Sealant is a substance used to prevent fluids from passing through the surface or joints or
openings in materials. Injectable Sealant is used
in All kinds of mechanical static joints to
prevent intrusions of external impurities and internal material leakage. In
construction, the sealant is also used as filler thing that can block the
transmission of dust, sound and heat.
Sealants show many properties. Such as anti-leakage, waterproof, anti-vibration, sound insulation, heat insulation and other functions. They seal the top structure to the substrate and are particularly effective in water repellent treatment by retaining moisture in/out the components in which they are used. They can provide thermal and acoustic insulation and can act as a fire barrier. Sealants can also be used for simple smoothing or filling. They are often required to perform several of these functions at once.
The caulk sealant has three basic functions: filling a gap between two or more substrates; it forms a barrier through the physical properties of the encapsulant itself and adheres to the substrate; and at the intended service life, conditions of use and Keep the sealing performance in the environment. Compared to welding, sealants are simpler and more reliable
