【Application】



1. Cement based plaster


(1) Improve uniformity, make plaster easier to smear, improve sag resistance, enhance fluidity and pumpability, and improve work efficiency.
(2) High water retention, prolonging the placement time of the mortar, improving work efficiency, and facilitating the high mechanical strength of the mortar hydration and solidification.
(3) Control the introduction of air to eliminate cracks on the surface of the coating to form the desired smooth surface.


2. Gypsum-based plaster and gypsum products


(1) Improve uniformity, make plaster easier to smear, improve sag resistance, enhance fluidity and pumpability, and improve work efficiency.
(2) High water retention, prolonging the placement time of the mortar, improving work efficiency, and facilitating the high mechanical strength of the mortar hydration and solidification.
(3) Control the uniformity of the consistency of the mortar to form the desired surface coating.


3. Masonry mortar
(1) Enhance the adhesion to the masonry surface, enhance water retention, and increase the strength of the mortar.
(2) Improve lubricity and plasticity, improve workability; use mortar improved by cellulose ether, which is easier to construct, saves construction time and reduces construction costs.
(3) Extra high water retention cellulose ether for high water absorption bricks.


4. Joint filler


(1) Excellent water retention, extended open time and improved work efficiency. Highly lubricious and easier to mix.

(2) Improve the shrinkage resistance and crack resistance and improve the surface quality of the coating.

(3) Improve the adhesion of the bonding surface to provide a smooth, smooth texture.


5. Tile Adhesive


(1) It is easy to dry mix ingredients, no clumps, improve application speed, improve construction performance, save working time and reduce work cost.
(2) Improve the efficiency of tiling by extending the opening time and provide excellent adhesion.


6. Self-leveling floor material


(1) Provides viscosity and acts as an anti-settling aid. (2) Enhance the pumpability of fluidity and improve the efficiency of paving the ground. (3) Control water retention and shrinkage, reducing cracking and shrinkage on the ground.


7. Ready-mixed mortar
HPMC products for ready-mixed mortar are better than ordinary products in the ready-mixed mortar, ensuring that the inorganic cementing material is fully hydrated, significantly preventing the bond strength from being caused by excessive drying, and Crack caused by drying shrinkage. HPMC also has a certain venting effect. The HPMC product for premixed mortar has a proper amount of venting, uniformity and small bubbles, which can improve the strength and smearing of the ready-mixed mortar. The HPMC product specially used for ready-mixed mortar has a certain retarding effect, which can extend the opening time of the ready-mixed mortar and reduce the construction difficulty.
