word,” he said. “TPO growth has not been
hindered by the low surface energy of the
polypropylene component, as many pre-
treatment methods have been developed
and implemented to ensure continual
strong adhesion.”
In his presentation, Yaneff discussed
various changes that have occurred
over the years to ensure successful com-
mercialization of TPO, including water-
borne coatings for plastics. “There will
be a global transition to low bake in
North America,” said Yaneff. “This will
help meet environmental regulations,
stronger adhesion requirements and
more severe test methods for TPO.
Changes are still occurring today and
are still developing to ensure highly
durable parties will continue to meet
OEM needs and requirements.”
Other papers presented included “The
Use of Aqueous Pre-Dispersed Fumed
Silica to Improve Film Formation in
Waterborne Coatings,” presented by
Matthew Linares of Evonik Degussa
Corp. Fumed silica in pre-dispersed,
aqueous form offers not only ease of
addition, but has demonstrated the abil-
ity to enhance multiple attributes in
waterborne coatings, according to
Linares. “One of the most interesting
attributes enhanced by using these dis-
persions is improved film formation,” he
said. His presentation focused on a
study conducted by the University of
Minnesota to determine the mechanism
behind the improvements in film forma-
tion observed with fumed silica disper-
sions in various latex systems. The
study showed the improvement of film
formation is due to reduction of cracking
and lowering of minimum film forming
temperature caused by the reinforcing
nature of fumed silica. “Other attributes
that can be enhanced by using fumed
silica dispersions are anti-settling,
improved sag resistance, reductions of
film tack, improved dirt pickup resist-
ance and anti-cracking in highly filled
systems,” he said.
“2K Waterborne Polyurethane Technology for Automotive Clearcoats
Application” was presented by Philippe
Barbeau of Perstorp, France. “Over the
years, polyurethane systems have been
used to a growing extent in a number of
industrial application fields,” said
The Symposium featured 25 papers on a variety of topics related to “Advances in
Sustainable Coatings Technology.
Barbeau. “This success comes from their
outstanding properties, such as high sol-
vent and mechanical resistance, very
good adhesion onto various substrates,
fast film formation and excellent weath-
ering resistance, which make them ideal
candidates for high demanding and high
performance coating applications.”
In addition to the main technical pro-
gram, the Waterborne Symposium fea-
tured a Student Poster Session and two-
day Technology Showcase consisting of
fifteen tabletop technical exhibits,
including displays from Air Products,
Cognis, Evonik and Perstorp.
The Symposium concluded with an
awards ceremony honoring the best
papers and student poster. The USM
Best Student Poster Awards were pre-
sented to undergraduate and graduate
students. First place for undergraduate
went to Emily Hoff for “Biomimetric
Lipid Membranes for the Study of
Membrane Surface Structure.” First
place for the graduate student poster
was awarded to Ryan Hensarling for
“‘Clicking’ Polymer Brushes Using Thiol-
Yne Chemistry: Indoors and Out.” The
Outstanding Paper Award was given to
Jung Kwon Oh of the Dow Chemical
Company for “High Throughput
Methods for Developing Low VOC
Waterborne Coatings Derived from
Polyurethane Dispersions Based on
Natural Oil Polyols.” The Shelby F.
Thames Best Paper Award was present-
ed to Edwin Chan of the National
Institute of Standards and Technology,
Polymers Division for “Harnessing
Surface Wrinkling to Measure the
Viscoelastic Properties of Polymer Films
and Coatings.”
Next year’s Symposium will be held at
the Astor Crowne Plaza, March 2-4. CW
