| Aluminium
Silicate having the general formula Al2SiO3,
is remarkable for its use as filler and antisettling agent in
paint and as semi reinforcing agent in rubber. It can be manufactured
either by precipitation or by processing of the naturally occuring
aluminium silicate minerals. The precipitated variety gives
better properties due to smaller particle sizes and higher white
strength value. |
| MANUFACTURING
PROCESS |
| |
| Aluminium
Silicate is first precipitated in large tanks. It is then
filtered and washed dried and micronized on most modern
plant to prevent contamination. Our R&D department
has developed the precipitation process to provide accurate
control of particle size and surface area. The properties
have been optimized in our different grades according
to the application. |

| ADVANTAGES
OF OUR PRODUCTS IN PAINTS |
| |
|
| a. |
Part
of white pigment like Titanium-dioxide
(10% or more) can be replaced without
loss of opacity. |
| b. |
Give
faster surface and through-drying in
product which also stand up better to
abrasive treatment. |
| c. |
Excellent
substrates for high gloss finishes as
they ensure good levelling out. |
| d. |
Act
as anti-setting agents for pigments
and fillers. The viscosity of decorative
paints containing our product is highly
constant over extended periods of time.
Being basic, they also have positive
effect on storage stability. |
| e. |
Give
excellent thicksotropy and facilitate
dripless application. |
|
|
|
The
particles of the filler used interact with
the polymer, thus changing the properties
of the mix and vulcanized material. For a
filler with definite chemical composition,
this interaction becomes more intensive as
the surface area of the filler particles increases.Due
to fine micronization of our products, they
have very large surface area and thus give
excellent properties in terms of tensile strength,
modulus and resistance to tear and abrasion.
They are particularly suitable for soling
and microcellular sheets as they give relatively
fast cures and enable production of soling
materials to be streamlined. |
