Methylhydroxyethylcellulose (MHEC)

Methylhydroxyethylcellulose (MHEC) product series are nonionic cellulose ethers that are easily soluble in cold water, insoluble in hot water, have good compatibility with electrolytes (such as inorganic salts), and are stable over a wide pH range. VitaPlus products can be widely used in cementitious bonding materials, tile adhesives, wall putty, and plaster. They can also be used in combination with other building material additives, such as starch ethers,surfactants, thickeners and other polymer materials, to provide users with high-quality, environmentally friendly and efficient building materials.

Excellent water-retention

VitaPlus MHEC has superb water retention properties. Adding MHEC to the mortar can lock in water, improve the open time and wettability of the mortar, and prevent the mortar from losing water too quickly, which can cause cracking. It is especially suitable for use in hot weather.

Excellent workability

VitaPlus MHEC helps wall putty products to have excellent workability and ease of application, reducing the difficulty of application and avoiding cracking. The desired surface effect and mechanical properties are ultimately obtained.

Excellent thickening

VitaPlus MHEC has an extremely thickening effect, thickening mortar and plaster products in a short time, giving the mortar good anti-slip properties and excellent workability.

FAQ

Can't find the answer?

What is “cellulose ether”?

A kind of nonionic water-soluble specialty polymer derived from cellulose.
Physical form: powder that, when dissolved into water (or a water-based system), gives a clear, thick solution
Thickener, rheological agent
Water retention agent
Binder and stabilizer
Suspending agent

Production of cellulose ether

Cellulose ethers for construction are non-ionic water-soluble polymers made of:

Cellulose (wood pulp or cotton wool);
Halogenated hydrocarbons (chloromethane, ethyl chloride or other long-chain halides);
Epoxy compounds (ethylene oxide, propylene oxide, etc).

The characteristics of MHEC and HPMC

MHEC

Higher gelling temperature
High water-retention, even at high ambient temperature
Good wetting ability
Good wetting ability

HPMC

Wide application range
Good thickening effect
Air void stability, suitable for waterproof mortar
Easy to obtain smooth surface
A little hydrophobicity

Application characteristics of different viscosities

High viscosity grades :

Cost effective (lower addition rate to achieve the same consistency)
More shear thining
Skin formation

Low viscosity grades :

High quality feel (the final product remains creamy under shear)
Longer open time (better water retention)
Higher addition rate
More body, less slip
