Mastic
Based Mastichem Compound
Application:
The compound
is laid hot by Trowel over the
primed surface to any desired
thickness and the surface gets
hardened as it cools.This surface
is now ready for use.

Silicate
Based Chemsil Cement
Chemsil
Cement is a silicate based cement.It
consists of powder and liquid.The
Mortar,which is prepared by
mixing the powder with the liquid,
sets be a combination of chemical
& physical action.This is the
only cement which successfully
resists attack from high concentrations
of all oxidising acids, with
the exception of hydrofluoric
acid.This cement is used for
setting and bonding of acid
proof bricks and tiles for the
construction of acid proof tank
linings,floor surface etc.Due
to its resistance to high temperature
it is also used for lining chimneys,
incinerators, roasters and other
high temperature equipments.
Our CHEMSIL Cements are two
types:
CHEMSIL - SS - Sodium Silicate
Based Cement
CHEMSIL - KS - Potassium Silicate

Phenolic
Based Phenachem Cement
| This offers
resistance to almost all non-oxidising
acids, acidic salts and organic
solvents as it renders.This
phenolic based Phenachem Cement
has an outstanding capacity
to resist Hydrofluoric Acid
when used with graphite filled
system.This cement provides
resistance to most of the inorganic
and organic acid with exception
of strong oxidizing acid, such
as Nitric Acid and Chromic Acid.This
may also withstand weak alkalies
and salt solution.Industrially,
it is a successful combative
against pickling solutions of
various nature. |
