Hydroxypropyl Methylcellulose (HPMC)
Hydroxypropyl methylcellulose (HPMC) is a non-ionic, water soluble cellulose ether with properties of film forming, water retention, stability and adhesiveness. It is frequently used in building materials to enhance adhesion, water retention, lubricity, shrink resistance and crack resistance.
Modified cellulose ethers can help enhance sag resistance, crack resistance, pressure resistance and tensile strength. Modified cellulose ether is therefore the ideal option for plaster and cement based mortars. It is non-toxic, tasteless white or off-white powder that dissolves easily in hot or cold water.
HPMC can also be used in ceramics, tobaccos and detergents, etc.

HPMC can serve as thickening agent, dispersant agent, emulsifying agent or film-forming agent, and its industrialized products are applicable to the production of daily chemicals, synthetic resin, construction and coating materials.
Suitable for use in the recipe of following construction materials- Waterproof putty powder
- Cement sand mortar
- Cement-based brick/tile, and bonding between tile and base brick
- Plaster for gypsum board base
- Cement-based structural plaster
25kg per bag (multi-layer paper bag with polyethylene interlayer)
HPMC can be stored for 12 months in sealed bags under dry and cool circumstance. The opened bags should be sealed as soon as possible to avoid moisture.
