HEC Technical Data Sheet


HEC Technical Data Sheet


Hydroxy Ethyl Cellulose (HEC) is a nonionic surfactant and odorless, free flowing white powder. It is  characterized by hygroscopicity and can be dissolved in both cold and hot water. It has high thickening  effect, excellent rheological properties, suspension, adhesion, emulsification, filming, watering and  protective colloid properties.

Typical Physical Properties 

Appearance: White to slightly off-white fibrous or granular powder 

Moisture, %: 5.0 max 

PH level (1% solution in distilled water): 6.0 - 8.5 

D.S: 1.8 - 3.0 

Particle Size: Min 90% pass through 80 mesh 

Viscosity, mPa.s: 300 – 150,000


● Paints & Coats Can be polymerized with vinyl acetate emulsion to improve stability of polymerizing system within  wide range of PH value. In the finished product manufacturing, HEC used as a role of dispersion,  stabilization and thickening in paint, especially high-PVA coating, providing excellent coating  properties. 

● Construction & Building Materials Used as thickening agent and adhesive for cement and dry mixed mortars. As its good water retention,  it improves the liquidity and performance of mortars and extends open time. HEC also can improve  water retaining ability and adhesive strength when used in wall plasters, render mortars, adhesive  plasters and gypsum putty.

● Oil Drilling Used as thickening agent to make mud achieve good mobility and stability, easy for mud pump which is required by drilling, well set, cementing and fracturing operations. 

● Personal Care Guarantee the stability of paste and improve the taste as its strong salt and acid resistance. Besides,  water retaining ability and emulsifying capacity make toothpaste difficulty to dry. 

● Water Based Ink Help ink dry and fast penetrate. Moreover, it’s also widely used textile printing and dyeing, paper  making, daily chemicals and so on. 

● High Molecular Polymer Used as dispersant for suspension polymer such as styrene, acrylate, acrylonitrile etc.  

Recommended Handling All personnel handling this material must handle it as an industrial chemical, wearing protective  equipment and observing the precautions as described in the Material Safety Data Sheet (MSDS). 

Packaging and Storage 

Packed in 25 kgs composite film bags. Store in dry, well-ventilated area. Keep container closed. Keep away from heat, sparks and flames.  Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding,  shrink- wrapping and /or stacking.
