Hydroxyethyl Cellulose(HEC)
CAS NO.:9004-62-0
Hydroxyethyl Cellulose
(HEC) is nonionic soluble cellulose ethers, both soluble in hot and cold water. Hydroxyethyl Cellulose is a white free-flowing granular powder, treated from the alkali cellulose and ethylene oxide by etherification, Hydroxyethyl Cellulose has been widely used in paint and coating, oil drilling ,pharma, food, textile, paper-making, PVC and other application fields. It has good thickening, suspending, dispersing, emulsifying, film-forming, water-protecting and providing protective colloid properties.

3.Hydroxyethyl Cellulose (HEC) Applications:
In water based paint,it plays a role of dispersing and protecting gels,enhancing reaction stability of agglomerate system,ensuring homogeneous distribution of pigment and stuffing, and providing effect of thickening, improving fluidity.
In oil drilling,it is used as stabilizer and thickening agent, lubricating agent for well drilling,completing and consolidating to give slurry a good fluidity and stability.
In construction,HEC can be used as thickening agent and cohesive agent to improve the fluidity and workability,increase initial gelling strength and avoid cracking.
In brushing and cohering plaster,it may obviously raise water-holding and coherence strength.
In daily-use chemical such as toothpaste it gives a good physical and chemical property,making it good in shape,long period of storage, hard be dry and permeated.
In cosmetic field,it can increase material density, adding lubrication and smoothness.
Besides,it has wide application in ink, textile dyeing & printing,paper making, pharmaceuticals, food, agriculture etc.
4.Hydroxyethyl Cellulose (HEC) Using method :
First Method: Directly Put In
1. Pour pure water into bucket provided with stirrer.
2. At beginning slowly stir,evenly scatter HEC into solution.
3. Stir until all the HEC granules fully wetted.
4. First put in anti-mildew agent,then add in additives such as pigment,disperser etc.
5. Carry on stirring until all the HEC and additives entirely dissolved(viscosity in the solution obviously increasing),then put in other ingredients to react.
Second Method: Prepare Mother Liquor for Use
First prepare thick mother liquor,then put it in product.The advantage of the method is flexibility,the liquor may be directly be put in product.The procedure and way to use is same as 1-4 in the method(Ⅰ),be sure stir until fully dissolved into sticky and thick solution and put anti-mildew agent into mother liquor as early as possible.
Packaging: 25kg paper bags inner with PE bags.
