Introduction of pu sealant

A sealant is a form of material, which is used to seal gaps and holes to make something airtight or watertight.When you use sealant, you effectively form a seal, which prevents the movement of fluids and liquids.
Sealant is sometimes compared to caulking.
The main difference between building caulking and sealing is the flexibility of the seal. If you include mastic sealing in this equation sealants can not only seal but can also be used as an effective adhesive.Sealants tend to be made from much more flexible materials.
