Brief Introduction:

1.Modcell® C3051 cellulose ether is a kind of non-ionic, water soluble polymer powder which is developed to improve rheological performance of latex paints, it can be as rheology modifiers in latex paints. It is a kind of modified Hydroxyethyl cellulose, the appearance is tasteless, odorless and non-toxic white to slight yellow granular powder.

2.It is mainly used in Multi-colors paints, paints for interior & exterior wall, stone paints, texture paints and limestone render.

3.It is nonionic cellulose ether. HEC has functions of thickening, building, emulsifying, dispersing, stabilizing and water-maintaining. It is easily dissolved in cold and hot water to provide a wide range of solution viscosity, form film and offer protective colloid effect.

4.HEC is thickener of high concentration electrolyte. Its water-retaining capacity is twice as MC. It has a good flow regulation.

5.HEC is the most commonly used thickener in Latex paint. In addition thickening to the Latex paint, it has the function of emulsifying, dispersing, stabilizing and water-retaining. Its properties are significant effect of thickening, and good show color, film forming and storage stability. HEC is nonionic cellulose ether which can be used in a wide range of pH. It has good compatibility with other material, such as pigment, auxiliaries, fillers and salts, good workability and leveling. It not easy to dripping sagging and spattering.

Storage and package:

Modcell® C3051 Cellulose ether belongs to hygroscopic and hydrophilic polymer powder, so it should be stored and delivered under dry and clean conditions in its original package form and away from heat.

After the package is opened for production, tight re-sealing must be taken to avoid ingress of moisture.

Shelf life and Product safety

At least 2 years under cool and dry condition. For material storage over shelf life, quality confirmation test should be done before use.

According to EU legislation on dangerous substances and preparations, Modcell® cellulose ether does not belong to hazardous material. Further information on safety aspects is given in Material Safety Data Sheet.
