4.5 Lacquering with LP/H lacquer and/or LP/H
lacquer antibac
By using the LP/H lacquer (REF 3062ff) or LP/H lacquer
antibac, you can protect hard earmolds due to an anti-
bacterial coating with high gloss effect
• First the part of the earmold that is to be processed
always has to be roughened with Corundum paper,
grit 180, (REF 40704).
• Then, fix the BTE earmold onto a piece of nylon tube
(REF 97200) and also fix the lacquering holder. With
an ITE earmold, the special Erkogum (REF 30911)
can be fixed to the opened battery valve.
• Then, clean and degrease the surface carefully by
using the provided hand-spray pump with a surface
cleaner (REF 31600ff).
• Apply the lacquer evenly. Alternatively, you can also
immerse the earmold (but no ITE device with an in-
built electronic or face-plates!) into a dipping jar filled
with lacquer (REF 31400 or 31401). Please mind to
shake off lacquer remnants.
• Then, let the lacquer cure in the egger light-curing
unit for about 2 – 4 minutes. The earmold can then
immediately be inserted.
For the processing, we recommend the egger lacquering
holder kit (REF 51207) as a useful accessory that consists
of magnetic lacquering holders (REF 51206), Erkogum
(REF 30911) and a nylon tube (REF 97200).
4.6 Lacquering with LP/W lacquer
For the surface finish the light-curing soft earmolds
(made of LP/W) are always lacquered with LP/W lac-
quer (REF 307ff). Furthermore, all presently known hard
acrylate-based otoplastic materials can be coated with
LP/W lacquer to improve the fitting of the earmold ("non-
skid coating").
• First the part of the otoplastic that is to be processed
always has to be roughened with Corundum paper,
grit 180, (REF 40704).
• Then, fix the BTE earmold onto a piece of nylon tube
(REF 97200) and also fix the lacquering holder. With
an ITE earmold, the special Erkogum can be fixed at
the opened battery valve.
• Then, clean and degrease the surface carefully by
using the provided hand-spray pump with a surface
cleaner (REF 31600ff).
• Apply evenly the lacquer and cure it for 4 – 5 minutes
in the light-curing unit.
• After the polymerization, the otoplastic (but no ITE
device with an built-in electronic – see separate note
below!) is post-cured with LP-Cleaner (REF 31300)
in the egger light-curing unit EL 1 for about 4 – 5
minutes. This is necessary to remove the inhibition
layer (sticky surface).
• Then, the otoplastic is rinsed under water and blown
dry.
!
ITE earmolds with an built-in electronic can be coa-
ted with LP/W lacquer, too. Please observe, however that
the otoplastic should not be put into the LP-cleaner bath!
To remove the inhibition layer you use a surface cleaner
moisted cloth and wipe off the surface thoroughly.
4.7 Modifications/Repairs with Modeling Pastes
The LP/H modeling pastes can be universally used for
various modifications and repairs with all kinds of hard
UV-curing polymerizates or acrylates. These are available
in the colors transparent, beige, red and blue.
• First the part of the otoplastic that is to be processed
always has to be roughened with Corundum paper,
grit 180, (REF 40704).
• Then, clean and degrease the surface of the otoplas-
tic carefully with Surface Cleaner (REF 31600).
