Chemical Structure of MECELLOSE

What is MECELLOSE ?MECELLOSE is our brand name that stands for Hydroxy ethyl methyl cellulose(HEMC), Hydroxy

propyl methyl cellulose(HPMC) and Methyl cellulose(MC) products, which are water-soluble cel-

lulose ethers. These ethers are formed by substituting some of the cellulose hydroxyl groups

with methoxyl and hydroxyl propoxyl or hydroxyl ethoxyl groups. MECELLOSE is applied to build-

ing materials, paints, personal care, pharmaceuticals, and also used in civil construction.

GENERAL PROPERTY OF MECELLOSE


GENERAL PROPERTY OF MECELLOSE

General PropertiesWater Solubility | MECELLOSE easily dissolves in cold water.

Water Retention | MECELLOSE has the property to reduce water-

loss of its formulations when its formulations are applied to water

absorbing surfaces such as a wallboard, etc.

Non-ionic Charge | MECELLOSE is compatible with other addi-

tives in aqueous solutions and provides a stable combination of

water solubility

pH Stability | MECELLOSE is stable in the range of pH

3.0~11.0. However, the solubility of MECELLOSE is affected by

an acid or alkali.

Organic Solubility | MECELLOSE is soluble in some binary organ-

ic and organic-water solvent systems due to hydrophobic groups in

its molecule.

Suspending Aids | MECELLOSE enhances the stability of suspen-

sion throughout the solution.

Surface Activity | MECELLOSE has a surfactant property in the solu-

tion where protective colloid function and emulsification are required.

Thermal Gelation | MECELLOSE's aqueous solution gels when

the temperature of its solution rises up to a specific level. The gel

returns to its original solution state upon cooling.

Thickening & Binding | MECELLOSE provides a thickening proper-

ty of its solution and improves the adhesion degree of formulations.

Film Formation | MECELLOSE forms clear, tough, flexible films

which have an excellent barrier property to oils and grease.

Lubrication | MECELLOSE improves workability, and processing

of cement based products and ceramic extrusions through its lubri-

cant property.

Emulsification | MECELLOSE stabilizes emulsions in its solution.

Enzyme Resistance | MECELLOSE provides excellent viscosity

stability during long-term storage due to resistance against fungi

and bacteria attacks.

HOW TO PREPARE SOLUTION OF MECELLOSE

HOW TO PREPARE SOLUTION OF MECELLOSE

MECELLOSE dissolves in waterMECELLOSE dissolves in cold water by subsequent hydration but disperses in hot water. Highly etherified MECELLOSE (PMA, PMB and PMH

grades) is also soluble in some organic solvent mixtures due to its hydrophobic property. We have different types of MECELLOSE whichinfluence the process in making solutions.

If the non-surface treated powder is put into cold water directly, it easily forms lump due to its quick

solubility in cold water.

To prevent lumping, put the powder into hot water(over 90℃) first, stir to disperse and then cool down

the solution with stirring.

When non-surface treated powder is used in a dry-mixing application, lumping is not of concern

because each particle of MECELLOSE is distributed throughout the final product.

Surface treated powder is specially developed to prevent lumping in the wet blending application

such as paints and emulsion based ones. To make the solution with surface treated powder, place

the powder directly into cold water. With time the viscosity fully developed-solution is prepared

with continuous stirring.

Each modified MECELLOSE shows different solubility properties. The solubility of modified MECEL-

LOSE depends on the original property of the basic MECELLOSE and its degree of modification.

SOLUTION PROPERTIES OF MECELLOSE


Viscosity comparison by various measurements- Viscosity is a resistance force(flow rate, gravity force, rotation resistance, etc)

- In General, Ubelode, Hoppler(=Falling Ball) type measure Newtonian solution.

Relationship between viscosity and molecular weight- MECELLOSE molecular weight (or chain length) is proportional to the viscosity.

- Average molecular weight of MECELLOSE is from 20,000 to 200,000.

Dissolution of MECELLOSE- The general dissolution mechanism of MECELLOSE is shown in the graph that follow.

- Because of fast solubility of non-surface treated grade, dispersing time is short.

Stirring time

The impact of pH upon MECELLOSE solution time- The surface treated grade is dependent upon the pH of the solution.

- For paint application, the long retarded grade is suitable because of high pH condition(CaCO3, ammonia, etc)

Non-surface treated and surface treated MECELLOSENon-surface treated MECELLOSE : the viscosity-measuring of non-surface treated MECELLOSE is

impossible in cold water because of lump formation.

Surface treated MECELLOSE : Retardation time of surface treated MECELLOSE is about 20minutes at

pH7. However, the higher the pH of the solution is, the shorter retardation time will be.

Solubility in organic solvents- MECELLOSE is soluble in water, some organic solvents, or water-organic co-solvents.

- PMA type is the best solube one in organic solvents.

- PMB and PMH type are applicable to paint remover.

→ PMA, PMB and PMH are soluble in Methanol/(some organic solvents, IPA,

PACKAGING & STORAGE


PACKAGING & STORAGE

PackagingMECELLOSE is packed in the following two types of package:

A. 20 Kg | net multi-layer paper bag with polyethylene inner liner

- 600 Kg is placed on one pallet, and 9.6 MT is loaded in one Container of 20 ft.

B. 350 Kg | net jumbo bag with polyethylene inner liner

- 1,050 Kg is placed on one pallet, and 10.5 MT is loaded in one Container of 20 ft.

StorageMECELLOSE should be stored under dry and clean conditions in

its original packaging due to its hygroscopic property. If not,

MECELLOSE can absorb moisture relative to the humidity in the

air. Mecellose is not a perishable product. If MECELLOSE is

stored in closed containers, in its original packaging and in a dry

place at room temperature, MECELLOSE can maintain its original

properties.

Safety informationWhile MECELLOSE is classified as a non-hazardous material, be

aware of the following notice to avoid unexpected accidents

when handling:

Storage | Dust of Mecellose is capable of exploding. To avoid

dust explosion, store it away from heat, spark, and fire, and do

not expose it directly to high temperatures(over 150 °C). General

precaution outlined in NFPA 63, "Prevention of dust explosions

in industrial plants" and NFPA 654 are recommended. Keep

Mecellose away from any kinds of organic chemicals.

Handling | Solutions of Meccellose are very slippery. To avoid

any accidents, sweep the spilled powder and keep dry.

Health | The toxicological properties of this material have not

been investigated. Use appropriate procedures to avoid direct

contact such the skin or eyes and to prevent inhalation.

- Eyes : immediately flush eyes with plenty of water for at least 15 minutes,

occasionally lifting the upper and lower eyelids.

- Skin : Flush skin with plenty of soap and water for at least 15 minutes while

removing contaminated clothing and shoes.

- Ingestion : Do not induce vomiting. Allow the victim to rinse his mouth and

then to drink 2-4 cup of water, and seek medical advice.

- Inhalation : Remove from exposure to fresh air immediately.
