Gypsum Plaster

Gypsum Plaster

Gypsum plaster, also known as Plaster of Paris (POP), is a quick-setting material derived from gypsum (calcium sulfate dihydrate). It is widely used for interior wall plaster, ceiling finishes, and decorative moldings.

Gypsum plaster has gained immense popularity in modern construction due to its smooth finish, fast application, and eco-friendly properties. Unlike traditional cement plaster, gypsum wall plaster offers superior durability, fire resistance, and moisture resistance, making it an ideal choice for interior wall finishing.

With the growing demand for gypsum-based construction materials, architects, builders, and homeowners are increasingly shifting toward this efficient alternative. This comprehensive guide covers gypsum plaster, its benefits, applications, and a detailed comparison with cement plaster.

Reliable performance for high-quality applications

Dongyuan Shengda Cellulose ether and RDP are important additives in gypsum plaster. Cellulose ether mainly improves water retention, workability, and surface smoothness by preventing rapid moisture loss during application.

RDP mainly enhances adhesion strength, flexibility, and crack resistance, helping improve the durability and stability of gypsum plaster.

Innovative Additives for Tile Adhesive

Hydroxypropyl Methyl Cellulose

Hydroxypropyl Methyl Cellulose (HPMC) is a water-soluble, non-toxic polymer additive. It is widely used in various industries due to its properties as a thickener, binder, film-former, emulsifier, and water retention agent, ensuring improved stability, efficiency, and performance across diverse industrial and commercial applications.

Hydroxyethyl Methyl Cellulose

MHEC (Methyl Hydroxyethyl Cellulose) powder is a non-ionic cellulose ether derived from natural polymer cellulose, acting as a thickener, binder, and high-performance water retention agent. It is widely used in construction materials (tile adhesives, dry-mix mortars, wall putty) to improve workability and durability.

Redispersible Polymer Powder

Redispersible polymer powder is a free-flowing white or light yellow powder made from vinyl acetate–ethylene polymer emulsion through high-temperature, high-pressure spray drying. When it comes into contact with water, it can form a stable polymer emulsion whose properties are the same as those of the original emulsion.
