For the paint technologist, the challenge of product formulation is to achieve the optimum product for the market within an agreed budget, while at the same time operating within raw material and manufacturing constraints. This demands a variety of approaches, depending on the scale of the project, which may range from the simple substitution of a raw material within an established formulation to the development of a totally new class of product using existing or new technology. Whatever the scale of the project, however, certain basic principles apply, and the aim of this book is to describe these clearly and comprehensively. It is intended for paint technologists and suppliers of ingredients to the paint industry.
