The lubrication effect provided by HONGHAI® HPMC can greatly reduce the friction between the gypsum particles, thereby making mixing effortless and shortens the mixing time. Ease of mixing also reduces the clumping that usually occurs.
Increases water demand
Compared to unmodified gypsum, HONGHAI® HPMC modified building materials can drastically increase the water demand, which increases both working time and volumetric yield, thus making the formulation much more economic.
Improves water retention
HONGHAI® HPMC modified Gypsum building materials can prevent leakage of water into the sub-surface, thus prolongs hydration time and increases the open and correction time.
Better temperature stability
Hot weather usually prevents successful plaster application, due to the fast evaporation rate and difficulty to properly cure a placed project. HONGHAI® HPMC can make hot weather applications possible, by reducing the evaporation rate through its water retention and film formation properties, thereby giving the workers time to finish and cure the project properly.
Increases Final Strength
Due to the myriad of properties which are imparted by the HONGHAI® HPMC addition, the final strength is improved.
