Emulsogen EPN range
Products from the Emulsogen ® EPN range serve as efficient emulsifiers
which reduce the grit level during polymerization and improve dis -
persion properties such as freeze-thaw stability, electrolyte resistance
and sheer stability. They are suitable for emulsion polymerization of
olefinic monomers or vinyl acetate together with other vinyl esters,
Emulsogen LCN range
Emulsogen ® LCN is a preferred surfactant in various application fields,
such as emulsion polymerization, coatings, adhesives, construction
and detergents. Specifically, as emulsifier for emulsion polymerization,
Emulsogen ® LCN improves the shear, temperature and electrolyte stability
of polymer dispersions. At the same time, it can be used in inverse
emulsion polymerization of water soluble monomers in hydrocarbons
and in emulsions of oils, fats, silicon oils, polyolefin waxes, alkyd resins,
acrylates, vinyl chloride and ethylene, in acrylic and styrene/acrylic
dispersions as well as in butadiene/styrene latex. Emulsogen ® EPN
also finds widespread use in pigment preparations, paints and coatings
as a dispersing and wetting agent.

mineral oils etc. As a medium foaming wetting agent in aqueous solutions,
emulsions, architectural paints, industrial and wood coatings,
Emulsogen ® LCN reduces the surface tension of the aqueous medium
and improves the wetting of hard surfaces. It is an efficient dispersing
and wetting agent in aqueous pigment preparations and can be added
to emulsion paints to improve the scrub resistance.
