Polyethers for Polyurethane Adhesives:Interfacial chemical bonding, wide application range of substrates The prepolymer of terminal NCO group formed by polyether and isocyanate can react with various functional groups containing active hydrogen to form interfacial chemical bonds, and has strong adhesion to various materials. Therefore, it can not only bond porous materials such as foamed plastics, ceramics, wood and fabrics, etc., but also bond a variety of metals, inorganic materials, plastics,...
