Abstract
The coating described herein attempts to provide this solution by synthesizing alkoxysilane-terminated N-substituted urea resins, then formulating them into moisture-curable single-component (1K) topside coatings. These coatings will provide greater external stability (to UV and visible radiation), cleanability, flexibility, cure times and lower VOC content than the currently qualified silicone alkyd topside coatings that are found on Navy ships. The single-component coating can include at least an alkoxysilane-terminated N-substituted urea resin, a reactive diluent, a pigment, a filler, and a catalyst. The resin can include an amino-functional silane substituted at the N-position and a non-aromatic isocyanate.
