| Résumé : |
Polyurethane coatings have been evolving over the years to meet increasingly more stringent performance requirements. To this end, a number of higher molecular weight polyols as well as isocyanates and isocyanate prepolymers have been developed. Significant levels of organic solvents are required in order to facilitate the application of high perfomance polyurethane coatings prepared from these constituents. With environmental legislation now requiring substantial reduction in coating VOC levels, the polyurethane industry is being forced to either reconsider lower molecular weight components which sacrifice coating performance or to consider new emerging chemistries. Reactive diluents reduce coating viscosity, thereby lowering organic solvent demand, and react into the polyurethane matrix to fill this market need. New research on the concepts, chemistry and performance of reactive diluents for polyurethane coatings is discussed. |
