Session 6: Polyurethanes I
Polyurethane coatings have emerged as undisputed systems of choice for myriads of end-use environments due to their broad range of thermo-mechanical properties combined with versatility of applications on a variety of substrates. However, the use of isocyanates in their production has raised concerns. Addressing this need, a number of novel approaches and some commercial products have started making debut in the commercial market space. Building onto the cyclic carbonate / Amine chemistry, we have successfully developed a Non-Isocyanate Polyurethane (NIPU) platform with a library of functional building blocks derived from a range of polycyclic carbonates and polyamines. These tunable NIPU building blocks can be customized for water-based, high-solid and UV-curable coatings. This presentation will focus on design and synthesis of NIPU systems for two-component low-VOC high-solid (2K-HS-NIPU) as well as UV-curable (UV-NIPU) coatings. Both 2K-HS NIPU and UV-NIPU coatings have been evaluated for advanced military coating applications. The results suggest that these coatings meet or exceed environmental as well as performance requirements for military coatings. This NIPU platform can be successfully leveraged for formulating a broad range of advanced coatings in the high performance protective and industrial coating space.
