| Résumé : |
Polyurethane coatings are formed from a chemical reaction between a poyol and a polyisocyanate hardener. Epoxy polyol resin was synthesized by reacting epoxy resin (diglycidyl ether of bisphenol A type), diethanolamine, cellosolve acetate and xylene at refluw temperature 60°C to 70°C for 6 Hrs. Two component polyurethane coatings were prepared by blending of epoxy polyol and hexamethylene diisocyanate (HDI) hardener. After the film coated with the prepared polyurethane coating, the various physical properties and mechanical properties were measured and compared. The formation of the polyol and polyurethane was supported by FTIR spectral data. |
