| Résumé : |
This research centered on discovering individual relationships between formulation variables and the coating's performance. Variations in properties related to changes in catalyst, crosslinker, pigment, and an additive were studied using controlled stress rheometry, dynamic mechanical analysis, and tensile tests. A statistical design combining the elements of both a screening design and a response surface design significantly reduced experimental time, while fulfilling a broad array of experimental objectives. Among other things, this work revealed that the coatings were incompletely cured under typical bake conditions, the catalyst had the strongest influence on properties, and pigmentation reduced the performance properties. The results of this work led to significant improvements in the products performance and cost. |
