HEC50000P
Product Description
HEC50000P is a nonionic ,water-soluble polymer from wood pulps or cotton linters that can be used as water retention aid and rheology modifier in water-based paints. HEC50000P is a high viscosity grade of hydroxy ethyl cellulose. It is available in a grade that has bio-stability in solution against enzymatic attacks.
Application
HEC50000P is widely used as water-based paints. It provides good pseudoplastic flow and wide compatibility with colored pigments, emulsion polymers, surfactants, emulsifiers, defoamers, and preservatives. In order to avoid lump formations caused by a quicker than optimal dissolution rate, HEC50000P is properly treated to achieve optimum hydration time for the application.
Typical properties
Physical Data | Specification | Remark |
Appearance | Off White Powder | |
Particle Size | 90%<425μm | Vibrator Sieve |
Moisture Content | Max.5% | |

PH | 6.0~8.5 |
Storage & Packaging
HEC50000P is packed 25kg net multi-layer paper bag with polyethylene inner liner. HEC50000P should be stored under dry and clean conditions in its original packaging due to its hygroscopic property. If not, HEC50000P can absorb moisture relative to the humidity in the air. HEC50000P is not a perishable product.
If it is stored in closed containers, in its original packaging and in a dry place at room temperature,HEC50000P can maintain its original properties.

HEC hydration time counts from the initial wetting to a moment when the solution starts to become viscous. Hydrationtime could be varied to meet a special requirement.HEC hydration time,apparently affected by the pH value, typicallyranges from 4 to 25 minutes.
