SURFYNOL® MD20 MOLECULAR DEFOAMER
– A NEW DEFOAMER FOR COATINGS, GRAPHIC ARTS AND
ADHESIVES APPLICATIONS
16 January 2004 — response to demand
for higher performing defoamers for new compliant
water-based coating, ink and adhesive technologies,
Air Products has introduced a new product based on
Gemini surfactant technology: Surfynol® MD20 molecular
defoamer.
Surfynol MD-20 molecular defoamer offers the ability
to reduce the surface tension of water, enabling better
wetting of surfaces. Its unique combination of foam
control and dynamic wetting offers benefits for many
types of water-based applications. In addition, Surfynol
MD-20 molecular defoamer has the potential to reduce
overall additive levels leading to simpler, more economic
formulations.
Traditional defoamers rely on incompatibility to
provide foam control, but this leads to difficulties
of incorporation and surface defect formation. Molecular
defoamers provide an answer to these problems.
Molecular defoamers based on Gemini surfactant technology
are very surface active and break foam at a molecular
level. They destroy ionic and other forces which can
stabilise foam, causing the foam to collapse. These
silicone-free molecular defoamers also offer long-
term activity compared to systems which operate by
incompatibility.
Foam produced during manufacturing, mixing or application,
can be controlled by Surfynol MD20 Molecular Defoamer.
When used alone, or in combination with other surfactants,
Surfynol MD-20 Molecular Defoamer is particularly
effective at eliminating micro-foam and other foam
related coating defects.
Surfynol MD-20 Molecular Defoamer finds use in: automotive
OEM and refinish, wood coatings, industrial maintenance
coatings and architectural coatings, as well as graphic
arts and adhesives applications. Surfynol MD20 Molecular
Defoamer has been shown to be particularly effective
in water-based systems. The benefits to formulators
