Silane coupling agents are excellent adhesion promoters for dissimilar substrates. They have been used for decades to modify surfaces, fillers and binders in the coatings, glass and composites industries. This unique ability of silanes to act as a bridge comes from the structure R'-(CH2)n-Si(OR)3 where the silicon end of the molecule binds to a suitable substrate while the R group can either bind to the medium or provide a compatible environment for the bonding to take place.
Specific examples of adhesion promotion achieved by using silane coupling agents on different surfaces will be presented during this webinar. Advanced silane known as dipodalsilanes which are represented by the general strucutre (RO)3Si-(CH2)n-R'-(CH2)n -R-Si(OR)3 will also be discussed along with specific application examples. Dipodalsilanes, with twice as many hydrolyzablealkoxy groups as conventional silanes, form denser interfacial layers and stronger structures above the interface through the formation of highly crosslinked siloxane networks. Apart from being used as adhesion promoters, silane coupling agents have found applications in corrosion resistance, durability of coatings, as rheology modifiers and anti-fog applications which will be discussed during the course of the webinar

Professor Janis Matsions, Gelest Inc.
Professor Matisons is currently the Senior Research Manager at Gelest Inc. He previously held a personal Chair in Nanotechnology at Flinders University, becoming the first professorial appointment in nanotechnology in Australia at that time. He has been involved in applied chemical research since 1976 specializing in materials, polymer and silicon-based research over the last two decades. This interest brought him to the USA and Gelest Inc. in 2011, where he is now the Senior R&D Manager. He was the Chief and Founding Editor of the new journal, Silicon Chemistry (since retiring from this editorial position, the journal is now called Silicon), and has published close to 400 scientific articles/conference and technical papers. In 2008 he became the editor of a new book series "Advances in Silicon Science" by Springer. He was on the editorial boards of Journal of Adhesion Science and Technology, Journal of Polymer Research, Polymer International and Chemistry in Australia.
He has participated in 28 industry-academic collaborative grants, resulting in over two dozen patents, the formation of three spin off companies, and the launch of 79 products into the global marketplace. The first spin of company, Flexichem has now grown to be Australia's largest silicon materials manufacturer. As director of the Polymer Science Group at the University of South Australia, he saw the group grow to become Australia's largest polymer research group in 2001, having directed the successful implementation of over 16.4 million dollars of research funding over the previous 8 years. Funding has come from not only Australian companies, but multinationals based in the USA, Europe and Japan. He moved to Flinders University as Chair of Nanotechnoogy to pursue his research interests in nanotechnology, where he directed a new and growing group. His research interests have covered a broad spectrum of research disciplines; from the awarding of the William Culross prize for his early research in organometallic chemistry at Adelaide University, to the Royal Australian Chemical Institute's Polymer Citation for excellence in silicon research and education.
Professor Matisons has organized several international and national meetings, the most recent ones being the silicon materials symposium in the Pacific Polymer Federation meeting in Cairns in 2009, the 16th ISOS International Silicon Symposium in Hamilton, Canada in 2011 the ICTAC (International Conference on Thermal Analysis & Calorimetry) in Orlando Florida (August 2016).
