Preparation of Solvent-Free Moisture Curable Heavy Anti Corrosion PU Coating

Article Preview

Abstract:

Isocyanate-terminated prepolymer was synthesized by reaction of polyether polyols with toluene diisocynate and was modified by CaO and hydroxyl silicone oil, then solvent-free moisture curable heavy anti corrosion PU coating was prepared. The structure of cured coating was characterized by FTIR spectra and SEM. The mechanical properties, water tolerance, water contact angle of cured coating were analysed. The results showed that the solvent-free moisture curable heavy anti corrosion PU coating had the best combination property with 5% polyether polyols N210, 4% CaO and 4% hydroxyl silicone oil.
