Description:
BILIN A2 Polyurethane Foam is a high-performance one-component adhesive foam that cures rapidly when exposed to air. It forms a strong bond with metal, wood, concrete, and masonry, offering excellent temperature stability (adapting to -30°C to 90°C), minimal shrinkage, and outstanding expansion performance—ideal for quick gap-filling applications in construction.
