| Résumé : |
With the implementation of stringent environmental regulations for the reduction of Volatile Organic Compound (VOC) all across the globe, the need for waterborne paint system have never been so vital. Diverging from a common belief that water borne coatings are inferior to that of solvent borne in terms of various properties, the current era has started to witness the emergence of water borne Polyurethane Dispersions (PUDs). A fully fledged study is carried out in regard to PUDs, its various types like non-ionic, anionic and cationic, relevance of Segmentai variances like hard and soft segments, acrylic modifications and also sustainable modifications using oil, fatty acids and polyethylene terephthalate (PET) wastes. The study is not circumscribed by just traditional synthesis routes but also discusses in detail the current and even the bright future of polyurethane dispersions. PUDs are the areas with immense research scope and new technologies and methods are sure to be innovated, nevertheless, it carries in itself assured repercussions into the near future of the paint and coating industry. |
