Loctite anaerobic threadlockers prevent threads from loosening and loosening due to vibration. Traditional mechanical methods of securing threads (spring washers, nuts with nylon inserts, etc.) loosen over time because they do not fill the voids in the threads. Anaerobic products stick together and fill all empty areas in the thread, which eliminates mutual movements and vibrations of threads, and significantly increases reliability and reduces the risk of loosening of elements (one of the main causes of serious failures of machines and devices).

How to use threadlocker?

Threadlocker adhesives cure in anaerobic conditions. This process occurs when the adhesive is cut off from contact with air (oxygen) and at the same time is in contact with metal. The adhesive does not harden before the connection is made - this unique property allows for precise filling of micro-spaces with a homogeneous mass and facilitates its application.
In the case of many machines, threadlocker is needed to ensure the durability of the connections of elements. How to use this type of product? Application is simple thanks to the appropriate consistency and packaging with a narrow applicator. Before applying the adhesive, check the recommendations in the manufacturer's instructions.

How long does it take for threadlocker adhesive to dry? The drying time depends on many factors, including the type of preparation, environmental conditions and layer thickness. Full hardening usually takes from 24 to 72 hours. Until then, the connections should not be subjected to full mechanical loads.

Hydraulic thread adhesive – what makes it stand out?

Hydraulic thread adhesive is a specialist product designed to seal and secure threaded connections in hydraulic systems. Its properties include:

• resistance to high pressure - allows to maintain tightness of connections and prevent leaks,
• chemical resistance - does not react with substances present in hydraulic systems,
• resistance to high temperatures - allows to maintain the properties of the glue even in extreme conditions,
• thread locking effect - prevents them from loosening under the influence of vibrations and mechanical loads.

Thanks to its features, the hydraulic thread glue, which you can buy in the Melkib store, will ensure the reliability and durability of hydraulic systems.

Green thread glue and red thread glue - what are the differences?

You have certainly noticed that the products have different colors. Thread glue is usually characterized by an intense shade, which not only makes the preparation visible, but also allows to verify where it was applied. Manufacturers also use colors to mark products with different properties. An example is Loctite threadlocker. Types of adhesives have the addition of specific dyes, for example:

• blue threadlocker is moderately dismantled,
• green is difficult to dismantle, the strongest threadlocker.

Advantages of Loctite thread sealing products

• high effectiveness despite vibrations of elements and high temperatures
• prevent loss of tension due to loosening of connecting screws
• additionally seal the thread, prevent leaks and corrosion
• prevent seizing and seizing of the connection, making dismantling easier
• reduce product storage costs - one adhesive secures many sizes and types of threads as opposed to traditional mechanical methods

What adhesive to secure threads choose?

When choosing a product, you should pay attention to the following factors:

• what is the size of the thread being secured?
• will the screw be dismantled? How often?
• what temperatures will affect the thread?
• what material is the thread made of?

Based on this data, you can select the optimal product. From experience, we know that most applications can be performed with Loctite 243, 270 and 222.

How to use threadlocker correctly?

It is best to clean and degrease the thread before applying an anaerobic threadlocker, while some adhesives, such as Loctite 243, tolerate slight surface oiling. Loctite 7063 or Loctite 7061 are perfect for degreasing. Then apply a drop of anaerobic glue to the male thread - screw and screw in. When screwing in the screw, the glue will be spread over the surface of the thread. After screwing in the screw, you have a few to a dozen minutes to adjust the connection depending on the selected glue and type of material. After that, do not touch the thread anymore. This can break the bonds formed during the curing of the anaerobic glue, which will result in improper securing of the screw.

Red, green or blue thread glue?

The colors initially indicate the type of glue, but they should not be strictly followed. Blue glue Loctite 243 is a product of medium strength, i.e. medium disassembly. It should be used for threads that may require disassembly using hand tools.Loctite 222 in purple is an easy-to-disassemble, low-strength anaerobic adhesive, recommended for applications where easy screw disassembly is required and for small threads, e.g. in electronics. An anaerobic adhesive that is difficult to dismantle is Loctite 270 - green. It should be chosen when we want very strong protection, in its case dismantling is only possible after heating the thread to a minimum of 200-250 degrees Celsius. Such a high temperature causes the adhesive to lose its strength and allows the thread to unscrew.

How to secure a screw that has already been screwed in without unscrewing it?

If you want to secure a screwed in thread against loosening, use Loctite 290 capillary adhesive. Thanks to its very low viscosity, the adhesive will penetrate deep into the thread coils, which will secure the thread and additionally seal the connection.

How long does it take for the thread adhesive to dry?

The speed of the adhesive curing depends on the choice of adhesive and the type of surface on which it is used. Passive surfaces such as aluminum, stainless or galvanized steel prolong the curing of the adhesive, while active surfaces such as brass and copper significantly accelerate the drying of the anaerobic adhesive. Usually, the initial curing time is in the range of several to several dozen minutes.

Anaerobic threadlocker won't cure, what could be the reason?

Anaerobic adhesives cure between two metal surfaces and after cutting off the access of air. If the surfaces are not metal or the gap is too large and air has access, the adhesive will not cure.

How to speed up the curing of screw adhesive? How to cure the adhesive flow?

If it is necessary to speed up the drying of the adhesive, Loctite 7649 activator should be used. It can also be used to cure excess anaerobic adhesive that has flowed out of the thread. It should be noted that the use of an activator weakens the strength of the adhesive.

How to unscrew - dismantle a glued thread?

In the case of adhesives that are easy to dismantle and are moderately easy to remove, it is usually enough to use hand tools and simply unscrew using greater force. If the thread was secured with a high-strength adhesive, it will be easiest to heat the connection to a minimum of 200-250 degrees. Then the adhesive will lose its strength and it will be possible to unscrew the screw without any problems. In the case of strong adhesives, do not use impact wrenches or try to unscrew the thread using great force. This can damage the screw thread or even break the screw itself. In the case of very large threads, even weaker adhesives will require a very large force to unscrew due to the large surface area. Then it will also be safer to raise the temperature.
