| Résumé : |
The alkyd coating market continues to face increasing challenges as government bodies and environmental agencies establish new volatile organic content (VOC) and regulatory restrictions. In many cases, reformulation is necessary to meet ow-VOC requirements, which may cause adverse effects in the final coating, such as slow dry times, increasingly complex formulations, and poor coating performance. Formulators can overcome such performance obstacles in sustainable coatings by using the proper high-performance catalyst (HPC). This unique technology can meet VOC requirements, outperform standard metal carboxylates across multiple resin platforms, and may eliminate the need for complex drier packages. |
