Water-based polyurethane adhesive joint concrete water-swelling sealant polyurethane construction joint sealant
Brief introduction:
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.
Features:
Strong adaptability
Good wear-resisting performance
High mechanical strength
Good Bonding performance
Good elasticity, has excellent resilience, and can be used for dynamic joint
Good flexibility in low temperature
Good weathering resistance, service life can reach as long as 15 ~ 20 years
Good oil resistance
Resistance to biological aging
Reasonable prices
