This outstanding phosphate
investment has these advantages:
• Contains carbon for bright, gold-
colored castings.
• Expansion can be controlled to t
your needs – yet technique is easy
to follow.
• Even, extremely thin sections will be
cast with sharp, clean margins just
like lower-fusing golds.
• Accurately tting castings with
smooth and clean surfaces –
without grinding. Uniform results
time after time.
The chart below shows the effective
expansion gures obtainable
by varying the concentration of
Special Liquid Concentrate. A 75%
concentration, three parts Special
Liquid concentrate and one part water,
is generally preferred. Thermal and
also setting expansion will increase
by greater Special Liquid Concentrate
concentration; these expansions will
decrease by dilution with more water.
Consequently, expansion can be
controlled to t individual needs.
There is no additional thermal
expansion between 700° C and
1,000° C (1,300°F and 1,800° F).
The curve in the chart shows dif ferent
gures for the thermal expansion
merely as a result from higher or
lower con centration of Special Liquid
Concentrate. The setting expansion
for a benchset mold is shown in the
lowest curve.
