2. Good compatibility with most inorganic salts and a wide range of gum and resin.

products have excellent stability, to ensure a nice shelf life for paint.

6. Small viscosity fluctuation.

Anti- biodegradation performance

HEC hydration time counts from the initial wetting to a moment when the solution starts to become viscous. Hydration time could be varied to meet a special requirement. HEC hydration time, apparently affected by the pH value.Typically ranges from 4 to 25 minutes.

The solution properties lll

is that it acts as a thickener, in creasing the viscosity of the liquid,and its thickening depends on its concentration (shown below). In addition, the effect of different viscosity grade on the thickening property can alsobe clearly seen, under the other constant parameters, the viscosity of HEC thickener increases with the increase of viscosity grade.
