Polyurethane

Polyurethane (PU) adhesive is a high-performance bonding solution known for its exceptional flexibility, strength, and durability. It can be formulated as one- or two-component systems and offers excellent adhesion to various substrates such as wood, metal, and composites. PU adhesives are ideal for demanding woodworking and construction applications that require strong structural bonds and superior weather resistance.

IWG’s polyurethane (PU) adhesives are two-component, reactive, high-solid-content bonding solutions designed for industrial and woodworking applications. Featuring slight foaming and the ability to cure at room temperature or under heat, these adhesives deliver exceptional bonding strength, durability, and weather resistance.
