Copolymerizable Emulsifiers<br />
Classic anionic and non-ionic emulsifiers stabilize <strong>the</strong> emulsion by<br />
physical interaction. However, <strong>the</strong>se surfactants desorb at high shear<br />
<strong>for</strong>ces or because of electrolytes which <strong>the</strong>n in turn leads to coagulation<br />
of <strong>the</strong> latex particles.<br />
In order to avoid migration and nest <strong>for</strong>mation in <strong>the</strong> polymer film,<br />
Nonionic copolymerizable emulsifiers<br />
Anionic copolymerizable emulsifiers<br />
Clariant has developed a range of copolymerizable emulsifiers, which<br />
chemically bond to <strong>the</strong> polymer, inhibiting migration in <strong>the</strong> film and<br />
resulting in higher latex stability. Additionally, freeze-thaw stability<br />
and shear stability are significantly improved. The products are also<br />
less water absorbant and enable hydrophobic coating surfaces.<br />
