Tyzor® ET is the most reactive organic titanate in the Tyzor® product line. It has a very high titanium dioxide content and will rapidly decompose in the presence of water. Tyzor® ET is most commonly used as a cross linking agent where it will bind with polymers containing hydroxyl or carboxyl functionality. Metals and glass can be treated with Tyzor® ET to improve adhesion, surface hardness, and heat & light reflection. Polymeric films of titanium dioxide can be formed on glass and ceramic surfaces with Tyzor® ET by using sol-gel processes. Tyzor® ET is also an effective moisture scavenger because of it's high water sensitivity. It can be used to prevent moisture contamination in formulations that are particularly sensitive to water. As a metal catalyst, Tyzor® ET acts as a Lewis acid to improve yield while eliminating unwanted by-products. It is best suited for use in the synthesis of polycarbonates in diethyl carbonate systems and as a replacement for organostannanes.
