| Résumé : |
Industry has been moving away from traditional solvent-borne coatings often to water-based systems. Manufacturers also try to provide formulators with cross-linkers and adhesion pro-moters that meet changing and challenging market needs. Isocyanate chemistry is a very useful tool for achieving this goal. The focus is on further reducing or eliminating VOCs, providing flexibility over a full pH range and wherever possible delivering solutions that have minimal impact on health, safety and the environment. |
