Silanes
SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 667.9 Revêtements et enduits Résumé : Increasing the durability of organic coatings for architectural applications using silicon-based materials was presented at MECS 2006 by the author.
Silicone modification of organic resins is a proven method of improving the weather resistance of paints for exterior applications. The organic resin provides the basic properties of the coating such as film forming, cure mechanism and chemical resistance. These properties are often achieved at the expense of resistance to UV radiation over a range to temperature and humidity conditions. This is where silicones can plug the gap in the property profile. Concern for the environment and the health of coating users is driving the coatings industry to develop high solids and waterborne versions of paints for exterior surfaces. In this paper we hope to have demonstrated some ways of utilising the benefits of silicone resins and intermediates in these increasingly important delivery forms.Note de contenu : - Silicone intermediates for organic resin modification

Although the weathering of organic materials has long been acknowlelged, it was only in the '50s, with the widespread use of polymeric materials in our everyday life, the the detrimental effect of light became a serious concern to engineers of the plastic industry. It appeared that two main approaches could be considered to address the problem: consider weathering as a global process affecting the functional properties of a material or approach weathering as a range of chemical reactions at the molecular level accounting for the loss of the service life properties.Note de contenu : - One field, two approaches

Newt yers (2007) will mark important anniversaries for a number of key events in the history of the idea of sustainability: it will be 20 years since the publication of the Brundtland report ('Our common future'); 15 years since the Earth Summit in Rio and 10 years since the Kyoto Protocol was signed - all events which have had a significant effect on global public opinion. Neither business nor individuals can afford to ignore environmental issues any longer. The sustainability trend is driven by society's changing values, with consumers demanding that industry acts more reponsability and governments around the world introducing increasingly strict legislation to ensure it does so. International paint and coatings manufacturers are among the companies that have to comply with stricter environmental regulations, while at the same time improving product performance and meeting the requirements of consumers. Unfortunately, the environmentally friendly solutions, which could help them achieve this, are often suspected of veing less effective in terms of performance and cost - a major concern when it comes to surfactants, as the reliability and performance of these substances is essential. However, Cognis' new generation of environmentally friendly surfactants firmly refutes this prejudice. The surfactant system Disponil AFX is an example of how an environmentally conscious approach can bring market success when it does not have an adverse effect on product performance. The product range recently received official recognition from the Federation of German Industries (BDI), in the shape of the organisation's Environment Award.Note de contenu : - Regulatory compliance - the key challenge for surfactants

Polyéther de siliconeIndex. décimale : 667.9 Revêtements et enduits Résumé : Food packaging regulations could severely limit material choice for the ink and varnish industry.
The rules and regulations for the use of printing inks and over print varnishes in contact with food severely limit the choice of materials available to printing inks and varnish formulators for food packaging applications. With expertise in modifying the archecture of silicone-polyeter copolymer technology, we are able to design structures to achieve good foam control and film quality in the manufacture and application of waterborne inks and varnishes, whilst most importantly allows compliance to food packaging legislation in place to protect the public.Note de contenu : - Structure of silicone-polyether copolymers
