Furane
Based Furachem Cement
This is an
intimate mixture of liquid resinous
material and a powder composed
of suitably selected filler usually
containing the required setting
agent.This is a non-porous, self
hardening and relatively plastic
in nature.When set and cooled
a dense impermeable cement is
obtained.It is designed to use
as a bonding cement for Acid Proof
Brick lining in Tanks, Vessels,
Floor, Drains etc.
This cement provides resistance
to most of the inorganic and organic
acid(upto pH-3) with the exception
of strong oxidising acid, such
as, Cromic Acid and nitric acid.This
also provides excellent resistance
to a wide range of alkalies(upto
pH-11), solvents(both aeromatic
and aliphatic), salt solution
etc.Industrially this cement finds
wide application in gas scrubber,
flue gas duct due to its resistance
to wet gases. |

CNSL
Modified Phenolic Based Cashewchem
Cement
This is an
intimate mixture of liquid resinous
material and a powder composed
of suitably selected filler usually
containing the required setting
agent. This is a non-porous, self
hardening and relarively plastic
in nature. When set and cooled
a dense impermeable cement is
obtained.It is designed to use
as a bonding cement for Acid Proof
Brick / Tile lining in Tanks,
Vessels , Floor and Drain etc.
This cement provides resistant
to a wide range of non oxidising
acids, alkalies, mixed solution
but not recommended for use with
aliphatic and aeromatic hydrocarbons.
It can also with- stand to a reasonable
extent oixidising acids such as
Chromic Acid and Nitric Acid.
When filled with graphite it is
resistant to Hydrofluoric Acid.
The special formulation providies
ecellent protecion against mixture
of HF and HNO2 in the
pickling of Stainless Steel and
alloy steels. |
