Coating offers a wide temperature range and
helps mitigate field installation failures
The Micro-Measurements® brand of Vishay Precision Group, Inc.
(NYSE: VPG) (www.micro-measurements.com), industry experts in the
design, development, and manufacture of resistive-foil sensors for
high-precision strain, high-stress and force mechanism
measurements, today introduced the Gagekote #1, an expansion of the
Gagekote Series, a solvent-thinned (toluene) synthetic resin. The
Gagekote #1 is ideal for applications in PCB testing, agriculture,
civil engineering, automotive, stress analysis
aviation/defense/aerospace, education, medical, Internet of Things
(IOT), Robotics, Industry 4.0, consumer, Process monitoring, load
cell manufacturer. Transportation, Energy, and smart manufacturing
industries.

The Gagekote #1, often used as a pre-coat for Gagekote #5 and
Epoxylite #813, is resistant to moisture, and offers a
wide-operating temperature range that is easily removable after
exposure to temperatures as high as 500F. It was designed to
provide maximum stability of the strain gage sensor, as moisture is
the most common cause of field installation failures.
“A good protective coating such as the Gagekote #1 not only
seals the strain gage installation from moisture, but also seals in
any moisture in the area at the time of coating application,” said
Yuval Hernik, Sr. Director of Sales and Marketing. “In order to
provide maximum stability in high-moisture environments, the gage
installation should be warmed until all moisture is removed prior
to applying the protective coating. Next, the Gagekote #1 coating
should be immediately applied after gage and leadwire installation
to prevent moisture from collecting in the gage area. One of the
advantages of the Gagekote #1, is that it provides a wide
temperature range coating and can easily be removed after exposure
to temperatures as high as 500F.” (260°C)
Field installation of strain gages present stress analysts with
several unique challenges, particularly when long-term measurements
are required, and when massive structures or inclement weather are
encountered. For example, strain gage sensor performance is easily
degraded by the effects of moisture, chemical attack, or mechanical
damage. As a result, strain gage sensors require varying degrees of
protection, according to the severity of the environment in which
they must operate. The Gagekote #1 provides maximum stability of
the strain gage sensor through its protective coating that is
immediately chemically stable and highly resistant to water-vapor
transmission. The coating only protects against incidental
mechanical damage, like minor objects lightly coming into contact
with the installation, or very lightly dragging across it.
