Suitable for craft modeling use, adhesive, may be coloured with pigments, heating at 100°C sets the material to a permanent shape, at 1500°C the material hardens into a ceramic.
About
What is the problem? A number of modelling clays and user formable adhesive materials such as Blue Tack are already available. However these materials are limited to one specific use. Our new Solution Our workers have developed a material which combines the best properties of modern modeling materials formable adhesives, and traditional clays. Benefits of the new technology Suitable for craft modeling use, adhesive, may be coloured with pigments, heating at around 100oC sets the material to a permanent shape, sintering at 1500oC transforms the material to a hard dense and strong ceramic. Background Ceramic Tack was synthesised using a combination of ceramic and polymeric processing. The room temperature properties of the Ceramic Tack are similar to the popular adhesive Blue Tack. Unlike Blue Tack, the physical, chemical and mechanical properties of ceramic tack are highly affected by temperature. As a result, it can be used for a wide range of application. Ceramic-Tack exhibits very interesting properties which can be used for multipurpose application. At room temperature, ceramic tack is a putty-like pressure-sensitive reusable adhesive. It behaves as a rigid shape at low stress but can flow in the same way as a liquid at high stress. Ceramic-Tack can be classified as a Bingham like material because it flows and moulds when pressure is applied but sets when you stop moulding it. As a result, the material can be used for stationery applications around the home, office or school. It could be used to hold notes and objects in place or temporarily stop leaks. In addition, it is easy to use to form shapes either in a mould or by hand to create sculptures. Shapes have been created with a feature size of less than 75 micro meters. Ceramic Tack polymerizes and cross-links at temperature ranges of 50˚C-150˚C for 10-30 minutes (or in a700 watt domestic microwave). The putty-like pressure-sensitive properties are diminished and the material turns into a permanent solid form. If the temperature is increased to between 1200˚C and 1700˚C, in a furnace, sintering occurs. The material transforms into extremely hard dense ceramic product. Mass loss after sintering is about 2-8 % depending on the temperature. The product has potential use in art and craft as a material for production of high temperature net shape parts for industrial applications.
