Coating offers a wide temperature range and helps mitigate field
installation failures
MALVERN, Pa.--(BUSINESS WIRE)--
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.

Gagekote #1, Moisture-Resistant Protective Coating from Micro-Measurements® (Photo: Business Wire)
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.
