FILM FORMING URALKYD Russian patent published in 2009 - IPC C09D175/00 C08G63/49 

FIELD: chemistry.

SUBSTANCE: one-pack film forming uralkyd for coating contains an alkyd oligomer with acid number of 15 mg KOH/g, obtained using an azeotropic method based on tall oil fatty acids, pentaerythritol, phthalic anhydride, taken in ratio 72.4:20.1:7.6 wt % respectively, in amount of 41.1 to 43 wt %, Vestanat IPDI isophorone diisocyanate in amount of 9.8 to 10.0 wt %, zinc octoate catalyst in amount of 0.4 to 0.5 wt %, methylethylketoxime in amount of 0.4 wt % and organic solvent - the rest.

EFFECT: cutting on urethane formation reaction time while retaining operational properties, increased stability of composition during storage.
