Cas: 9003-11-6, Genapol PF 80 P, NONIONIC EMULSIFIER FOR EMULSION POLYMERIZATION. Genapol PF 80 is used as nonionic emulsifier for the emulsion polymerization of monomers like acrylates,
styrene-acrylates and vinyl acetate. Genapol PF 80 is a pore-forming dispersant and plasticizer for plasters, mortars and putties based on cement, lime or gypsum
The use of Genapol PF 080 offers the following advantages:
free of alkylphenol ethoxylates (APEO)
hazard label free
Performance in emulsion polymerization:
maintains low viscosity of polymer emulsion at different shear rates
enhanced electrolyte stability
improved shelf life (high freeze thaw stability)
similar polymerization results to APEOs

Genapol PF 80 is a pore-forming dispersant and plasticizer for plasters, mortars and putties based on cement, lime or gypsum. Genapol PF 80 improves the processability, softness and surface smoothness of building materials. Dispersion of fine particles of mineral binders and pigments is ensured and the stickiness of plasters and solutions containing methylcellulose on the instrument is reduced.
With Genapol PF 80, lump formation in gypsum plasters is reduced and the processing time is significantly extended. Genapol PF 80 is compatible with all anionic and nonionic surfactants as well as Mecellose methylcelluloses. The formation of air pores with Genapol PF 80 depends on the composition of the respective building mixtures and the time and intensity of mixing.
Genapol PF 80 can be used in combination with othernonionic, anionic and cationic surfactants. Genapol PF 80 is resistant to water hardness, metal salts and to acids and alkalis in the concentrations normally used. Preliminary tests are required.
Genapol PF 80 has a good wetting and dispersing action coupled with a low foaming tendency.
Genapol PF is used as a low-foaming surfactant with very good dispersing action in detergent and cleaning agent powders. These can be produced simply by mixing the powder components.
Genapol PF 80 is also used as a low-foaming emulsifier in emulsion polymerization and as a dispersing agent for pigment pastes and preparations.
Other applications include reactions in the chemicalindustry.
Genapol PF 80 can be stored for at least to 2 years in original sealed containers at room temperature under the recommended conditions.
Genapol PF 80 undergoes no change whatever in product properties when exposed to cold during transport and storage.
Genapol PF 80 is supplied also in the form of very fine beads. It is an appropriate choice for powder-type detergents and cleaners if surfactants cannot be sprayed on in liquid or paste from. It is easy to blend with other powders, and it has the added advantage of preventing dusting.
It can be used to disperse suspended calcium and magnesium salts, and to remove and disperse soil in acid pickling baths. Because it is nonionic, it can be used for cleaning metal electrolytically.
It can also be employed to solubilise essential oils and to emulsify monomers
