Additives are generally defined as components that are included in a coating formulation in relatively small amount; usually between 0.05 and 5.0% as a processing aid and to control, enhance or impart specific properties. Most of the additives perform a specific function. In recent years multi-purpose additives have been developed which reduce the number of additives used in a formulation. The selection of the right additive that compliments with other ingredients and the optimum quantity that should be incorporated in a formulation requires both theoretical as well practical considerations. This book compiles information on the types, properties, uses and performance of major classes of additives and should be of help to students, new entrants in the field as well as practicing professionals
