Opis

This volume discusses latices in surface coatings in regards to emulsion paints. 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.

• Describes the principles of the formulation, manufacture and application properties of water-based 'emulsion' paints and related surface coatings
• Includes inter alia gloss and anti-corrosion paints and electrocoating

As 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.

The production of polymer latices has developed over the past half–century from pioneer status to a major industry with an annual production of over 6 million tonnes of polymers. Over this period, increased understanding of their many technical applications has extended the usefulness of water–based latices both technically and commercially. With present trends in ensuring environmental safety, water–based latices play an ever–increasing role, overcoming the limitations of water–soluble and solvent–based polymers in a diverse range of applications.

This title is one of a three volume set entitled The Applications of Synthetic Resin Latices, which discusses the preparation and application of specific groups of latices or polymer emulsions.

Volume 2 Latices in Surface Coatings: Emulsion Paints describes the principles of the formulation, manufacture and application properties of water–based ′emulsion′ paints and related surface coatings. Emulsion (architectural) paints, including industrial finishes, have, with adhesives, been a major field in the application of synthetic latices, therefore this volume has been devoted to this important topic. Developments including theoretical studies, film formation and in practical application, ambient cure, improved microbiocides, coatings for metal, and fire resistant coatings, are all covered in this volume. Topics such as electrodeposition and electroless deposition are included with industrial finishes.
