The main applications of hydroxypropyl methylcellulose
As a water-retaining agent and retarder for cement mortar, it enables the mortar to have pumpability. When used as an adhesive in plastering mortar, gypsum materials, putty powder or other building materials, it improves the spreading property and prolongs the operational time. It can be used for bonding tiles, marble, plastic decorations, as a bonding enhancer, and can also reduce the amount of cement. The water-retaining property of HPMC prevents the slurry from cracking due to rapid drying after application, and enhances the strength after hardening.

With excellent water retention properties, it improves pumping and spraying performance, prevents run-off, enhances the molding state, prevents cracking and improves the final surface quality.
06 Water-based coatings – Enhance water retention and prevent stratification
As a plasticizer for latex coatings, it plays a role in improving the operational performance and fluidity of the coatings and putty powders.
Product Advantages of HPMC
Hydroxypropyl Methylcellulose (HPMC) is a high-performance cellulose ether widely used in construction materials and water-based coatings. Its unique properties make it an essential additive for improving product quality and workability. Here are the key advantages of HPMC:
- •Enhanced Adhesion and Durability
HPMC promotes strong bonding between substrates and coatings, thereby increasing adhesion. - •Excellent Compatibility with Various Formulations
Compatible with cement, gypsum, pigments, and fillers, HPMC ensures stable dispersion and uniform texture, vital for consistent product performance. - •Alkali and Temperature Resistance
HPMC maintains stability in alkaline environments and withstands varying temperatures, making it suitable for demanding construction and coating applications. - •Outstanding Water Retention for Construction
HPMC effectively maintains moisture in dry mix mortars, tile adhesives, and plasters, ensuring longer open time and preventing premature drying or cracking during application.
