Application of HPMC in Construction Industry

Hydroxypropyl methylcellulose HPMC occupies an important position in the construction industry. Green and environmentally friendly cellulose will be widely used in the construction industry.


HPMC has an extremely wide range of uses in the building materials industry and is used in large quantities. Cellulose can be used as a retarder, water retention agent, thickener and binder. Cellulose ethers play an important role in common dry-mix mortars, high-efficiency external wall insulation mortars, self-levelling mortars, dry plastering adhesives, tile-bonding dry mortars, high-performance construction putties, crack-resistant internal and external wall putties, waterproof dry-mix mortars, plaster plasters, scraping and whitewashing agents, thin joints and other materials. They have an important influence on the water retention, water requirements, solidity, retardation and workability of mortar systems. Commonly used cellulose ethers in the built-up area include HEC, HPMC, CMC, PAC, MHEC etc.

Why is HPMC widely used in the construction industry?

Water Retention. It can retain water on porous surfaces such as cement boards and bricks on walls.

Film formation. It forms a transparent, tough and soft film with excellent resistance to oil and grease.

Organic solubility. The product is partially soluble in organic solvents such as ethanol/water, propanol/water, dichloroethane and solvent systems consisting of two organic solvents in appropriate proportions.

Thermal gelation. An aqueous solution of the product is heated to form a gel, which reverts to a solution on cooling.

Surface activity. Provides surface activity in solution to achieve the required emulsification and protection of the colloid, as well as phase stabilisation.

Suspension. Hydroxypropylmethylcellulose prevents the precipitation of solid particles and thus inhibits the formation of precipitates.

Binding. Excellent function as a binder for pigments, tobacco products and paper products.

Protection of colloids. Prevents agglomeration or coagulation of droplets and particles.

Non-ionic and inert. The product is a non-ionic cellulose ether and does not combine with metal salts or other ions to form insoluble precipitates.

Water solubility. The product can be dissolved in water in varying portions, the maximum concentration being limited only by the viscosity.

Tasteless and odourless, unaffected by metabolic effects. Used as additives in food and medicine, they are not metabolised in food and do not provide calories.

Acid and base stability. Suitable for use in the pH range 3.0-11.0.
