Résumé : |
Titanium Dioxide is a multifaceted material in coating applications. It efficiently scatters visible light thereby imparting whiteness, brightness and opacity to paint and coating material. The cost of TiO2 is increasingsteadily and thus the cost of paint with minimum operational margin. There are two ways to stabilize this rise in cost, one is to lower the quality of paint by less use of essential ingredients and another way is to use the subsidiary product in the replacement of the primary product either cent percent replacement or partial replacement which gives some cost advantages.
This work is related to partially replacement of TiO2 pigment with calcium aluminum silicate and magnesium aluminum silicate in non aqueous and aqueous paints respectively with negligible effect on the quality of paint. The cent percent replacement of TiO2 is impossible and an attempt is made to replace it partially with cost benefit without affecting whiteness, brightness and opacity of paint. Both the extender pigments showed potential of replacing TiO2 in different type of coatings ranging from 5% to 18% by weight depending on the desired end properties. |
