(Synthetic
Homo Polymer and
Co-Polymer)
Emulsion is the core
element of any water
based paint. All
paints are
combinations of
pigments (colorant)
emulsions and water.
Along with three
ingredients –
several additives
are used in small
quantities. The
additives perform
several key
functions. The
additives are
generally wetting
agents, helping in
dispersion, anti
settling agent, body
agent, flow and
leveling additives,
driers, gloss
improvers and many
others.
Whenever we
manufacture emulsion
we are involved in a
long process of 9 to
10 hrs where a DM /
DI (Deminerlised)
water about 50% and
remaining raw
material Vinyl –
acetate monomer
about 35 to 40 % and
other chemicals such
as catalyst,
initiators,
surfactants, wetting
agent are added. The
reaction temperature
is about 75 to 80°.
As this process is
exothermic a small
initial heating will
helps in enhancing
reaction and
completion of
process, in
intermediate sample
testing and the
controlling the
temperature within
desired limit is
essential to get
excellent product. |
