| Résumé : |
Global concerns of environmental pollution and greenhouse gas (GHG) emission has led growing legislative stringency to be more tightened in present scenario. Increased consumer/user awareness towards green and sustainable chemistry is a demanding factor for major coatings and raw material suppliers to direct their efforts, either in the area of reformulating their existing product formulations or adopt new approaches to meet the requirements. Architectural coatings occupy around 55% portion of the total global coating consumption. Ultra low and Zero VOC coatings with low odor are the need of the hour for sustaining the business as well as future of the coating industry. This review article highlights the progress in the area of designing green architectural coatings with special focus on water based paints including the processing and chemistry of emulsion polymers viz. acrylics, VeoVa, EVA and waterborne alkyd technology for glossy finishes. Some critical paint ingredients which are major contributors of VOC like coalescing aids, rheology modifiers, surfactants and other additives are also being addressed with reference to legislative aspects. Further alternatives over depleting petro-products such as biochemicals (bio- monomers) and renewable sources of raw materials to ensure sustainability are discussed. |
