Liquid sealant effect it has five broad areas of application

Sealant is a primer with the shape of the sealing surface deformation, not flowing, there is a certain adhesion of the sealing material. Configuration is used to fill the gap , in order to play the role of the adhesive seal . Typically bituminous , natural resins or synthetic resins such as natural rubber or synthetic rubber or dry dry viscous material as the base material , with talc , clay , carbon black, titanium dioxide and inert fillers such as asbestos , then add plasticizers, solvents , curing agent and catalyst is made. Sealant has good sealing performance , and good heat resistance, pressure resistance, dense medium characteristics, use of simple , commonly used in mechanical and electrical products still seal between joints , as well as more complex threaded joints sealing , etc. , sealants, liquid sealant is generally divided into two categories with anaerobic ,security seals  and more commonly used liquid sealant role has the following five effects:
1 , the surface effect
No matter how solid gasket compression , it will not completely fill the joints on uneven, there will always be a gap at the interface , and the liquid sealant was able to fill all depressions , showing a good sealing effect.
2 , adhesion results
Liquid sealant in liquid form , has a certain viscosity , having a joining surface of the metal adhesion , sealing beneficial .
3 , the thin film effect
In the joints between the liquid sealant is screw fastening , the formation of a film with the same space at the same time is very consistent with the surface . Meanwhile , the thinner the film , the greater resilience , the better seal.
4 , flow and pressure resistance
Using liquid metal sealant joints , gaps are generally less than 0.1mm , and the liquid sealant is a liquid of high viscosity , it is difficult to flow , thereby maintaining its good sealing .
5, the volume change and mobility
Solid gasket leak-proof effect is the compression of the cushion sheet elastic deformation . The liquid sealant is leakproof volume in the compression and stretching deformation , it does not exist solid gasket compression deformation, so there is no compression fatigue , pull tight seals elastic failure , stress relaxation and other phenomena , and it is always connected adhesion of the interface , the interface can be prevented leakage .
