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 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.
EMULSOGEN EPN 287 is listed in AICS, EINECS, DSL, ENCS, IECSC, KECI, NECI, NZloC, PICCS and TSCA.
Uses of EMULSOGEN EPN 287:
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.
Benefits of EMULSOGEN EPN 287:
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).
Storage and Shelf Life of EMULSOGEN EPN 287:
Please keep EMULSOGEN EPN 287 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 EMULSOGEN EPN 287 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 EMULSOGEN EPN 287 should be analyzed for extension of the shelf life.
Preservation of EMULSOGEN EPN 287:
No preservative is added.
Safety of EMULSOGEN EPN 287:
Please see Material Safety Data Sheet before handling the material.
