HPMC For Drymix Mortar

Dry mix mortar additives are essential components that are used to enhance the performance of dry mix mortar products. As a professional manufacturer of fine chemical cellulose ether, we offer a range of drymix mortar additives include HPMC and VAE/RDP powder. HPMC is a water-soluble polymer that is derived from cellulose, a natural polymer found in plants. It is an odorless, non-toxic, and non-ionic additive that is used to improve the workability, adhesion, and durability of dry mix mortars.


Hydroxypropyl methyl cellulose HPMC
COMMON NAME HYDROXYPROPYL METHYL CELLULOSE
ABBREVIATION HPMC
CAS NO. 9004-65-3
STANDARDS COMPLIANT ENTERPRISE STANDARD
CHEMICAL FORMULA R=CH2CH(CH3)OH


PROPERTIES OF HPMC for Drymix Mortar:

* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.

* Charring temperature: 280-300℃.

* Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )

* Real specific gravity: 1.26-1.31.

* Browning temperature: 190-200℃.

* Surface tension: (2% water solution) 42-56dyn.cm.

* Properties: Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60RT Hydroxypropyl Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.


Construction grade Hydroxyporpyl Methyl Cellulose(HPMC)

Construction grade HPMC is widely used in drymix mortar products, including tile adhesives, plastering mortar, grouts, and self-leveling compounds. Could be soluble in water and form the transparent solution. As the important mortar additives, Hydroxyproypl methyl Cellulose could increase the water retention, increase the workability and increase open time etc.


HPMC for Drymix Mortar Application Guide
EIFS adhesive mortar

• Bond strength: Choose the right mortar mix additives HPMC could provide the greatest bond strength of mortar

• Good workability: Adhesive mortar HPMC have good consistency, non-sagging property could make the work easier during using of distribution method.

• Water retention: HPMC have good water retention, make sure all other additives can also reach the best performance.


EIFS surface mortar

• Bigger scrape area: The good film property and the suitable viscosity, choose right grade HPMC make the wet mortar more smooth and easy to scrape on the surface, same weight of wet mortar can cover bigger area.

• Anti-cracking: Choose the right specification of HPMC, The excellent property can make sure all other additives in mortar could reach the best performance, reduce the crack on surface.

• Stability: Surface mortar HPMC have good stability in hot environment, keep good water retention even in high temperature.
