Transparent conductive coatings are very often used in electro-magnetic shielding, electrical heating, and cutting edge display applications. ZC&R uses the coating material indium-tin oxide (ITO) which provides for excellent durable coatings.
Often, ITO coatings are used in contact with materials other than air. ZC&R often designs and produces ITO coatings designed specifically to be used next to materials such as liquid crystal, cements, index oils, and various other materials. ITO coatings that have been under coated or overcoated to be index matched to a particular material, such as liquid crystal, can have very low reflectances.
One determining factor as to how low a reflectance can be achieved is the sheet resistivity specification. Thicker ITO layers yield lower sheet resistivities but also result in higher reflectances. Sheet resistivities as low as 5 to 10 ohms/SQ and as high as a few thousand ohms/SQ can be achieved. One common thickness of ITO, 100 angstroms, yields about 450 ohms/SQ.
ZC&R has a great deal of experience coating ITO and index matched ITO (IMITO) and we would be happy to review any particular requirements you may have. We would also be happy to be of assistance in exploring what specifications can be achieved using ITO.
