Abstract
Waterborne, very low volatile organic compound (VOC) content Navy haze gray (NHG) coatings were developed using vegetable oil macromonomer (VOMM)-based latexes. The coatings successfully met the requirements of specifications MIL-PRF-24635C and MIL-PRF-24569A. The monomer and latex syntheses were scaled up to prepare 20 gallons of the NHG coating, which was shipped to two Florida locations, Pentech and NRL, for evaluation on December 2, 2008. AFM characterization techniques developed to track film coalescence as a function of drying time indicated that the coalescence rate increased with increasing VOMM content. (2) BoltornTM dendritic hydroxylated esters were evaluated as high oxygen barrier biodegradable films and coatings. Improved mechanical performance was achieved via covalent linking of dendritic molecules with 1,6-hexamethylene diisocyanate.
