what is Cellulose Ether ? what is the Applications of Cellulose
Ether in Building Materials?
Cellulose ether is a type of water-soluble polymer derived from
natural cellulose, which is a primary structural component of
plant cell walls. Cellulose ethers are commonly used in building
materials as additives to modify the properties of cement-based
materials such as mortar, grout, and concrete.
The main applications of cellulose ether in building materials
are:
Water retention: Cellulose ether can improve the water
retention capacity of building materials, which can enhance
workability and prevent the material from drying out too quickly.
Thickening: Cellulose ether can thicken building materials,
improving their consistency and preventing them from sagging
or dripping.
Workability: Cellulose ether can improve the workability of
building materials, making them easier to apply and spread.
Set time control: Cellulose ether can control the setting time of
building materials, allowing for better control of the hardening
process.
Adhesion: Cellulose ether can improve the adhesion of building
materials to substrates, increasing the bond strength.
Durability: Cellulose ether can improve the durability of building
materials by enhancing their resistance to water, freeze-thaw
cycles, and chemical exposure.
Rheology modification: Cellulose ether can modify the rheology
of building materials, improving their flow properties and
preventing segregation.
In summary, cellulose ether is a versatile additive in building
materials that can provide several benefits such as water
retention, thickening, workability, set time control, adhesion,
durability, and rheology modification.
HPMC stands for Hydroxypropyl Methylcellulose, which is a
non-ionic cellulose ether. In mortar, HPMC is primarily used as a
thickener, water retention agent, and workability enhancer.
HPMC can help to improve the performance of mortar by
providing the following functions:
Water retention: HPMC can hold water in the mortar, which
can help to prevent the mortar from drying out too quickly,
leading to a better bond and stronger final product.
Improved workability: HPMC can improve the workability of
mortar by reducing the need for excessive mixing and allowing
for better spreadability and leveling.
Increased adhesion: HPMC can help to improve the adhesion
of the mortar to the building material by enhancing the bond
strength.
Reduced shrinkage: HPMC can help to reduce the shrinkage
of the mortar during the curing process, which can help to
prevent cracks from forming.
Improved sag resistance: HPMC can help to improve the sag
resistance of the mortar, which is particularly important in
vertical applications, such as wall rendering.
In summary, HPMC can provide several benefits to mortar,
including improved workability, adhesion, water retention,
reduced shrinkage, and improved sag resistance.

Cellulose
Hydroxypropyl Methyl Cellulose (HPMC)
HPMC is non-ionic cellulose ether made from natural cotton
fiber under series of chemical processing. It’s odorless,
tasteless and non-toxic white powder, can be dissolved in
normal water to form a transparent viscous solution with the
properties of thickening,binding, dispersing, emulsifying, film
coating, suspending, absorbing, gelling, water retention and
colloid protection.
HPMC can be used in water or used for organic solvent coating,
featuring excellent viscosity and film forming. It has better
property, increasing compressive strength and avoiding lupm.
It's widely used in Wall putty,skim coat,tile
adhesive,mortars,gypsum plaster,blocks joingting,daily
chemicals,etc.
Hydroxypropyl methylcellulose, also known as hypromellose,
cellulose ethers, is made by using highly pure cotton cellulose
as a raw material and by special etherification under alkaline
conditions.
Products name:Hydroxy Propyl Methyl Cellulose
Appearance:White powder
Application:Adhesive Mortars,Skim Coat,Wall Putty,Tile
Adhesive,Tile Bond,Tile Grout,Gypsum Plaster,Cement
Plaster,Blocks Jointing etc.

Hydroxypropyl methyl cellulose (HPMC) is a nonionic cellulose
ether prepared by a series of chemical processing using natural
polymer material cellulose as a raw material. they are an
odorless, non-toxic white powder that swells in cold water into
a clear or slightly turbid colloidal solution.
It has the characteristics of
thickening,bonding,dispersing,emulsifying,
filmforming,suspension,adsorption,gelation,
surface activity, moisture retention and protective colloid.
Feature:
1. Water-soluble, non-ionic cellulose ether
