Investigation of the composition of hybrid polyurethane-polyurea coatings modified with nanoscale carbon fillers

The industrial polyurethane/polyurea coatings recommended as anticorrosive materials for application in Gazprom were modified with carbon nanofillers, including fullerene C60, fullerene soot, and a batch of detonation nanodiamond. The kinetics of curing of the modified coatings, their mechanical and anticorrosive characteristics, as well as water absorption, were studied. It was shown that the incorporation of carbon nanosized fillers significantly improves the performance characteristics of polyurethane/ polyuria anticorrosive coatings.
