Anaerobic sealant is a substance that is used in an oxygen-permeable medium, for example, in metal and plastic tubes, 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 ensures further uninterrupted operation of the system. Due to its functionality, this substance provides 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 perform initiating functions;
- various additives such as thickeners, colorants.
Substances with such special characteristics, first appeared on sale in the USA in the 1950s.
For a fairly short period of time, anaerobic sealant has become popular among a wide range of consumers, since not a single substance could provide high-quality sealing of narrow cracks. It was added inside the gap, where there was an interaction with oxygen, as a result of which a change in composition occurred, and it turned into a dense substance, thereby protecting the thread from air and other damage.
The sealant for outdoor use 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 is a sealant, the temperature range of which will be: from - 60 to +150. The rather complex composition of the substance provides protection against acid and alkaline damage that can 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 the anaerobic sealant is used as a sealant not in the heating system, but for sealing the joints after welding, it must be selected taking into account other requirements. First of all, the substance should harden faster after application and be more firmly in contact with a certain type of metal. 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 a 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 acid effects. In the event that the parts will be used in an environment with high temperatures, a sealant with a wider range of temperature conditions and functioning will already be needed for this.
When choosing a sealant, it is important to consider in which environment 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. Thanks to high-quality anaerobic sealant, you can solve many problems, without the need to pay huge amounts of money.
