Key Features & Marketing Benefits

PU foaming adhesive is a single-component or two-component foaming adhesive mainly composed of polyurethane. It reacts with moisture in the air to produce expansion and foaming effects, combining bonding and filling functions. Its core characteristics include: forming a flexible or rigid foam structure after foaming, which can tightly fill gaps and holes while generating strong adhesion to various substrates such as metal, concrete, wood, and plastic, achieving multiple functions such as sealing, bonding, insulation, and buffering. It is convenient for construction and can be directly applied by spraying, extrusion, etc. During foaming, it automatically levels and fits the substrate. The cured foam has strong weather resistance, resisting thermal cycling and deformation,suitable for scenarios such as building door and window gap filling, automotive component sealing home appliance insulation layer bonding, and pipeline leakage plugging, providing integrated solutions for working conditions requiring filling, sealing, and structural bonding.
