yes, once fully cured, LOCTITE 2760 exhibits good resistance to a wide range of chemicals, oils, and solvents commonly encountered in industrial environments. This resistance helps maintain the integrity of the bond even in harsh conditions, ensuring long-term performance.

How can LOCTITE 2760 be removed if needed?

To remove LOCTITE 2760 after curing, heat the bonded assembly to a temperature of around 250-300°C (482-572°F). This softens the adhesive, allowing the fasteners to be loosened. For smaller or more delicate components, mechanical methods such as using a wrench or pliers may be sufficient, especially if the bond is not subjected to extreme stress.

What packaging options are available for LOCTITE 2760?

LOCTITE 2760 is available in various packaging options, including barreled, bagged, boxed, and palletized forms. Custom packaging solutions can also be provided to meet specific customer requirements, ensuring convenient storage and handling in different industrial settings.
