Calcium
Stearate "CEMPROTECT"
– An Introduction
Calcium Stearate "CEMPROTECT" is a product developed by Shrihari Laboratories (P) Ltd, Kota. It is an
outcome of rigorous efforts and continuous
Research & Development. This product has been
developed by technical experts working in the
cement paint industries.
Calcium Stearate "CEMPROTECT" is a free flowing superfine white powder, having
highly water repelling properties and is most
suitable for cement paint formulation.
Calcium Stearate
"CEMPROTECT" is a special grade of
waterproofing compound for cement paint
formulation which protects the coating from water
penetration and thus enhances the long term
durability in cement paint coatings. Ordinary
Calcium Stearate may impart waterproofing
property to some extent, but may not give long
term durability. In fact, Calcium Stearate is an important component of the formulation of the
Cement Paint which protects the coating.
Functions
of Calcium Stearate "CEMPROTECT"
1. "CEMPROTECT"
being highest pure and fine grade, helps in coating
each and every particle of cement and other
extender materials.
2. Coated particles do
not come in contact with water or moisture due to
high repellency by "CEMPROTECT".
3. "CEMPROTECT"
highly protects the
coating of cement paint from moisture
penetration. The life of cement paint coating is
reduced considerably if not protected from
moisture. The penetrated moisture invites
bacteria and thus due to germicidal action there
is algae and fungal growth. This phenomenon
weakens the coating and thus either coating comes
out in the form of flakes or converts into black
moss.
4. As "CEMPROTECT" coats each and
every particle of cement paint so the coating
becomes water tight. This property of water
tightness does not allow moisture/water to
penetrate inside the film and hence germicidal
action does not take place.
Three
exclusive features of "CEMPROTECT"
Properties of
"CEMPROTECT" can be
explained by 3 P’s - Prevention,
Protection and Preservation.
Prevention : The water
repellency properties of "CEMPROTECT" -
- Prevents powdered cement paint from hardening and thus the problem
of lump/granule formation is not observed during
storage.
- Always keeps the
material fresh and thus no deterioration in
quality takes place.
- Imparts better
shelf-life.
- Prevents the coating
from de-adhesion.
Protection : Use of
"CEMPROTECT" –
- Protects the cement paint coating from moisture penetration and thus
no algae or fungal growth takes place.
- Increases water
tightness and thus life of cement paint coating.
- Improves brushability.
- Imparts smooth and
uniform consistency to wet mix of cement paint.
Preservation : The pot-life
of wet mix of cement paint is increased
considerably by use of "CEMPROTECT". The shelf life
is also increased to a great extent.
Comparison
of "CEMPROTECT"
and Stearic Acid
Many cement paint
manufacturers use Stearic Acid for
water-proofing. The characteristics of both and
their advantages and disadvantages when used in
cement paint are compared in following table:-
"CEMPROTECT"
|
Stearic
Acid
|
| Pure
White in color with assured color
consistency. |
Light
brownish to dark brown in color. Color
also varies from lot to lot. |
| Superfine
Powder. Mixes easily with cement and other ingredients. Calcium Stearate "CEMPROTECT " is a Calcium
based product like other cem raw materials e.g. Calcium Chloride, Calcium Hydroxide (Hydrated Lime) etc. and is , therefore, compatible with Cement which
is also Calcium based. |
Available in flakes form. Proper mixing does not take place. Moreover Stearic Acid is non
Calcium based and un-compatible with
Cement. |
| Coats each and every particle of powdered
material. The coating is performed just
by simple mixing at room temperature. |
Coating
takes place only by vapourising action on
a relatively high temperature. There is always a risk of "no vapour
formation" till ball mill is heated sufficiently and temperature is raised
above the melting point of Stearic Acid. This results into high residual content,
which is largely un-reacted Stearic Acid. |
| No
chances of de-adhesion. |
Oil contents in Stearic Acid may cause de-adhesion of cement paint coating. |
| No
interference in pigment dispersion. |
Interferes in pigment dispersion , so pigment
dispersion takes a very long time. |
| Cement
paint coating remains water repellant for
a very long time. |
Over a period of time, water repellency in cement
paint coating is lost. |
Packing
25 Kg Polythene Lined HDPE Bags. Liners are specially stitched to outer HDPE Bags from inside bottom. This prevents liner
from falling down itself with material in the
ball mills.
Recommended
Dosage
We recommend a dosage of
0.5% to 2% for extremely effective results.
