What This Grade Is For
Binder Hydroxyethyl Cellulose CAS NO. 9004-62-0 is supplied by Yiyuantong Chemical as a thickener and water-retention aid in water-based adhesives. The listing is written around the identity data buyers check first, so incoming inspection can be matched against the paperwork. Ethyl cellulose (HEC), chemical formula (C2H6O2) n, is a white or light yellow, odorless, non-toxic fibrous or powdered solid prepared by etherification of alkaline cellulose and ethylene oxide (or chloroethanol).
Key Benefits
- Holds water in the adhesive film so open time is long enough to place and adjust the work
- Full identity data on every lot so goods-in can be cleared against the certificate without a query
- Builds body so the paste stays where it is applied on walls and ceilings
- Dissolves in cold water, which suits on-site mixing without heating
- Improves wet tack and bond development on porous substrates
- Held in stock: 800 tonnes of HEC are carried year round, and confirmed orders ship to the named port within 3 working days
Problems It Solves
- Wallpaper and tile paste that dries before the sheet is positioned
- Adhesive that runs off vertical surfaces during application
- Lumpy paste made up on site by hand mixing
Application Scenarios
- Wallpaper and wall covering paste
- Tile adhesive
- Water-based construction adhesive
- Paper and packaging adhesive
Who It Is For
- Adhesive manufacturers
- Dry-mix adhesive blenders
- Private-label paste brands
Technical Features
- Non-ionic backbone, so viscosity survives salt and hard water
- Cold-water soluble, no cooking step needed in the mixing room
- Supplied from 300 to 200000 mPa.s so the grade can be matched to the process
- Molar degree of substitution of 1.8 to 3.0 for biological stability and high transmittance
- Solvent process raises the degree of substitution by 30 to 35 percent against traditional routes

Raw Materials
- High alpha-cellulose refined cotton
- Wood pulp with high cellulose content
- Ethylene oxide
Manufacturing Process
- Alkalisation of refined cotton and wood pulp
- Etherification with ethylene oxide
- Acetone countercurrent washing
- Drying and milling
- 40 mesh screening
- Lot testing and packing
Quality Control
- Every lot is tested in our own laboratory against the customer specification before release
- Third-party verification is available through SGS, which we have worked with on export lots
- Certificate of analysis issued with each shipment; HPLC or NMR data supplied on request
- Acetone countercurrent washing removes process residues before drying and milling
How It Compares
| Methyl cellulose | HEC dissolves cold without the gelling behaviour that methyl cellulose shows on heating |
|---|---|
| Starch paste | Cellulose ether gives a longer open time and resists microbial attack better in storage |
Use Guide
- For dry-blend products, mix the powder with the other dry components before water is added
- For liquid adhesives, sprinkle into water under agitation and hydrate before the resin is added

Binder Hydroxyethyl Cellulose CAS NO. 9004-62-0 FAQ
How long an open time can we expect?
It depends on dose, substrate porosity and temperature. Send the recipe and the conditions on site and we will suggest a grade and dose to trial.
Can it be dry blended?
Yes. Dry blending with the other powders is the normal way to avoid lumping in site-mixed pastes.
What identification data comes with the shipment?
CAS number, EINECS number, chemical formula and the lot analysis. Tell us what your goods-in procedure needs and we will include it.
Are you a manufacturer or a trading company?
We are a manufacturer and you are welcome to visit the plant. Our hydroxyethyl cellulose project runs at 5000 tonnes a year on an acetone countercurrent washing process.
What payment terms do you accept?
L/C, T/T, D/A, D/P, PayPal and Western Union. We have worked with China Export and Credit Insurance Corporation for many years.
How fast can you ship?
Stock items are despatched within 5 days of payment. If the grade is not in stock, production and despatch take 7 to 10 days from payment.
