Лако-красочные материалы — производство

Unlike most other resin systems, polyurethane resins, in most cases, are not supplied to coating formulators, but rather their com­ponents — polyols and isocyanates — are supplied. Coating formulati­ons are made using these components, and in most cases, urethane linkages (polyurethane resins) are produced during the curing process. This offers a great deal of freedom to formulators to offer products with different compositions and curing chemistry.
