Conditioning the metal surfaces with
SR Link or SR Chroma Link
Version 1: SR Link
Application of SR Link
After the framework has been sandblasted (Al
2 O 3 /
100 microns/2 bar) and cleaned of blasting residue by
tapping it off, SR Link is applied. Apply SR Link with a clean
disposable brush and allow it to react for 3 minutes.
Do not apply SR Link on alloys containing more
than 50% silver and/or copper or on alloys
containing more than 90% gold, palladium or
platinum.
Non-precious metal and titanium alloys require mechanical
retention to provide a long-lasting bond.
Mechanical retention is generally advantageous to
improving the bond between the framework and veneer.
Application of SR Chroma Link
After you have sandblasted (Al
2
O
3
/100 microns/2 bar) the
framework and cleaned it of blasting residue by tapping it
off, apply a thin coat of SR Chroma Link on the blasted
metal surface. Subsequently, leave to evaporate for 3 to
4 minutes. The opaquer is applied immediately after the
evaporation time.
If SR Chroma Link is used, retention beads must be
applied onto all types of metal frameworks
(precious metal, non-precious metal, or titanium).
Apply a thin coat of SR Chroma Link, using a disposable brush.
Version 2: SR Chroma Link
Apply SR Link.
