Industry Grade Hydroxyethyl Cellulose

Industry grade Hydroxyethyl Cellulose
Used as thicking agent for painting.

Product Details

As its good water retention,it improves the liquidity and performance of painting. Also Hydroxyethyl Cellulose can improve water retaining ability and adhesive strength when used in wall plasters,render mortars,adhesive plasters and gypsum putty.

Application For Paints

Hydroxyethyl Cellulose is the most commonly used thickener in Latex painting. In addition to thickening the latex paint, HEC has functions of emulsifying, dispersing, stabilizing and water-retaining. It is characterized by the significant thickening effect, excellent color display, film forming and storage range of PH values. Hydroxyethyl Cellulose has good compatibility with other material, such as pigments, auxiliaries, fillers and salts. Paints thickened with Hydroxyethyl Cellulose are of high rheological properties and pseudo-plasticity under various shearing rates, good workability and leveling performance. It could be applied by way of brushing, roller coating or spraying, not easy to drip, sag or spatter.

 

Characteristic

♦ Significant thickening effect

♦ Excellent color display

♦ Film forming and storage range of PH value

♦ Good compatibility with other material (pigments, auxiliaries, fillers and salts)

♦ High rheological properties

♦ Good workability and leveling performance

 

 

Excellent Advantage

♦ High thickening efficiency. Due to there are many different kind of thickening agents, any requirement for thickening efficiency can be reached, especially for aqueous thickening.

♦ Good compatibility. High degree and serialization of compatibility of the modern countless components in the latex paint formulations. Compared to non-cellulosic thickeners, using cellulosic thickeners in the formulation could provide a wider choice.

♦ Good storage stability. Years of experience have shown that the storage stability of latexes thickened with cellulosic thickeners is superior. No matter how is the pH value situation, the latex paint could maintain a uniform viscosity and pigment suspension for a long time.

♦ Anti-sagging. The stresses that occur during the coating process damage the hydration layer established between the thickener and the water. And Once the coating has ended, the latex paint will regain its viscosity and the sag will be prevented.

♦ Stable Viscosity of different PH value. Thickened latex paint with a cellulose-based thickener, the viscosity is stable among a wide PH range (3-11)

♦ Remain Adhesion. Cellulose thickener as a film-forming material, could merge together with latex paint. As long as the choice of latex paint is correct, it could well covered the pigment particles, cellulose-based thickener won’t have any loss of its adhesion.
