Axalta and TAU Industrial
Robotics shed light on curing
Insight and control into the coating process for electrical
steel in e-mobility and renewable energy electric machines
Users of Voltatex®
insulating materials from
Axalta, a leading global
supplier of liquid and
powder coatings, can now
exclusively have access
to the newly-developed
LILIT® (Light In-Line
Insulation Test) to monitor
and document the drying
consistency of the coatings
produced.
LILIT is a product of Italian technology
company TAU Industrial Robotics. It provides
reliable and accurate test methodology of
functional polymers, such as those used as
synthetic resins in coatings. The test ensures
the coatings maximise their full quality
potential at the optimum degree of
polymerisation. High-performance technical
machines such as electrical motors require
accurate and comprehensive quality control
of the ideal curing of insulating materials
during the manufacturing process.
Modern composite technologies including
self-bonding processes for the production of
electric motors for e-mobility are particularly
sensitive. These require superlative quality
control in order to pass the high demands
on reliability and cost efficiency.
Before the development
of LILIT, polymerisation
processes could not
be monitored and
documented adequately.
A non-contact, non-
destructive in-line test
method for coil coating
– as standard in the
electrical steel coating
process – was not
technically feasible.
Christoph Lomoschitz,
Global Product Manager
for Axalta’s Energy
Solutions business, says,
“We can now do away
with time-consuming
quality checks at the
beginning and at the
end of the coated coil
process. These didn’t
bring much information

about the degree of polymerisation because
of local fluctuations in drying conditions
across the entire coated coil. So by bringing
TAU’s LILIT technology to our customers,
we are making their quality control much
better and more efficient, as well as
improving process accuracy and overall
electrical steel quality.”
Filippo Veglia, Chief Commercial Officer
TAU Industrial Robotics, says, “We are
committed to bringing higher performance,
improved sustainability, and meaningful
insight to the core functions of e-mobility
and renewable energy. We are thrilled to
work with Axalta to bring real-time, non-
contact, in-line quality control of curing
processes to the electrical steel industry.”
Axalta is exhibiting the full range of its
Energy Solutions products at the Coil
Winding Expo (CWIEME) in Berlin, Germany,
from 21 to 23 May 2019 on stand A19,
Hall 3.2. Visitors will have the opportunity
to see a demonstration of the new LILIT
technology and discuss with TAU on stand.
