This book covers the fundamental chemistry of latices and their applications in adhesives. These water-based latices are playing a far greater role in many applications and match the growing concern over environmental safety. This book is available separately or as part of a 3-volume set and offers an insight into the advances and developments in this field.* Introduces the principles and practice of emulsion polymerisation and of the resulting latices and their properties* Includes alkali-solubility, in relation to the requirements of specific applications, including pigmented systems and technical latices* Contains a comprehensive account of the formulation of latex-based adhesives for the bonding of many different substancesAs a comprehensive account of the science of polymer latices, these volumes are an invaluable resource for research workers and end-users in academia and industry working on water-based paints, adhesives, emulsions, dispersions and coatings.
