Emulsogen® 4084

Emulsogen® 4084 by Clariant 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. It 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, it forms a clear aqueous solution in a concentration of 25% and below. More concentrated aqueous solutions of Emulsogen® 4084 become waxy at room temperature. It can be used in combination with other non-ionic, anionic and cationic surfactants. 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.
