Summary
Conventional monolithic polyurethanes have good mechanical properties, but they are porous, and posseses poor hydrolytic stability and insufficient permeability. The involvement of toxic components, such as isocyanates, in their production process makes this process extremely toxic and dangerous. Network non-isocyanate polyurethanes (NIPUs) are formed from the reaction between cyclocarbonate oligomers (CCOs) and primary amine oligomers (PAOs). The authors of this paper are studying new types of NIPUs based on acrylic and siloxane CCOs and dendro-polyfunctional siloxane PAOs. These investigations create the possibility to develop high-level UV-stable coatings based on acrylic -dendro-amine systems, which are curable at room temperature, and their most able siloxane-based systems that have good adhesion and mechanical properties. An advanced way of preparing thermo-stable coatings is based on ‘blocked’ non-isocyanate polyurethane.
