EMULSOGEN 4084 used as nonionic emulsifier for the emulsion polymerization of monomers like pure acrylic, styrene-acrylic acid esters and vinyl acetate.
EMULSOGEN 4084 is used in emulsion polymerization of polyvinyl acetate, acrylate and styrene/acrylate dispersions to stabilize the rheological behavior of the polymer dispersions and to improve the electrolyte and shear stability.
EMULSOGEN 4084 is a non-ionic, APEO-free, low VOC (less than 1%) ethylene oxide (EO)-propylene oxide (PO) block copolymer with an ABA structure consisting of 60 wt% ethylene oxide units.
The A block is hydrophilic and the centered B block is hydrophobic.
Acts as an emulsifier.
Exhibits low foaming and offers good wetting & dispersing properties.
EMULSOGEN 4084 stabilizes the rheological behavior of the polymer dispersions and improves the electrolyte & shear stability.
Is resistant to water, hardness salts, acids and alkalis in the concentrations normally used.
This pale yellow wax needs to be melted at 60°C and added in parts to hot water (95°C) under stirring until the solution becomes clear.
At 25°C, EMULSOGEN 4084 forms a clear aqueous solution in a concentration of 25% and below.
More concentrated aqueous solutions of EMULSOGEN 4084 become waxy at room temperature.
EMULSOGEN 4084 can be used in combination with other non-ionic, anionic and cationic surfactants.
EMULSOGEN 4084 is used in emulsion polymerization of polyvinyl acetate, acrylate and styrene/acrylate dispersions.
Complies with FDA regulations and is listed in AICS, DSL, EINECS, ENCS, IECSC, NECI, KECI, NZloC, PICCS and TSCA.
