X-20 Chrome Investment

X-20 Chrome Investment is a Phosphate Investment for Casting Partials with Chromium Dental Alloys

X-20 Chrome Investment is a vastly improved casting investment for making chrome partial denture frameworks.

For casting any chrome partial alloy

Refractory Cast is hard, strong and smooth

No danger of breakage or abrasion

Fits master models like gold castings

Sets fast -- no tamping required

Controlled expansion with SPECIAL LIQUID CONCENTRATE

May be used without metal ring

Mixes easily and produces a cast of unusual smoothness and strength. May be used with any good duplicating material intended for chrome investments. A SPECIAL LIQUID CONCENTRATE is furnished for pouring the 'working cast.' A 1 to 1 dilution with water gives controlled expansion for most alloys. If more expansion is desired, dilute with less water such as 2 parts liquid to 1 water. Water only is used in mixing the investment for the outer mold or ,ring. Castings are usually made with burn-outs between 730 degrees C and 1,000 degrees C (1,350 degrees F and 1,800 degrees F) although X-20 may be heated to 1,100 degrees C (2,000 degrees F) if required.

* Recommended Concentration of SPECIAL LIQUID for X-20 Chrome Investment is 50% (1 part liquid to 1 part water).

*Recommended Liquid - Special Liquid Concentrate
