Silicone Resins and their Combinations
From Author :
Because of their molecular structure, silicone resins and silicone combination resins are used in numerous industrial applications, particularly as binders, for formulating coatings. The linking of silicon and oxygen atoms to form a stable basic framework, in which the free valencies of the silicon are saturated by hydrocarbon groups, results in outstanding properties which cannot be achieved with other products. The many possible combinations of the silicone building blocks are reflected in the impressive diversity of silicone chemistry and the resultant products.
The present book (2nd edition) is intended to provide a concentrated overview of the chemistry and technology of silicone resins and their use from an industrial viewpoint. It aims to report on current developments in the field of silicones for coatings and gives those approaching the subject an overview of the most important areas of application. Since publication of the 1st edition of this book almost ten years ago, some areas of application have seen further technological developments and these have driven significant advances.
For example, silicone combination resins are being increasingly used in anticorrosion coatings to cope with extreme weather conditions and temperatures. Alkoxy-silyl functional urethane resins are used in high-tech coatings to increase scratch resistance.
New types of acrylic dispersions in combination with functional polysiloxanes enable the formulation of “below-critical” emulsion coatings with similar properties to “above-critical” silicone resin coatings.
These and further innovations are described in the 2nd edition of this book and reflect the current state of the art in this field.
Since this field will continue to develop, I am pleased that I have been able to win my colleague Dr. Sascha Herrwerth to join me as co-author for this new edition. I would like to thank our colleagues Dr. Michael Ferenz, Dirk Hinzmann and Dr. Berendjan de Gans for numerous technical discussions. Thanks are also due to Evonik for making available company literature and permission to reprint extracts as well as for technical and material resources.
