Standard ITO Glass 4 ohms per square and 12 Ohms per Square
Standard
Thickness 1.1mm
The
soda lime float glass is coated with a primary layer of
Silicone Oxide (SiO2) and secondary layer of Indium Tin
Oxide (ITO).
Surface Resistance:-
4 or
12 ohms per square
Coating Thickness:-
150nm
Heat Resistance:-
300 °C for 30 minutes
Humidity (60°C/90%
RH) . No effect
Adhesion to glass:- MIL M-13508 4.4.6
Abrasion Resistance:- MIL C-675-A 4.6.11
MIL E-12397-B
Transmittance at 550nm:-
89%

For
polished ITO glass, the roughness is about 1nm.
For
un-polished ITO glass, the surface roughness is about
2nm.
The
average RMS roughness of ITO is 1~2nm.
Termination
Method
Direct
contact can be made to the conductive surface by
suitable conductive fabric
over
foam gasket, silver loaded silicone gasket, copper tape
or silver epoxy painted
bus
bar. Do not use gaskets containing metal which can
damage the coating or place
the
window directly against a hard plastic or metal surface

EMI-ITO windows are either un-laminated or fully
laminated glass filters with various
ITO coatings
of between 5 and 500 ohms per square. Windows are available to order
as
finished windows.
Our laminated versions offer greater
strength and options for front surface treatment
and edge
profiles.

ITO Coatings
Visiontek
Systems Ltd offers a range of ITO coatings for EMC, anti
static and heater window applications. Our ITO coatings
can be applied to polycarbonate, acrylic, glass
and
a range of transparent films. The coating resistance can
vary between 10 ohms
per
square to 1000 ohms per square depending on the
application. Quotations are available for specific
applications
Flex-Shield
15 Conductive Film
Flex-Shield
is a vacuum deposited multi-layer coating on flexible
clear polyester film. It
is
available on 175 micron thick polyester and in a
conductivity of 10 to 15 ohms/square,
The coating is optically neutral and have high visible
light transmittance. Flex-Shield
15 has visible light
transmittance of > 74%
Flex-Shield
is stable in humid environments, showing a resistivity
change of only 1%
when exposed to 24h 95% RH at 49 deg
C, and good thermal stability to 80 deg C ,
resistance change of 2% after 72 hours at 80 deg
C.
The minimum
bend radius of the product is 3mm but somewhat higher if
the conductive coating is on the outside of the bend.
Flex-Shield
is available in sheet form, as die cut shapes or as
rolls up to 1.2 m wide and 1000m long. Flex-Shield
can also be supplied with the additional options of a
peelable protective film on both faces and an optically
clear pressure sensitive adhesive on the
non-conductive
face.
Although
Flex-Shield has been developed for the EMC Shielding
market other applications include:-
Touch
Panels, Membrane Switches and Transparent Heating
Elements.
