Foam-inhibiting wetting agent
Modified polyalkylene glycol
When used in emulsion paints, DEHYDRAN 240, on
account of its chemical structure, offers a number of
advantages, such as:
improvement of stability,
stability against temperature fluctuations,
easier dispersion of pigments,
lower water absorption, improved resistance against water marks,
improvement of flow and film properties.
DEHYDRAN 240 is used as a foam-inhibiting wetting
agent in the manufacture of emulsion paints and
other polymer emulsions. It can also be used as a
defoamer in printing pastes (for textile printing) and
in glues applied in printing plants. Furthermore,
DEHYDRAN 240 may also serve as an ingredient in
the manufacture of anti-foaming agents for
numerous fields of application.
DEHYDRAN 240 can be used in conjunction with
Dehydran C, F, G or appropriate other defoamers. It
is particularly effective in emulsion paints containing
finely dispersed acrylic or polyvinyl acetate
homopolymers or copolymers as binding agents.
When manufacturing emulsion paints it is advisable
to add DEHYDRAN 240 to the pigment paste
together with Dehydran C, F, G or appropriate other
defoamers. An addition to the unpigmented polymer
emulsion is also possible.
DEHYDRAN 240 can be used undiluted. With water
instable emulsions can be achieved.
DEHYDRAN 240 is insensitive to acids and lyes.
The amount required depends on the intended
application and must be determined in each case by
appropriate tests. In emulsion paints it is generally
between 0.5 and 2.5%, calculated on the total
formula.
