Anaerobic sealant is a substance that is used in an oxygen-permeable environment, such as metal and plastic pipes, and due to its properties does not change its structure.
In most cases, anaerobic sealant is used in autonomous heating systems as a sealant, which further ensures the smooth operation of the system. Due to its functionality, this substance provides a complete sealing of welds, sealing of threaded joints, sealing threads on pipes and pipe joints, as well as fixing various cylindrical parts from any material.
Anaerobic sealant includes the following substances:
monomers or oligomers from acrylic;
a set of substances that carry out initiating functions;
stabilizers;
various additives such as thickeners, colorants
Substances with such special characteristics first appeared on the market in the 50s in the United States.
In a fairly short timeperiod of time, anaerobic sealant became popular among a wide range of consumers, since no single substance could provide high-quality sealing of narrow gaps. It was added inside the gap, where it interacted with oxygen, resulting in a change in composition, and it turned into a dense substance, thereby protecting the thread from air and other damage.
Exterior sealant must be selected according to where it will be used. In practice, most sealants are used for heating systems as a sealant. In this case, you can purchase an inexpensive substance, since the operating temperature will not exceed 300 and -196 degrees Celsius, because such a temperature regime in the heating system is simply impossible.
The best option in this case would be a sealant, the temperature range of which will be: from - 60 to +150. A rather complex composition of the substance provides protection against acid and alkaline damage that may occur inside the heating system, thanks to this, you can choose any sealant, and you don’t even need to focus on which substance will be used as a coolant.
In the case when an anaerobic sealant is used as a sealant not in the heating system, but for sealing joints after welding, it must be selected taking into account other requirements. First of all, the substance must harden faster after application and more firmly in contact with a certain type ofmetal. In addition, when choosing a sealant, special attention should be paid to the content of coloring pigments in it, this is due to the fact that the color of the material and the color of the sealant should be similar to each other.
Also, do not forget about where the parts sealed or sealed with sealant will be used. With the help of some manipulations with the composition of the substance, it is possible to increase its protection against alkaline and acidic influences. In the event that the parts will be used in a high temperature environment, a sealant with a wider temperature range and operation will already be needed for this.
When choosing a sealant, it is important to consider the environment in which it will be used - for sealing or sealing! First of all, the durability of its functioning and the service life of the parts treated with this substance will depend on this. With a quality anaerobic sealant, you can solve a lot of problems without having to pay a huge amount of money.
