Polyurethane technologies have demonstrated their applications in a variety of seamless polymer flooring systems. Aliphatic polyurethanes are widely used as topcoats since they provide combinations of good color stability, gloss retention, abrasion resistance, chemical resistance, and weathering resistance. Recent development in polyaspartic chemistry offers more options in coating thickness, curing temperatures, and solids content. Aromatic polyurethanes are used in resilient coatings and modified concretes due to their flexibility, toughness, and thermal shock resistance. This article will discuss important aspects of these technologies with particular focus on characteristics related to seamless flooring.
