Hi Temp - Investment Powder

Product Description:
Whip Mix Hi-Temp Investment Powder is 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, and 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.
