Application
Hydroxypropyl Methyl Cellulose Ether(HPMC) is mainly used in the dry building materials from the construction industry, including the water-resistant putty powder, putty paste, steel putty, paint glue, thermal insulation mortar and so on. It has a good water retention effect, and it is easy to be constructed with a good luminosity, besides, the viscosity and gel time can be customized according to the requirement of customers.
Tile Adhesive
Good water retention: prolonged opening time will make tiling more efficient. Improved adhesion and sliding resistance: especially for heavy tiles. Better workability: lubricity and plasticity of plaster is ensured, mortar can be applied easier and quicker.
Cement Plaster / Dry mix mortar
Easy dry mix formula due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles. Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time. Increased water demand: increased open time, expanded spry area and more economical formulation. Easier spreading and improved sagging resistance due to improved consistency.
Wall putty
Water retention: maximized water content in slurry. Anti-sagging: when spreading a thicker coat corrugation can be avoided. Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation ,HPMC can increase the mortar volume.
Exterior Insulation and Finish System ( EIFS )
Improved adhesion. Good wetting ability for EPS board and substrate. Reduced air entrancement and water uptake.
Self-leveling Mortar
Protection from water exudation and material sedimentation. No effect on slurry fluidity with low viscosity HPMC, while its water retention characteristics improve the finish performance on the surface.
Crack Filler
Better workability: proper thickness and plasticity. Water retention ensures prolonged work time. Sag resistance: improved mortar bonding ability.

FAQ
What is HPMC used for?
Hydroxypropyl methylcellulose (HPMC) is a cellulose ether in which the hydroxyl groups on the cellulose chain are replaced by methoxy or hydroxypropyl groups. HPMC is used as a thickener, adhesive and film former in agrochemicals, coatings, ceramics, adhesives, inks and a variety of other applications. The aqueous solution of HPMC undergoes reversible gelation when heated, thereby controllably increasing the green strength of the green ceramic body.
Is HPMC safe for humans?
HPMC is the abbreviation of hydroxypropyl methylcellulose. It is a dissolving agent commonly used in pharmaceutical, food, construction and cosmetics fields. Overall, HPMC is generally considered safe and is widely used in many applications.
However, safety depends on use, dosage and individual differences. In the pharmaceutical and food industries, products using HPMC are often subject to necessary safety assessment and supervision. If you have safety concerns about HPMC for a specific use or product, it is best to consult the relevant scientific literature or consult a professional.
What are the disadvantages of HPMC?
HPMC, as a polymer, has shown good properties in many applications, but it also has some shortcomings. HPMC is a soluble dye in cold water and requires a certain temperature to fully dissolve. Thermal stability of HPMC may be relatively low compared to other materials. In high temperature environments, it may cascade or lose some performance. The strength of HPMC may decrease in dry environments, which may impact some applications requiring moisturizing strength.
