Polyurethanes for Coating, Adhesives, and Other Applications

An interesting group of polyurethane (PU) materials are coatings, adhesives, sealants, and thickeners. A wide base of raw materials and various methods of PU synthesis allows production of materials with a wide range of properties that can be commonly used in many industries. This chapter describes the main types of PU coatings and adhesives and special application PUs and the methods of their production. The materials described in this chapter can be obtained from one-component and two-component systems using organic solvents, aqueous dispersions, powders, or solvent-free systems. There has been a growing interest in ecological solutions aimed at the elimination of organic solvents. For this reason, the interest in obtaining PUs from aqueous dispersions and other proecological solutions is still growing.
