For high-quality furniture coatings, solvent borne two-component polyurethane coatings containing are still very much in use today. Along with good workability, they can provide very good chemical and mechanical resistance as well as fast sandability or recoatability with an additional coating layer. For two-component polyurethane coatings, the base paint (containing polyol) is mixed with the hardening component (containing coating isocyanate) before the application. These two components react with one another to form a three-dimensional network. As the reaction progresses, viscosity increases up to the point at which the coating is no longer properly workable. ...
