Özet

Different types of minerals in varying amounts are used in paint formulations depending on the paint characteristic. While titanium dioxide (TiO2) is used as a main pigment to improve the paint properties, some minerals such as calcite and calcined kaolin are used as a filler to decrease the cost of the paint, and in some cases as a substitute for TiO2. An important criterion for developing paint formula, especially for architectural ones, is to load maximum amounts of mineral pigments or fillers as much as possible to satisfy the rheology of the paint. Appropriate type and amount of dispersants is crucial at this stage to get the proper fiowability at high amount of pigment and fillers.
