4.5 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 trans-
parent, beige, red and blue.
• 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, clean and degrease the surface carefully by using the provided hand-spray
pump with a surface cleaner.
• Directly apply the modeling paste out of the tube by means of a modeling instrument
(REF 31215) and smooth the transitions to the ground .
• Then, depending on the coating thickness applied, let it cure for about 2 – 4 minutes
in the light unit egger EL 4.
• After the polymerization of the surface, wipe off the otoplastic by using a surface
cleaner moisted cloth.
• If required, rework the otoplastic with a cutter and prepare it for lacquering as de-
scribed in 4.3/4.4..
