| Résumé : |
Over the past decade, the interest in gloss emulsion paints has been growing, driven by environment-friendly and fire hazard-free nature of the product coupled with its low-odour, quicker drying and easy clean-up. This product seeks to be an alternative to the conventional alkyd based synthetic enamel. This is still a distant goal. Development of a gloss emulsion paint is fraught with many technical issues. The inherent nature of the emulsion polymer requires a trade-off between the film formation capability and performance properties of the film. Poor gloss development results from the inferior flow-out due to rapid coalescence, inefficient pigment wetting and shrinkage. The water sensitivity, low solids and low film build are the other issues to be addressed. The optimization of the technical parameters is further to be balanced with the cost of the product. These challenges are sought to be met by deep exploration of the film formation process and the interactive influence of various components like film former, pigment, thickener and the other additives. Some options are also available for the pigment dispersion process. |
