A pressure sensitive spacer coating for a touch screen may include a silicone adhesive material dissolved in a solvent. A touch screen may also include a first layer including a first conductive coating, a second layer including a second conductive coating, and a silicone pressure sensitive adhesive disposed between the first layer and the second layer. A method of manufacturing a touch screen may include providing a first layer having a first translucent conductive surface. The method may also include providing a second layer having a second translucent conductive surface. The method may also include applying an adhesive solution including silicone on at least one of the first conductive surface and the second conductive surface. The touch screen can be an analog or a matrix resistive touch screen. The adhesive can be applied by screen printing. The adhesive can be mixed with a slow evaporating solvent before screen printing.
