Emcell 1209

Hydroxy Ethyl Cellulose (HEC) 
 
Emcell 1209 (HEC), which is used to support water-holding and as a rheology modifier in water-based paints, is a water-soluble polymer with a high degree of viscosity. It is in a class that has biostability in solution against enzymatic attack.

Emcell 1209 is widely used for water-based paints. Colored pigments provide good pseudoplastic fluidity and wide compatibility with emulsion polymers, surfactants, emulsifiers, defoamers and preservatives. To avoid lump formations that may occur faster than optimal dissolution rate, Emcell 1209 is properly processed to achieve optimum hydration time for application.

Viscosity (1% Solution, 25 oC)                                                                                     3.500 ~ 5.000 CPS
PH Value                                                                                                                         6.0 ~ 8.5

Note: Viscosity was measured in Brookfield viscometer with 1% solution, 20 ºС

Packaging
Emcell 1209 is packaged in 25 Kg net weight paper sacks with a surface made of polyethylene inside. They are loaded on pallets, with a net of 1000 Kg şn 40 sacks. Depending on the şnstallation, pallets can also be loaded with 1250 – 1500 Kg. Empty paper sacks can be recycled.

Storage and Shelf Life
Unopened sacks can be stored for several years. Emcell 1209 can last for a long time provided it is kept at room temperature and dry in closed containers or original package. For products with high viscosity, a decrease in viscosity can be observed for products stored for a long time (more than 1 year). Once the package is opened, it must be closed off again and tightly tied.
