Sealant is a kind of paste playing a role in waterproofing and sealing of buildings. Sealant becomes rubber elastomer with good recovery after it cures. And it expands after immersed in water to fill the gap, seal and waterproof. It has excellent performance in civil construction as waterproof material. Polyurethane sealant, polysulfide sealant and silicone sealant make up three kinds of advanced sealant in modern society. We manufacture complete sealant related products, such as one-component polyurethane sealant,two-component polyurethane sealant, two-component polysulfide sealant, water-swelling sealant,polyethylene closed-cell foam plate, one-component silicone sealant and two-component silicone sealant. Choosing material reasonably and sealing the buildings correctly are the key process of guaranteeing the construction sealing quality.
Sealants with different kinds have wide application, especially in some large projects. They can be used in various joints, such as expansion joints and deformation joints. They can be used in buildings, tunnel, expressway, airport, railway station, bridge, hydropower project, basement and subway. Besides, they are used in window and door installation, hollow glass adhesion, glass curtain wall and swimming pool. Sealants of different kinds have separate application area. You can choose sealants correctly based on your demand.
Some matters need to note:
Take protective measures during using sealant to avoid injury.
Clean the surface of joints first to make the bonding effect better.
Choose right sealant based on the properties and application areas.
Confirm if it is necessary to do base coating.
If you use the two-component sealant, use it up within 2 hours. Because it cures with time going by, making the construction hard and resulting in waste.
