| Résumé : |
Coating industry significantly contributes to the carbon footprint and VOC (Volatile organic compound) considering high volumes of coatings are still solvent borne. Recent technological trends of the coating industry are showing sustainability as the key approach to achieve reduced carbon footprint and low VOC. This is also driven by various eco-friendly & green initiatives across the globe. This article emphasises the use of water as replacement for organic solvents during the manufacture and application of coatings. Of late many water based technologies have emerged as against solvent based system in the coating industry. Here resin / paint need to be designed in such a way to achieve dilution with water during manufacture and application in order to minimize any hazard, odour and VOC during the entire chain of paint processing and its use. Since polymers are most vital ingredient responsible for the performance of a coating system, it becomes imperative to make them water thinnable in place of organic solvent while ensuring acceptable performance as expected from them. Therefore, in this article, different formulation techniques and principles have been reviewed for water based polymer synthesis. Polymers can be sustainable if synthesised from bio-derived raw materials. Various binders used in the coating industry and their respective bio based raw materials have also been covered in this review as use of bio derived polymers and water as carrier opens doors for sustainable growth in the coating industry. |
