Emulsogen EPN 287
NONIONIC EMULSIFIER FOR EMULSION POLYMERIZATION
Emulsogen EPN 287 is used as nonionic emulsifier for the emulsion polymerization of monomers like acrylates, styrene-acrylates, styrene-butadiene and vinyl acetate.
Emulsogen EPN 287 by Clariant is an APEO-free, low VOC (less than 1%) oxoalcohol polyethylene glycol ether with 28 mole ethylene oxide (fatty alcohol polyglycol ether).
Acts as a wetting- and dispersing agent. This clear, colorless liquid is inherently biodegradable and soluble in water.
Emulsogen EPN 287 is suitable for label-free pigment preparations, paints and coatings complying with 21 C.F.R US FDA regulations. It is listed in AICS, EINECS, DSL, ENCS, IECSC, KECI, NECI, NZloC, PICCS and TSCA.
Emulsogen EPN 287 is used in polymerization of vinyl acetate together with other vinyl esters, acrylates, vinyl chloride and ethylene, for acrylic and styrene/acrylic dispersions and for butadiene / styrene latex.
The use of Emulsogen EPN 287 reduces coagulation and improves electrolyte resistance and freeze/thaw stability. Emulsogen EPN 287 is added either during or after polymerization.
Storage and Shelf Life: Please keep the product in a dry and clean place. Emulsogen EPN 287 tends to form a gel phase and separates below 15°C.
After heating to 30 – 60°C the precipitates dissolve again. Please mix well and homogenize the product before use. 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 : No preservative is added.
Safety : Please see Material Safety Data Sheet before handling the material.
The use of Emulsogen EPN 287 offers the following advantages:
free of alkylphenol ethoxylates (APEO)
hazard label free
easy to handle
Performance in emulsion polymerization:
maintains low viscosity of polymer emulsion at different shear rates
enhanced electrolyte stability
improved shelf life (high freeze thaw stability)
