The 2-K-DOS and 2-K-MiniDOS
mixing and dispensing devices
can process polyurethane and
epoxy casting compounds with
viscosities up to around 20.000
mPas at room temperature.
Casting compounds, particularly
epoxy and polyurethane, develop
lower viscosities at higher
temperatures. An increase in
temperature of 10° C reduces
the viscosity by approximately a
factor of 2. The THERMO-DOS
heating option reduces the
viscosity to such an extent that
it is possible to process casting
compounds with viscosities up
to approximately 80,000 mPas.
For casting compounds that can
be dispensed at room temperature
but that flow poorly or too
slowly into the parts to be sealed,
the heating reduces the viscosity
to such an extent that
such compounds can be processed
more quickly during
sealing and the compounds can
also flow into narrow gaps in the
parts that are to be sealed.
With the THERMO-DOS option,
the two material containers, the
pumps, the dispensing hose and
the dispensing head are heated.
The modules are heated individually
with temperature control.
The temperature is adjusted
centrally at the heating control
unit. If more heating is required
for large material containers, a
heating sleeve can additionally
be placed around the container.
A heater is also available for the
mixing nozzle. This ensures that
the casting compound is always
available in a heated and lowviscosity
form at the mixing
nozzle without a lead time, even
after a device standstill or
interruption in the sealing work.
