BASF is presenting its new generation of binders for
architectural coatings at this year's European Coatings
(April 26 - 28). COL.9® is a high-tech product combining inorganic and organic
chemistry. BASF researchers already won the 2004 Coatings Award (Farbe-und-Lack-Preis)
for developing this innovation, and COL.9® DS 1000 has now become the first
commercially available product in this specialty segment for outdoor applications.
In the new COL.9® binders, inorganic nanoparticles are homogeneously incorporated
into organic polymer particles of water-based dispersions. The resulting nanocomposite
dispersions combine the benefits of inorganic binders – such as hardness and
permeability – with those of organic binders – such as elasticity and water
COL.9® DS 1000 was developed specially for façade coatings. After
application and drying, the inorganic nanoparticles form a homogeneous three-dimensional
network structure covering the entire coating film. Because of this extremely
fine nanostructure, facade coatings based on this innovative technology are
extremely resistant to dirt and chalking (separation of white pigments), do
not crack, and display high color tone stability. The lattice structure composed
of inorganic and organic components is furthermore responsible for its excellent
fire behavior properties. The color film does not melt in the presence of fire
and does not drip.
"Our new generation of binders creates the basis for new, significantly better
performing facade coatings," says Ralph Schweens, head of BASF's Business Unit
Adhesives and Construction Industry Europe. "It makes exterior paint jobs better
able to withstand tough weather conditions. Not having to repaint so often is
a hands-on benefit for the consumer – especially since the facade keeps that
freshly painted look for longer". It's also why BASF chose to market the new
binders using the slogan Anti-aging for facades .
As a leading supplier of products for the construction industry, BASF develops,
produces and markets polymer dispersions worldwide. They are used for the production
of textured finishes, finishing systems and compounds, advanced super plasticizer,
roof coatings or ceramic tile adhesives for example. In paints and architectural
coatings they are used as binders. BASF's strengths include its efficient research
and development and global application technology. The business is part of
the Functional Polymers division within BASF's performance products segment.
