SuperVest
Fine Grain, Carbon Free, Phosphate Bonded Investment
Technique Instructions
Powder to Liquid
SuperVest is suitable for both ring and ringless casting systems. This investment is specifically designed for all types of metal alloys and therefore dilution is required. Total volume of solution used is as follows: 60 gm -> 14.5 cc and 90 gm -> 21.5 cc. Depending on the alloy you use, you should dilute the special liquid by following the recommended ratio.

To increase expansion, use more special liquid and less water. To get less expansion, use less special liquid and more water. Keep the total volume of the solution constant. If you cannot get enough expansion, order SuperVest High Expansion Liquid (Blue Color).

Mixing and Investing
For best results, liquid and powder should be between 70-78°F. Incorporate powder into liquid and hand spatulate for 10-15 seconds. Vacuum mix for 90-120 seconds and then vibrate and break vacuum. Vibrate the investment into the casting ring using a brush to fill critical areas before filling ring. Bench set for 45-60 minutes for normal burnout. Bench set for 15-25 minutes for fast burnout.
