Lacquering with LP/H lacquer antibac

By using the LP/H lacquer antibac (REF 3062ff), you can protect hard earmolds due to an an-
tibacterial coating with high gloss effect
• First of all, the part of the otoplastic that is to be processed has always to be rough-
ened with Corund paper, grit 180, (REF 40700).
• Then, fix the BTE earmold onto a piece of nylon tube (REF 97200) and also fix the lac-
quering holder. With an ITE earmold, the special Ergokum 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 316ff).
• Apply evenly the lacquer. 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 unit EL 4 for about 2 minutes. The earmold
can then immediately be inserted.

Lacquering with LP/W lacquer

For the surface finish the light-curing soft earmolds (made of LP/W) are always lacquered with
LP/W lacquer (REF 307ff). Furthermore, all at present known hard acrylate-based otoplastic
materials can be coated with LP/W lacquer to improve the fitting of the earmold ("non-skid
coating").
• First of all, the part of the otoplastic that is to be processed has always to be rough-
ened with Corund paper, grit 180, (REF 40700).
• Then, fix the BTE earmold onto a piece of nylon tube (REF 97200) and also fix the lac-
quering holder. With an ITE earmold, the special Ergokum 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 316ff).
• Apply evenly the lacquer and cure it for 2 minutes in the light unit.
• After the polymerization, the otoplastic (but no ITE device with an in-built electronic –
see separate note below!) is afterpolymerized in the egger light unit EL 4
for about 2 – 4 minutes. This is necessary to remove the inhibition layer (sticky surface).
• Then, the otoplastic is rinsed under water and blow dryed.
ITE earmolds with an inbuilt electronic can be coated 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.
