| Résumé : |
Titanium dioxide is the brightest, whitest pigment available. TiO2 is one of the most widely used pigments in paint, plastics, textiles, cosmetics, and paper industries.' It efficiently scatters visible light thereby imparting whiteness, brightness and opacity to paint and coating material. The cost of TiO2is increasing steadily and thus the cost of paint with minimum operational margin. The partial replacement of the TiO2 Pigment with the use of less expensive subsidiary product will give some cost advantage. In the present scenario high performance coatings are most widely used to preserve industrial equipment, pipelines, plant and buildings from deterioration by exposure to water, chemicals or weather which find application in automotive, industries and industrial structures, iron, steel and concrete structure, ships and marine structures, reactors, pipelines, machinery components etc. The present work emphasises on the partial replacement of TiO2pigment with Calcium Aluminum Silicate (CAS) and Magnesium Aluminum Silicate (MAS) in high performance coating application without affecting the quality of coating. Different performance coatings were prepared with partial replacement of TiO2 with CAS & MAS and analyzed for important optical properties like opacity, whiteness, Gloss and brightness. The mechanical properties were also evaluated for these coatings. The CAS & MAS fillers showed potential of replacing 5 - 30% by weight of TiO2 in different types of performance coatings. |
