Résumé : |
Modified alkyd resins were produced by alcoholysis of soya bean oil with pentaerythritol followed by esterification with pentaerythritol and phthalic anhydride. Various catalysts with different contents, including LiOH, butyl tin oxide and dibutyl tin chloride, were used for alcoholysis and/or esterification reactions. The effect of the catalyst on the reduction of the process time of alkyds, and their physicochemical and film properties, were investigated and evaluated. The catalytic system LiOH 0.07% — dibutyl tin chloride 0.2% proved to be the best catalyst system followed by LiOH 0.07%. The coating film characteristics of two paints, formulated with selected alkyds, were measured and compared. |
