Effect of at-home bleaching with different thickeners and aging on

Natrosol (hydroxyethylcellulose) is a cellulose-based polymer largely used in various materials such as latex emulsions, water-soluble resins, surfactants and detergents, anti-foaming agents, plastifying agents, and organic solvents as they have excellent compatibility with different types of composites.Alternative thickeners to an industrial thickener (natrosol) in the production of emulsion paints were investigated.

Each specific grade of Natrosol HEC is designated by a product type, beginning with 250, which indicates an average molar substitution of 2.5 (5 ethylene oxide groups per 2 anhydroglucose units, as illustrated in Figure 1). This is followed by an indication of viscosity/molecular weight type and other designators.Thickener performance, especially for synthetic associative thickeners, depends on interactions with latexes and surface-active paint ingredients such as surfactants and dispersants. However, each of the four classes of organic thickeners is characterized by several attributes that are fairly independent of paint type and A Practical Guide to Thickener Selection PCI Magazine

Natrosol® Hydroxyethylcellulose Physical and Chemical Properties

Because viscosity is an exponential function of concentration and degree of polymerization, the viscosity resulting from blending is not an arithmetic mean. VISCOSITY A blending chart (VC-440), which is available from Aqualon, can be used to determine the result of blending various amounts of two viscosity types of Natrosol.Natrosol™ 250 HHR. Natrosol™ 250 HHR by Ashland is a high efficiency non-ionic thickener, water retention aid and rheology modifier. It is a water-soluble, hydroxyethyl cellulose surface-treated with glyoxal.
