We produces a wide range of optically clear (ITO PET) Indium Tin Oxide coated transparent, conductive film products.
ITO PET products are produced by vacuum sputter deposition of ITO, a process that affords excellent coating uniformity and adhesion.
All standard our ITO PET products are produced on optical grade polyester film. By special order ITO coatings are available on other film
substrates, for example, heat stabalised film, anti glare film, or clear hard coated polyester film. Also by special order, we offer ITO coatings
with a surface resistance that is higher than that of standard ITO PET products.

| Electrical Uniformity |
|
All products feature electrical uniformity of 10% within any one square foot
area, defined as the maximum difference from the average ohms per
square value within that area. However, touch screen manufacturers
typically achieve < 1% resistance linearity by orienting their sensors
(busbars) so that the electrical current path is always in the direction
of the length of the film roll.
|
| Handling |
|
Vacuum deposited ITO coatings are very thin and are easily scratched or cracked if handled improperly. When removing film from a roll, care should be
taken not to bend or crease it. It is important never to allow the ITO coated side to come in contact with a surface, such as a table, during processing
operations. Sliding ITO coating over a surface will scratch the coating, resulting in elevated surface resistance and visible defects.
Please note that all ITO PET film product supplied in sheet form is supplied with protective liner on all surfaces.
