CHROMECAST-40 is a phosphate-bonded
high-heat investment specially developed to cast partials
in chrome-cobalt alloys. The models are made using special
liquid to control expansion and provide a harder smoother
model. The investing can be done by using water only or by
using a small amount of special liquid to give the mold higher
burnout strength and higher thermal expansion for added expansion
control.
A finer grain material, it offers
the following outstanding properties:
- A creamier mix
- Long working time
- Elimination of bubbles on the
castings
- More stable expansion characteristics
with higher thermal expansion
- Fast burnout at high temperature
in preheated ovens
- Excellent consistency from batch
to batch
It can also be used for other castings in gold, palladium,
platinum, and non-precious alloys when it is used with special
liquid. The selective use of the special liquid provides controlled
expansion required for other applications such as crown &
bridge castings.
