The basic properties of sealant
To ensure its performance and shape of a complete recovery;
Can resist the telescopic movement, displacement and deformation of the joints; in the deformation by the joints,
And other media low penetration;
Good embedded, crowded construction, storage stability, non-toxic or low toxicity; liquid, gas
The sealant is a fluid or extruded material that is filled with a closed joint that can rely on embedded drying, temperature changes, solvent volatilization, chemical crosslinking material stability and bonds, and progressively solid glue, viscoelastic behavior Or elastomeric sealing material.
