Description:

Mud and gypsum are a substrate used to cover and protect the walls and ceilings of buildings, and both contain cement, sand and lime gypsum and high-performance additives.

Mud is applied to the exterior walls of buildings. It provides a protective layer against weathering and improves the appearance of the building.

Gypsum is applied to the interior walls and ceilings of buildings. It provides a smooth and even surface and improves the acoustic and fire performance of the building.

High-performance additives include our cellulose ethers (HPMC, MHEC) and redispersible emulsion powders (RDP/VAE).

(HPMC, HEMC, RDP) in mud and gypsum role:

1. Improve workability: It can improve constructability and improve construction quality by providing better adhesion and reducing sagging.

2. Improve stability: cellulose ether has good thickening, which is conducive to good adhesion to the wall, and makes its surface smooth, easy to construct, and no viscous feeling.

3. Improve pumpability: cellulose ether has good thickening and water retention, which is conducive to the good flow of materials in the pipeline. It reduces clogging during machine spraying.

4. Increased water retention: Cellulose ethers have good water retention, which helps prevent cracking and ensures better curing.

5. Enhance durability: RDP adequate hydration reaction and good adhesion make the material stronger.

6. Better adhesion: Good water retention of cellulose ether helps cement to fully hydrate, and RDP has strong viscosity. They are all designed to strengthen the adhesion of cement.

HPMC, MHEC and RDP are among the largest application areas for mud and gypsum, and we have developed products of different grades and properties to meet all customer needs. We can also offer custom formulations that can provide you with the most suitable raw materials and products for your specific local requirements.
