MATECEL® is classified into pure and modified grades. Pure grades are also divided into        HPMC(Hydroxypropyl Methyl Cellulose) and HEMC(Hydroxyethyl Methyl Cellulose).


PMK-150ZS(HPMC, Degree of subsituion K, Viscosity 150000mPa·s, Delayed Solubility)

GMK Grade

GMK grades are finely modified to improve the rheological properties of cellulose ethers        in accordance with various application requirements such as additional thickening, betier        workability, less stickiness, longer open time, etc.

Modified grades are especially produced through chemical reactions, physical blending of        organic or inorganic additives. The viscosity range varies from under 400mPa·s to over        200,000mPa·s.




Usually, non-surface treated MATECEL® can only be dispersed in hot water to prevent        lumping, but surface treated MATECEL® can be dispersed in cold water.

In the meantime, have a look at the brief illustrations below to see the key differences.

Surface treated MATECEL®

Surface treated powder is specially developed to prevent lumping in wet blending        applications such as paints and emulsion based applications. To

make the solution with surface treated powder, powder is directly placed into cold water.        With time, a fully developed-solution with the appropriate

viscosity is prepared through continuous stirring of the solution.

Non-surface treated MATECEL

If non-surface treated powder is put into cold water directly, it easily forms lumps            due to its too quick solubility with cold water. To prevent lumping, put the powder into the            hot water(over 90°C)first, then stir in order to disperse the powder, and then cool down the            solution while stirring continuously.

When non-surface treated powder is used in a dry-mixing application, lumping is not a            concern since each particle of MATECEL® is distributed throughout the final product evenly.

Adjustable Solubility Properties

Our HPMC products have adjustable solubility properties which vary from its degree of            etherification.



Dissolution of MATECEL®

When it comes to water solubility levels and speed, the general dissolution mechanism            of MATECEL® is shown in the graph below.

Dissolution of MATECEL.jpg

Non-surface treated MATECEL®

The viscosity measuring of non-surface treated MATECEL® is impossible in cold water            due to lump formations. The retardation time of surface-treated MATECEL® Approximates to            about 20 minutes at HP 7. However, the higher the PH of the solution is, the shorter the            retardation time will be.

The effect of pH on MATECEL® dissolving times

The viscosity development time is dependent upon the pH of the solution fie surface-            treated grades. The higher the pH of the solutions is, the shorter the retardation time will            be. For paint applications, long-regarded grades are more suitable because of the high pH            conditions (CaCO?,ammonia,etc.) of the applications.

Viscosity comparison through various measurements

Viscosity is a resistance force (based on the flow rate, gravity force, rotation        resistance of the product, etc.). 

In general Hoppler (=Falling B) and Ubelode all types measure Newtonian solutions.

Note that measured values could vary with the types of NDJ viscometer

Relationship between viscosity and molecular weight

The viscosity of a solution is proportional to the weight or chain length of the            MATECEL molecularAverage molecular weight of MATECEL varies from 400 to 200000.

Relationship between viscosity and molecular weight.jpg

Relationship between viscosity and concentration

In general, viscosity is proportional to the concentration of the solution. Limited            to about 2.5% for high viscosity grade.(over 50,000 mPas, 2% solution)

Relationship between viscosity and concentration.jpg

Relationship between viscosity and temperature

The viscosity of MATECEL solution depends on its temperature. As the temperature            increases its viscosity gradually decreases when it reaches a certain temperature, the            viscosity decreases sharply. The trend is shown in the dotted line. That certain temperature            is called Gel-point.

Thickening effect

MATECEL® is used very often as a thickener in building applications as it prevents            segregation and improves the cohesion of the formulation components. 

The viscosity of MATECEL® depends on the degree of polymerization, contraction,            temperature, shear rate, concentration of dissolved salts, and modification. 

In dry mixing production and mortar, the thickening power of pure grades is related            to their solution viscosity. On the other hand, the mortar viscosity of modified grades is            not necessarily proportional to the solution viscosity.

Tile Adhesives

MATECEL® promises the high performance and excellent working efficiencies for attachment            of tiles to various substrates. Being slip resistance and having better open time is the key            to better adhesive requirements.

These improvements can only be gained from MATECEL®.

Effects of raw materials

Slip resistance

Slip resistance is crucial in order to improve working efficiency in applying tile cement        mortars on walls. MATECEL® provides adhesives with better slip property so that tiles can be        applied in a better way. With suitable MATECEL® grades and concentration levels, heavy tiles        over 50 kg can be applied to walls without slipping.

Open time & Tensile adhesion strength

MATECEL® cellulose prolongs the open time during construction,thus giving plenty of time        for correction. Suitable addition rate of MATECEL® ensure longer open time, higher tensile        adhesion strength and better workability.

EIFS with MATECEL® promises even higher        performances and excellent working efficiencies on job sites. MATECEL® leads to high sag resistance and embedding time, which are the required key        properties of EIFS.

2)ETICS(External Thermal Insulation composite Systems)

Better sag resistance

It is well known that mortar sag is a common problem in the filed. Better sag            resistance means that mortar can be applied more efficiently to walls without sagging.

Better sag resistance

Longer time and embedding time

Open time and embedding time refers to the possible working minutes to bond            insulation board or mesh on to fresh mortar is applied on the substrate. This relates to the            skin formation and water evaporation of EIFS mortar. MATECEL® extends the open time and            embedding time of mortars with its high water retention power and controlled skin formation            properties of mortar surfaces.

Longer time and embedding time

Water retention

Water retention is the most significant property of MATECEL®, which controls workable        time.Generally, water retention depends on the viscosity, fineness and dosage of MATECEL®.

Controlling thickening speed

Special type of MATECEL® control the mortar viscosity build-up speed.

In general, the fast thickening effect of MATECEL® are necessary to obtain better sag        resistance and proper rheological functions in machine plasters. On the other hand, slow        thickening enables easy mixing and stable mortar viscosity as well as less lump formation in        manual & finishing plasters.

Workability & Sag resistance

MATECEL® is a vital key to adjust suitable consistency in fresh mortars. Suitable        consistency enables fresh plaster to attach well on walls as well as to make surfaces smooth        and be applied easily without the feeling of stickiness. It can be improve better workability        and a better finished product for your customers.
