| Abstract: | A high solid and low viscosity alkyd resin was firstly synthesized using fatty acid, polybasic acid and polyhydric alcohol as raw materials. This alkyd resin was modified by esterification reaction using acrylic monomer in order to prepare acrylic modified alkyd resin and its coatings with high glass transition temperature, low VOC content and high solid. The various influencing factors on performance of the modified resin and coatings were discussed. The experimental results showed that the obtained coatings have the performance of quick-drying at low temperature and no sagging at thick coating. |
