This comprehensive text covers all aspects of retention of fines and fillers. Written by a team of industry experts, it is divided into four main sections: an introduction; mechanics and retention; chemistry and retention; and pigments and retention. Specific topics include retention in a neutral alkaline papermaking system and pigments for retention, including titanium dioxide and talc.

From the Preface: “...I hope that this book will be a guide to those who have to make decisions as to what pigments to use; what chemistry to use and why one would want to use a particular combination of chemistry and pigments for the production of a given paper...”

Target Audience: Marketing, development, and sales personnel in the chemical industries that supply paper manufactureres; researchers, technologists, purchasing specialists, and others in the paper industry and educational programs concerned with the retention of fines and fillers.
