Polyurethane sealants are high-performance joint and waterproofing materials known for their excellent elasticity, strong adhesion, and long-term durability. They bond securely to concrete, stone, metal, glass, and wood, making them ideal for construction joints, façades, flooring, and infrastructure projects. With superior resistance to weathering, chemicals, and movement, polyurethane sealants provide a reliable solution for both indoor and outdoor applications.
