Résumé : |
Uralkyds, the simplest type of urethanes in which curing occurs by oxidation of the double bonds in its fatty acid portion have been prepared and the properties of their paint formulations are determined and compared with those of alkyd and two pack polyurethane. The practical test data of physico-chemical, mechanical and corrosion resistant properties indicate the superiority of uralkyds over alkyds and their proximity to two pack polyurethane coatings. Based on the findings uralkyds could be recommended for protective coating systems where quick air drying, ease of application, better protective properties and low cost are the criteria of the choice of coating system. |
