Product Description

Product Details
----------------------------------------------
Hydroxyethyl cellulose (HEC)
Hydroxyethyl cellulose is developed and produced by our company for many years. Hydroxyethyl cellulose is a kind of uniform and efficient non-ionic water-soluble polymer. Two products hpy30000s and hpy50000s with different viscosity range are introduced, which are suitable for different fields. Hpy30000s and hpy50000s are mainly used for emulsion paint and hpy50000s for stone paint.

Main quality performance
Versatility: it can be used in different emulsion systems and pH conditions.
Excellent color paste and pigment compatibility
Good water retention
Good color mixing viscosity stability
Good storage stability
Better low foaming and transparency

Features and uses
Hydroxyethyl cellulose (HEC) is a kind of nonionic cellulose ether, which is made from natural polymer cellulose by a series of chemical processes. It is a kind of odorless, tasteless and nontoxic white powder or particle, which can be dissolved in cold water to form a transparent viscous solution, and the dissolution is not affected by pH value. It has the characteristics of thickening, adhesion, dispersion, emulsification, film-forming, suspension, adsorption, surface activity, water retention and salt resistance.
Connect hydroxyethyl cellulose can be widely used in water-based coating, construction mortar, oil drilling, synthetic resin, ceramic industry, medicine, food, textile, agriculture, cosmetics, tobacco, ink, paper daily chemistry and other fields.

Physical and chemical properties:
1, This product is white or yellowish odorless, odorless, tasteless and easy to flow powder, which can be dissolved in cold water and hot water. Generally speaking, the insoluble pH value in most organic solvents changes less in the range of 2-12, but the viscosity decreases beyond this range. The HEC after surface treatment disperses in cold water and does not agglomerate. The dissolution rate is relatively fast. It generally takes about 15min to slowly increase the viscosity.
2. 100 mesh screening rate ≥ 99%; softening temperature: 135-140 ºC; surface density: 0.35-0.61g/ml; decomposition temperature: 205-210 ºC; slow combustion rate; equilibrium moisture content: 23 ºC, 6% at 50% RH, 9% at 84% RH. (RH is relative humidity).

Dissolution method:
Dissolved in water:
Slowly add HEC into the water with violent agitation until it is completely dissolved. If all materials are added, it will be difficult to dissolve;
