Lettering work
Pic. 88 Lettering
HUMBAUR trailers and superstructures
are painted with air-drying 2K acrylic
lacquers.
The hardening of these lacquers
depends on the environmental
temperature and may take several
months at low temperatures.
The lacquers are not fully wear resistant
during this hardening time.
We therefore recommend to
avoid the use of high-pressure
cleaning devices or steam
nozzles for cleaning the trailer.
The following has to be considered
during lettering work to prevent damage
to the lacquer:
– Fresh paint coats must dry for at least
48 hours at +20 °C to be sufficiently
hardened, so that the auxiliary films
and tapes can subsequently be
pulled off without leaving markings on
the lacquer surface (do not use
corrosive adhesive films that form a
permanent connection with the
lacquer surface).
– Trailers that were already exposed to
humidity (snow, rain, fog) must be
dried in a temperature-controlled hall
(20 °C) for at least 24 hours before
any type of lettering is performed.
In icy weather, the drying period must
be extended until the trailer has
reached the temperature of the hall.
These processing guidelines and
instructions are not material-specific, but
apply in general.
