Although care has to be taken in its application, it is more hardwearing than the standard liquid crystal sheets and can be cut to size and used to create a touch sensitive colour changing graphic that allows interaction by touch to whatever flat surface it is applied to. The sheets are constructed from a vinyl film with polycarbonate (Lexan) overlaminate. The colour change properties of the LC coating are viewed through the clear overlaminate. The sheets are supplied backed with pressure-sensitive adhesive and, on removal of the protective backing, can be adhered to a variety of flat surfaces. Black Changes to the Visible Spectrum of Colour When Touched. Touch Temperature Sensitive Colour Change 77 to 86ºF (25 to 30ºC) Dimensions 223 x 204mm Vinyl film with polyester over laminate, adhesive backed with protective backing Total Thickness: With adhesive: 175-225 microns. Colour Change: Black to the visible spectrum (red, green, blue) with increasing temperature, and finally to black again. Tolerance: Start of color change temperatures ±2ºC; bandwidth of color change temperatures ±2ºC For adhering the sheets to flat surfaces, the following simple steps should be followed: Clean surface thoroughly to remove all dirt, grease, etc. Chloroform, petroleum ether and similar organic solvents may be used. Ensure that the surface is completely dry before proceeding. Remove protective backing from adhesive and place sheet lightly in position on surface. Press down firmly with fingers in center of sheet and smooth outward, in each direction in turn, to ensure that no air bubbles are trapped between the sheet and the surface. Sheets can be cleaned using a soft cloth and warm soapy water. Do not use abrasive material or aggressive solvents. Unused sheets should be stored out of direct sunlight at room temperature (20-25oC (68-77oF)), and preferably in a solvent-free environment. Sheets should be protected from UV light and organic solvents wherever possible.
