Product Description
HEC300P is a nonionic,water-soluble polymer from wood pulps or cotton linters that can be used of water retention aid and rheology modifier in water-based paints.HEC300P 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
HEC300P is widely used for 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,HEC300P is properly treated to achieve optimum hydration time for the application.

Storage&Packaging
HEC300P is packed 25kgnet multi-layer paper bag with polyethylene inner liner.HEC300P should be stored under dry and clean conditions in its original packaging due to its hygroscopic property.If not,HEC300 can absorb moisture relative to the humidity in the air.HEC300P is not a perishable product.
If it stored in closed containers,in its original packaging and in a dry place at room temperature,HEC300P can maintain its original properties.
