5. PREPARE CASTING
Finish and polish metal casting in a
usual manner. GC METALPRIMER II is a metal adhesive
primer with monomer containing
thiophosphoric metacrylate (MEPS).
Note: GC METALPRIMER II is very
volatile. Replace bottle cap
immediately after use.
6. FOUNDATION OPAQUE (FO)
Note: Remove any Opaque remaining
on nozzle syringe tip with tissue
paper.
- For best results, light cure Opaques
with GC LABOLIGHT LV-III: see chart
1 above
- Refer to curing depth of
Opaque chart on page 28.
7. MARGIN OPAQUE (MO) 8. OPAQUE (O)
For deeper, richer cervical colours,
apply MARGIN OPAQUE in 1 mm
width cervically using a round
brush. MARGIN OPAQUE, if applied after
Opaque layer of the tooth shade,
may create a whitish line showing
through final composite layer. To entire surface, apply two thin coats
of OPAQUE (O) using a flat brush.
Avoid to use a too thick layer, the
curing process might turn out to be
insufficient.

Remove beads within 0,5 mm from
margin area with a carbide bur. Sandblast metal surface that requires
application of GC METALPRIMER II
with clean 50μ aluminium oxide. Blow surface with clean, dry
air and immediately apply
GC METALPRIMER II.
Note: There will be no change in
surface look after coating.
Apply GC METALPRIMER II, one or twice
by using a clean brush. Allow drying for
a few seconds.
Immediately start to apply FOUNDATION
OPAQUE to avoid contamination of the
bonding surface.
FOUNDATION OPAQUE shade serves
as foundation of all shades.
Dispense FOUNDATION OPAQUE
into disposable pallet and shield with
light protective cover. Apply layer of FOUNDATION
OPAQUE about 100μ thickness with
flat brush.
Note: If Opaque gets too thick, stir
with brush to restore fluidity.
