Plaster Additives/Render Additives is made of semi-hydrated gypsum as the base material, high molecular polymer as the gelling material, and dry-mixed with inorganic fillers. It has the advantages of convenient construction, less loss, good hollowing and cracking control, energy saving and environmental protection, thin plastering construction, and reducing the cost of later rectification.

We can recommend suitable product models and tailor-made precise formulas for you according to your use environment, raw materials and other needs, and provide you with technical support during production and use.

In Plasters/Renders, the role of additives:

1. HPMC (Hydroxypropyl Methylcellulose): As a water retainer and thickener, HPMC can improve the construction performance of mortar, prevent water from evaporating too quickly, and enhance adhesion and anti-slip properties.

2. HEMC (Hydroxyethyl Methylcellulose): Similar to HPMC, HEMC is also a water retainer and thickener that can improve the fluidity and construction performance of mortar, while improving crack resistance and durability.

3. RDP (Redispersible Polymer Powder): As a polymer modifier, RDP can significantly improve the bonding strength, flexibility and impact resistance of mortar, while improving water resistance and durability.

4. PVA (Polyvinyl Alcohol): As a binder and film former, PVA can enhance the adhesion and cohesion of mortar, improve construction performance and surface smoothness.

5. HPS (High Performance Water Reducer): As a water reducer, HPS can reduce the water consumption of mortar, increase density and strength, and improve fluidity and construction performance.

6. Gypsum Retarder: Used to adjust the setting time of gypsum-based mortar, prevent too fast hardening, and ensure sufficient construction time and operating performance.
