Description

Natrosol hydroxyethylcellulose (HEC) grades are offered in different viscosity levels (molecular weights), and particle size distributions. Natrosol HEC grades for paints and coatings applications are typically glyoxylated (R-treated) for ease of incorporation. In latex architectural paints, Natrosol HEC is known for superior color performance, stability, shear-thinning, application properties and sag resistance.

Natrosol FPS fluidized polymer suspensions are solvent-free liquid versions of Natrosol hydroxyethylcellulose (HEC). Virtually all viscosity grades of Natrosol commonly used in paint and coatings and Natrosol Plus, are also available in a fluidized (FPS) version. HEC polymer is pre-dispersed in a stabilized aqueous media, creating an easy-to-handle, pourable, pumpable liquid cellulosic thickener.

Natrosol FPS can be easily added to the grind, but is most advantageous when added directly to the let-down stage of paint making, where it readily disperses and incorporates quickly without lumping. FPS is also commonly used as a post-thickener to adjust the final viscosity of finished batches.

  • Free-flowing white powder
  • Pseudoplastic or shear-thinning
  • Easily dissolved in cold or hot water to give clear solutions of varying viscosities
  • Low to medium molecular weight types are fully soluble in glycerol
  • Good solubility in hydro- alcoholic systems containing up to 60 percent ethanol
