Kamatani, Yoshio published the artcileReaction of an oxadiazinetrione derivative and its application to polyurethane coatings, SDS of cas: 2212-32-0, the main research area is isocyanate oxadiazinetrione derivative crosslinker; amine catalyst urethane formation; phosphine catalyst urethane formation; lead octanoate catalyst; polyurethane coating crosslinking agent.
In the reaction of 3,5-bis(6-isocyanatohexyl)-2H-1,3,5-oxadiazine-2,4,6(3H,5H)-trione (I) [50639-37-7] with H(OCH2CH2)2OMe [111-77-3] in solution at 70°, tertiary amines, Bu3P, and Pb octanate were good catalysts, giving conversions of 87-100%. In the reaction of I with Bu methacrylate-hydroxyethyl methacrylate-iso-Bu methacrylate-styrene copolymer [77402-19-8] to give a coating, tertiary amines were suitable catalysts. In curing polyurethane coatings at relative humidity (RH) 0% and 50%, I is a little more reactive than tris(6-isocyanatohexyl)biuret (II), and the dependence of I reactivity on RH is smaller than that of II. Coatings from I-based polyurethanes had good curability in early stages, while those from II- and tris(6-isocyanatohexyl)isocyanurate-based polyurethanes required 2-3 times longer to attain the same hardness.
