Abstract
Polyester-urethane polymers, prepared from the reaction of specific molar ratios of diisocyanates with specific mixtures of polyesterdiols, glycols, triols and tetraols, and having 4-10 reactive isocyanate groups are further reacted with hydroxyalkyl acrylates through the free isocyanate functionality to provide oligomers having from about 4-10 acrylates units per each mole unit of polyurethane chain. Such polymers when crosslinked under ultraviolet radiation in the presence of photosensitizers, specific reactive monofunctional acrylate solvents and multifunctional acrylate cross-linking agents cure without air inhibition to yield superior 'wet look' finishes especially useful for coating metal, wood and floor tile.
