Résumé : |
Because of their low cost and good compatibility with a wide variety of other polymers, alkyd based coatings are used in a large variety of applications. However, to improve their performance, the alkyd resins can be blended with ketonic resins. Such blends were analysed by SEM, and tested for their shelf life. Improvements in properties such as drying time, hardness, adhesion, flexibility, gloss, skinning tendency, impact resistance and chemical resistance were studied. |
