Covering both current technology and the future prognosis for the key additives used in water-borne coatings today, this title brings together international expertise to provide a comprehensive, practical overview of the field, its direction, and selection of key additives currently employed for in-depth treatment of their use, behaviour and scope by expert practitioners in those additives. The publication includes two plenary chapters reviewing the developments together with the regulatory and legislative scene in the overall field. It also contains seven in-depth chapters devoted to key additive types, specifically: rheology modifiers, matting agents, surface active agents, dispersants, defoamers and biocides. In addition, the book provides: a systematic approach to additive selection and additive rules - for the development of a coating; a good understanding of the biocidal degradation effects and the key biocide strengths and weaknesses in addressing them; a thorough understanding of silica-based matting agents and their mode of action; and useful overviews of water-borne dispersants, silicone surface active agents and cellulosic and associative thickener rheology modifiers.
