"This dissertation focuses on the development of environmentally benign coatings involving the application of the Michael addition reaction and its adducts in the composition of polymeric resin binders. The Michael addition of primary amines to α,ß-unsaturated esters was briefly investigated to synthesize amine Michael adducts which contain active secondary amine hydrogens to be used as hardeners for epoxy resins and reactive diluents for polyols to react with polyisocyanates. Both acrylates and methacrylates were used as the Michael acceptor, while ammonia, methylamine, npropylamine, and n-butylamine were utilized as the nucleophile. The Michael adducts, as well as mixtures with commercial hardeners were evaluated as epoxy hardeners.

The thermal stability of cured epoxy with TTP A, trimethylpropane tri(α-methyl-ß-(N-(n--propyl)-amino ))-propionate as well as with co-hardener were investigated using Thermal Gravimetric Analysis (TGA). High solids epoxy primers were formulated with TTP A and commercial hardeners that meet military specifications. The amine Michael adduct, TTPA was successfully utilized to increase the xenon flashlamp removal of epoxy primers by utilizing the thermal reversible property of amine Michael adduct. In addition, carbon black as an energy absorber also enhanced the epoxy primer removal by a xenon flashlamp. The adduct of the Michael addition, TTPA was used as a reactive diluent in the polyol resin to formulate high solids polyurethane coatings. The properties and performance of the polyurethane coatings were determined following ASTM standards"--Abstract, page iv.
