Profile
Use
Emulsogen® EPA 073 is an anionic surfactant for industrial applications like the following:
Emulsion Polymerization
Emulsogen® EPA 073 is used as an emulsifier for emulsion polymerization of monomers like styrene, acrylic acid esters, methacrylic acid esters and vinyl acetate. The use of
 Emulsogen® EPA 073 offers the following advantages:
— production of polymer dispersions with controlled particle size
— very low grit levels at high solid contents.
Usage levels: 0,5 – 5,0 % based on monomers.
Pigment Preparations
Emulsogen® EPA 073 is used as a wetting agent for inorganic and organic
pigments in preparations
— at high pigment loads
— at low viscosity
— high temperature stability and shelf life.
Usage levels: 15 – 80 % based on the pigments.
Emulsions of solvents, oils and waxes in water
Emulsogen® EPA 073 produces stable, low foaming emulsions of organic solvents, hydrocarbons, oils and waxes in water.
Usage levels: 1 – 20 g/l Emulsogen® EPA 073 in the emulsion.
Storage and Shelf Life
Please keep the product in a dry and clean place. When the product has cooled down to less than 5°C, please heat it up to 25°C – 30°C, after stirring it is ready
to use again. The shelf life is at least two years when stored in tightly closed containers at 20-25°C in a clean and aerated place. After this period the product
should be analyzed for extension of the shelf life.
Preservation
Product is containing 5 ppm a mixture of 5-Chloro-2-Methyl-2H-Isothiazol-3-one and 2-Methlyl-2H-Isothiazol-3-one (3:1)
