KimaCell® HEC HS100000 Hydroxyethyl cellulose is non-ionic soluble Cellulose ethers have been widely used in paints& coatings. Adding HEC to latex paint, it can make the latex paint have good workability and easy to paint; the spatter of paint can be reduced when brushing and rolling; high water retention can help the leveling performance of construction, so as to avoid brush marks and can be used Ensure the uniformity of film formation; overcome the flocculation of pigments and ensure the best use of pigments; good thickening effect can save dosage and reduce costs; good storage stability can save preservatives; strong hiding power and scrub resistance; And it has good thixotropy in various shear force ranges.

KimaCell® HEC HS100000 Hydroxyethyl cellulose ether products are often used as a thickener for latex paint preferred. The addition of HEC with appropriate specification and viscosity in latex paint can improve the construction performance of latex paint, prevent splashing, improve storage stability and hiding power.
The function of HEC as bellow :
Flow properties and construction properties
Latex paints produced with HEC HS100000 in many ways, especially in lightweight formulations with fixed pack volumes. The latex paint produced by HEC has good rheology at various shear rates, can be applied by brush or roller, has good workability, and can form a coating film with high wettability on a dry substrate.
Adding HEC, the latex paint exhibits pseudoplastic thixotropy under the action of shear force. When the shear rate increases, the viscosity decreases and remains for a short time when the shear rate decreases.
Thickening
The latex paint thickened by HEC HS100000 can not only save the cost of raw materials, but also increase the water resistance and scrub resistance of the latex paint with the reduction of the amount of thickener.
