Pigmentation pigments and paint making

The outline formula of a paint has been given in Chapter 7 and the nature of polymers and resins has been described in Chapter 5. In the next three chapters, the other main ingredients of surface coatings will be covered briefly, before particular paints are described in the remainder of this book. 

A detailed study of the chemistry of pigments is beyond the scope of an introductory book such as this and is already available elsewhere (see Appendix A). Instead, this chapter reviews some of the key properties of pigments and discusses their selection and methods of incorporating them into paint. 

Any surface coating pigment will need to carry out some (or perhaps, all) of the following tasks  

To choose a pigment to carry out a given selection of these nine functions, we must know about the following properties of the pigment  

The phrase tinting strength is sometimes applied to white pigments. A single coloured pigment is used for the comparison of white pigments at a fixed shade.
