A special investment for non-precious
and semi-precious alloys, Hi-Temp
contains no carbon.
Non-precious metal alloys require an
investment specially compounded to:
• Compensate for alloy shrinkage
• Withstand high-fusing temperatures
• Provide a non-contaminating
atmosphere
• Allow casting of a lighter-density
metal
Hi-Temp is the investment with these
characteristics and more. It gives a
smooth surface to the casting, ows
readily and evenly for ne detail and
sharp margins, and has high strength
to prevent damage to the mold.
The technique is simple. Special
Liquid Concentrate is used instead
of water. Control of expansion is
obtained by dilution of the Special
Liquid Concentrate with water – the
greater the dilution, the less the
expansion of the investment. Four
parts liquid to one part water is the
proportion suggested to get some
frictional retention for full crowns on
well-tapered preparation. Otherwise,
the technique is essentially the same
as handling any casting investment.
The chart below shows the various
expansions of Hi-Temp at different
concentrations of Special Liquid
Concentrate.
