Our premium Hydroxypropyl Methyl Cellulose (HPMC) is a high-performance, non-ionic cellulose ether designed specifically for the construction chemical industry. Acting as a superior water-retaining agent and thickener, this refined white powder is engineered to optimize the workability and durability of cement-based materials, ensuring a seamless application process and professional-grade results.
Specially formulated for versatility, our HPMC serves as an essential binder in gypsum, putty powder, and various building materials. By significantly prolonging the open time and preventing rapid dehydration, it eliminates shrinkage cracks and enhances the structural strength of the hardened paste, making it the ideal additive for tile adhesives, marble pasting, and reinforcement coatings.

Frequently Asked Questions
HPMC acts as a water-retaining agent and thickener, preventing the mortar from drying too quickly, improving pumpability, and enhancing the overall strength of the finished structure.
By retaining moisture within the mixture, HPMC ensures a slow and uniform drying process, which prevents the shrinkage cracks that typically occur when water evaporates too rapidly.
Yes, it is highly recommended for tile adhesives as it improves the bonding strength, increases the open time for adjustment, and ensures a smooth application on ceramic or marble surfaces.
Yes, our HPMC is refined from high-quality cotton and processed to be a pure white powder, ensuring it does not affect the color of your building materials.
Because HPMC improves the binding efficiency and workability of the mixture, it can often reduce the total amount of cement required to achieve the desired structural strength.
The CAS number for our Hydroxypropyl Methyl Cellulose is 9004-65-3, complying with international chemical standards.
