| Résumé : |
Formulators face drying and hardness challenges with high-solids resins, which this research seeks to resolve. Using an alternative drier and anti-skinning agent to comply with regulations can negatively impact a coating's drying properties. However, researchers have found a promising combination for successful curing and hardness development. |
