Introduction to PU Sealant
PU sealant, also known as polyurethane sealant, is a versatile and widely used material in various industries. It is formed by the reaction of isocyanates and polyols, resulting in a polymer with excellent sealing properties. PU sealants offer high adhesion to a wide range of substrates, including metals, plastics, glass, and concrete. They have good flexibility, which allows them to accommodate movements and vibrations without losing their sealing integrity. Additionally, PU sealants are resistant to water, weathering, chemicals, and aging, making them suitable for both indoor and outdoor applications. Common uses of PU sealants include construction (such as sealing joints in buildings, windows, and doors), automotive (sealing windshields, body panels), and industrial manufacturing (sealing equipment and machinery).
