Physicochemical Properties
a) Appearance: White to pale yellow color in the state of fibrous or powdery solid. Non-toxic and odorless.
b) Solubility: HEC is soluble in water and insoluble in the normal organic solvents.
c) PH Stability: Within the range of 2-12, the viscosity changes little. PH value out of this range, the viscosity decreases.
d) Property performance: HEC has the property performance of thickening, suspension, adhesive, emulsion, dispersion, water retention and protective colloid. And can be used for the solution preparation of different viscosity.
e) Activity: Being stable at normal temperature and pressure.
-Avoid high temperature, moisture and heat.
-With very good salt solubility for the dielectric, and its aqueous solution allows containing high concentrations of salts and has stable performance.
Latex paint
It can provide pseudoplastic and wide compatibility, and wide range of color paint, latex, surface active agent, emulsifying agent, defoaming agent and antiseptic matching use..
Good show color:it has good compatibility with other components
Rheological modifier: with pseudoplastic or increase the viscosity of the coating
Viscosity stability: good viscosity stability
Water retention: good water retention performance and opening time
Building (filled seam an agent)
It is to optimize tape joint compound formula of the product performance and development. It has the effect of the contact in field application.
