STRALNINGSHERDBAR AKRYLERAD ELLER METAKRYLERAD POLYURETAN |
摘要 |
Radiation curable acrylated polyurethane is porduced by (a) producing an isocyanate-terminated intermediate by coreacting an organic diisocyanate with a combination of organic tri/tetraol and organic diol, said combination being chosen from polyester tri/tetraol-polyether diol and polyether tri/tetraol-polyester diol combinations; (b) reacting the isocyanate-terminated intermediate with an hydroxyacrylate such as 2-hydroxyethyl acrylate. Unexpectedly, the oligomer has desirably low viscosity, yet cures upon exposure to radiation to a coating having good physical properties. |
