Oil sands
Oil sand GIBA S
Oil-Bound fine sand for moulding
Oil sand GIBA S is an oil-bound sand, is delivered ready for use
and cannot dry out because of its binding. Its high green strength allows
accurate shapes and exact castings.
Application:
Oil sand GIBA S is mainly used in Aluminium sector (light alloy sector)
and in art castings for thin parts.
Application instructions:
During application of the sand on the model, the first layer should be
sieved on and lightly pressed. Thereafter, the mold box can be filled
with sieved sand and has to be strongly compacted. Do not add water, do not use
any black washes.
Special features:
In addition to the standard quality, Oil sand GIBA S will be also
produced with higher fluidity (Oil sand GIBA SM) or less fluidity
(Oil sand GIBA S-fett). The Oil sand GIBA can not only be used as contact sand but also as
padding sand. (Used as contact-sand, it goes into the moulding
sand circuit. Used as a padding sand, it can be regenerated with
Oil and Paste.)
