The RDS drying systems are used predominantly
for drying and hardening lacquers, adhesives
and casting compounds. Not only do they ope-
rate reliably and eciently, they also offer indivi-
dual solutions for specic elds of industry.
From sensitive applications in semiconductors
through to a complete conformal coating line
with built-in dispenser for the precise application
and drying of coating lacquers – we’re happy
to advise you on the individual possibilities
and system congurations we can implement
for your special requirements. The RDS drying
systems are flexible and offer sufcient scope
to execute applications from the most diverse of

Protective lacquer coatings increase the reliability and
service life of your products. They enhance the tracking
resistance of your components and provide protection
against environmental inuences such as moisture,
corrosion, chemicals and dust. Casting compounds reduce
mechanical stress, for example vibrations on the component.
These materials need to be hardened reliably so that they
can later work without any problems in end devices in the
automotive industry, medical technology or security-related
modules in aerospace technology. The lacquer determines
the process! Depending on the coating material, convection
(i.e. moving warm air) is used in the drying process, or infrared
radiation as an addition in the combination heating process
for particularly flexible proling. In the process, temperatures
up to a maximum of 250 °C are used for optimum hardening
of the components, depending on the product and process
requirements.

Lacquer and casting hardening
To achieve the best drying results, it is important to precisely
coordinate the process and material. We differentiate between
physically hardening lacquers, which harden very quickly pure-
ly with the release of solvents, oxidative-hardening lacquers,
which dry with atmospheric oxygen, chemically hardening
lacquers, often 2K materials and radiation-hardening
lacquers which harden with UV radiation, for example. A
separate UV dryer is required for the latter. The RDS systems
are perfect for hardening polyurethane resin, acrylic resin,
epoxy resins, acrylate resins and silicone-based casting
compounds.
A slow heating of the assembly is essential, particularly
when it comes to protective coatings that contain volatile
solvents, because an excessively high temperature gradient
during the heating phase can cause the top layer of the
coating to harden too quickly and the underlying solvent
will no longer be able to escape. For this reason, the drying
systems from Rehm Thermal Systems feature two short
zones at the inlet area which are regulated separately in
order to provide the optimum temperature gradient for the
corresponding paint.
