The sealant is a kind of solvent-free, single component and curing at room temperature sealant. It shows in paste condition, can squeeze out or daub when operating construction. It will not flow to embed vertical joint and top joint because of the resistance to drop. It presents rubber-like state and is elastic after curing. It can strongly adhere to metal, rubber, wood, cement components, ceramic, glass and so on. Sealing glue is used to fill the void (hole, joint, joint, etc.), have both bonding and sealing functions.
Polyurethane sealant are widely used in civil construction, transportation, etc.
1.In building applications--- fill and seal doors, windows and glass, etc
2. In civil applications--- caulking sealhighway, bridges, runway, etc
3. In automotive applications--- assembly seal the window (mainly windshield glass)
