Threadlocker

Thread Locking Fluid or threadlocker is a thin, single-component adhesive that is applied to the threads of fasteners, such as screws and bolts, to prevent loosening, leakage, and abrasion.

Thread lock fluids are generally methacrylate-based and treated anaerobically. Thread lock fluid is a thixotropic fluid: under shear stress, it exhibits a time-dependent decrease in viscosity. This allows it to flow well over time, but still withstand short-term shear, such as in vibrations or shocks.

Thread-lock fluid is typically sold in small containers in quantities from 5 milliliters (about 1 teaspoon) to 250 milliliters (8.5 US fluid ounces). Threadlocker is also sold in stick form and in tape form, similar to Teflon tape.

Thread locking fluid can be applied before or after installation, depending on the type. Threadlockers are available in 'permanent', 'removable' and 'low-strength fitting varieties. Many brands color the container and the liquid itself to indicate the degree of stability. Low-strength types prevent loosening with vibration, but still easy to disassemble. Removable types resist greater amounts of vibration, but they can still be removed with hand or power tools. The most powerful permanent screw fasteners have a shear strength of 3000 psi (21 MPa). The applied torque required to permanently loosen a bolted fastener may exceed the elastic limit of the locking itself, so attempting to remove it by force could distort the locking shaft. However, permanent, high-strength screw fasteners will likely become removable when the assembly is heated, typically to 230°C (450°F).

Working temperatures of threaded fasteners are usually limited to 150°C (300°F), which is below the softening point of a methacrylate polymer. Above this temperature, the material softens and resistance decreases.

Thread Sealants

A thread sealant is essentially an anaerobic adhesive that, when applied between two parts or threaded metal surfaces, fills in the gaps and cures in the absence of air to form a durable thermoset plastic layer around the sealant.

As a result, you receive a high-pressure seal almost immediately, which is generally set to equal the burst pressure of the plumbing system. In this way, thread sealants effectively prevent leakage with an airtight seal, even under extreme temperature fluctuations or vibrations. Not surprisingly, Thread sealants have become a formidable solution for various industrial applications.

How do you choose a Thread sealant to suit your project requirements?

If you want to choose the perfect product for your sealing needs, start with the questions listed below:

• What type of substrate do you need to seal?

• What is the maximum pipe thread size?

• What is the temperature resistance required for installation?

As you answer each of the above questions, you can estimate the technical specifications of your solution and choose the ideal type of thread sealant for your repair job. However, you should always rely on a trusted brand like LOCTITE to ensure high-quality repair solutions for your pipeline leaks.

Gasketing Compounds

A gasket compound is a mechanical seal that fills the space between two or more mating surfaces, generally to prevent leakage from or to associated objects while under pressure. Due to the potential cost and safety implications of defective or leaking gaskets, it is critical that the correct gasket material is selected for the needs of the application.

The gaskets allow for "less than perfect" mating surfaces on machine parts where unevenness can be filled. Joints are usually produced by cutting sheet materials.

Gaskets for specific applications, such as high-pressure steam systems, may contain asbestos. However, due to the health risks associated with exposure to asbestos, non-asbestos gaskets are used when practical.

In general, it is desirable that the gasket be made of a material produced, to some extent, in such a way that it can deform and tightly fill the space for which it is designed, including small irregularities. Some types of joints require a sealant to be applied directly to the joint surface in order for them to function properly.

Some piping gaskets are made entirely of metal and rely on a seating surface to close them; The spring properties of the metal are used (up to the elastic limit of the material, but not exceeding it). This is the case for some "ring joints" (RTJ) or some other metal gasket systems. These gaskets are known as R-con and E-con pressure type gaskets.

Retaining Compounds

Retaining compounds are a type of adhesive first invented in the 1960s that are used to fill the gap between mechanical components, as well as to fit bearings inside retainer cylinders, shafts, and bushings.

Although retention compounds are commonly used in bearings in housings or in shafts, they have a wide range of other applications and benefits. These applications include mounting gears and pulleys on shafts, retaining cylinder liners, securing oil fill tubes in castings, and restoring precision to worn-out machine tools.

Retaining compounds help prevent the deformation of metal components when used to secure bearings. Simply apply the retaining compound to the outside of the bearing before inserting it into the housing, so that any gaps between the bearing and housing are closed.

Retaining compounds that are used to fill the gaps between different mechanical parts are designed to have different viscosities. For example, low viscosity retention compounds have a viscosity around the 1000 mPa * s range and can be used for gaps up to 0.15 mm. To bridge gaps larger than this, retention compounds with higher viscosity, generally greater than 2000 mPa*sec, should be used instead.

Cleaners and Primers

The cleaner and primer dosing cabinet is mainly composed of a material (cleaner/primer), a recirculation pump (primer only), a cleaning fluid tank (usually water or solvent), a dosing unit, and material control valves.

Depending on product characteristics and specific application parameters, the dosing systems used can range from nitrogen systems, diaphragm pumps, and peristaltic pumps to screw dosing units.

The recirculation system and/or mixing system are key to the correct operation of the Primer application equipment. By continuous product recycling, air entry into the circuit is prevented and primer crystallization is avoided so that no obstructions are created in the system. In the case of water-based primers, this guarantee is best achieved by a low-speed mixing system within the primer tank itself.

Both material recycling and the cleaning stipulated in the Maintenance Manual are essential to keeping your Primer application equipment in perfect condition.

The different techniques currently available for applying Cleaner and Primer are based on spraying (little used for environmental reasons), felt, foam, and applicator (either with a brush or with a synthetic compound). Depending on the characteristics of the product to be applied, its application parameters, and the different needs of the customer, one or another application technology will be used.

Depending on the configuration chosen, there are different automatic rod feeding systems that differ according to the degree of autonomy required.
