Cross-linked epoxy-isocyanate blends containing Epidian-6 modified by glycols (in English)

Polimery 2016, No 5, 316


DOI: dx.doi.org/10.14314/polimery.2016.316

Summary
Polymeric films of cross-linked structure may be formed using epoxy-isocyanate blends composed of Epidian-5 epoxy resin, 4,4'-diphenylmethanediisocyanate (MDI), Z-1 polyamine hardener and Epidian-6 epoxy resin modified by glycols. The effect of the component natures and ratio, process temperature and time on the gel-fraction content, as well as film hardness, was examined. The chemistry of the film forming process was determined using infrared-spectroscopy (IR).
Keywords: epoxy-isocyanate blends, polyamine hardener, epoxide, diisocyanate, 1,4-butanediol, cross-linking, gel-fraction, infrared-spectroscopy
