| Résumé : |
Many challenges face today's coatings formulators. Some of these challenges involve removing cost from a coating formulation or improving performance but many are related to producing coatings with improved environmental profiles. Lowering volatile organic compound (VOC) levels in architectural and industrial coatings is a chief concern in many new product development and reformulation projects. Balancing good performance and low VOC is critical, as a low-VOC coating with poor performance is of little value. Coatings formulators and end-users are provided with several technology options to address the desire for lower VOC including the use of solventborne coatings with high solids or VOC-exempt solvents (such as acetone or t-butylacetate), powder coatings, and waterborne technologies. Waterborne acrylic latex technology, in particular, offers a number of advantages such as low toxicity, lower risk of fire from handling flammable solvents, easy one-component use, easy and safe cleanup with water, and less hazardous disposal. However, many latex coatings still utilize a significant level of coalescing solvents to aid in film formation, so the challenge of going to even lower VOC levels is still present in many applications currently using or moving towards waterborne latex coatings. |
