| Résumé : |
Flexibility in the functional design of acrylic powder coatings has enabled a wide range of different crosslinking chemistries to be developed, based upon carboxyl, hydroxyl, and glycidyl functional binders. The use of dynamic viscosity/time (temperature) cure curves is seen as a powerful technique to quantify formulation and resin design parameters. This paper describes how the technique can be used to highlight differences in the available crosslinking chemistries and begins to show how this can be used to predict coating performance on a more quantitative level. A simple model describing the viscosity changes during the curing process is presented, which shows good qualitative agreement with the experimental results. |
