MIDLAND, MICHIGAN, USA – Low-maintenance coatings that deliver both
stain resistance and easy clean-up are becoming more popular in the
marketplace. They help reduce maintenance costs, protect the natural
appearance of substrates and are key to the development of specialized
coatings such as "anti-graffiti" paints and finishes. However, many of the
technologies available today find limited use due to their processing
requirements or poor performance and durability.
This April, at the European Coatings Show in Nürnberg, Germany, Dow Corning
will introduce a new easy clean, stay clean fluoropolymer technology solution
that removes these processing roadblocks.
According to Senior Development Specialist Dr. Peter Hupfield, the innovative
technology incorporates low levels of reactive organofunctional siloxane
(ROFS) into an isocyanate- or melamine-cured tetrafluoroethylene copolymer
(TFEC). The resulting material (TFEC/ROFS) exploits the synergy between these
compounds to help customers create a protective coating with excellent solvent
solubility that cures at room temperature and/or elevated temperature.
The development process of this technology is examined in detail in a paper
entitled Exploiting the Synergy of Fluorine and Silicone for Stain Resistant
and Easy-Clean Coatings. The paper will be presented during the show's
congress on Tuesday, April 26, from 9:30 to 10 a.m. at the Exhibition &
Convention Center in Nürnberg.
"This easy clean, stay clean coating technology solution provides superior,
cost-effective stain resistance, flexibility and durability," explained
Hupfield, who co-authored the paper. "Because it cures at room temperature
and/or elevated temperature, it is ideal for commercial and industrial use as
well as in specialty products such as anti-graffiti paints."
When tested against other coating systems, this new siloxane-enhanced
technology displayed excellent beading and dry-wipe removal of common staining
agents such as xylene marker, lacquer spray, red wine, urethane sealant,
iodine, coffee and carbon water. Formulations developed with easy clean, stay
clean coating technology can be sprayed or painted to a wide variety of
substrates such as stone, metal, glass, plastic, silicone rubber and paper.
HAPs- or VOC-compliant formulations are also available.
"Dow Corning is committed to giving our customers the innovative tools and
solutions they need to respond to new market demands"” Hupfield said. "This
coating technology is a real breakthrough that does just that."
