WHIP MIX - HI TEMP
C&B High Heat Investment
# 119586 - Mfg # 00671
Features:
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
* It gives a smooth surface to the casting, flows readily and evenly for fine 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.
Suggested concentration of SPECIAL LIQUID CONCENTRATE is 75% (3 parts liquid to 1 part water).
