Résumé : |
Cellulosic thickeners have been used as Industry Workhorse for thickening latex paints, since many years. However, latex paints thickened with cellulosics could not provide paint films, which are richer in looks and have high aesthetic appeal. Continuous research in order to overcome these deficiencies in cellulosics, led to the evolution of new generation thickeners termed as Associative Thickeners. These thickeners have out-performed cellulosics in many aspects and have been well accepted by the industry. Various aspects which resulted in changing the trend from use of cellulosic to associative thickeners are reviewed in this paper. Also, factors governing the performance of the above thickeners and latex paints based on them are discussed at length. |
