Gypsum Based Products
Gypsum-based products are integral to modern construction, offering versatile, sustainable, and high-performance solutions for interior finishes and structural elements. As a leading provider of specialized chemical additives, Keiway Chemical draws on advanced formulation expertise to enhance gypsum systems. Our Hydroxypropyl Methylcellulose (HPMC), Redispersible Polymer Powder (RDP), Gypsum Retarder, Polycarboxylate Ether (PCE), and Defoamer are engineered to optimize key properties such as workability, durability, flowability, and surface quality, ensuring compliance with international standards like EN 13963 and ASTM C475 while minimizing environmental impact through reduced water demand and energy-efficient processing.
Main Gypsum Applications
- Gypsum Plaster: Used for smooth wall and ceiling finishes in residential and commercial buildings, providing excellent fire resistance and acoustic performance.
- Gypsum Board (Drywall or Plasterboard): Essential for partition walls, ceilings, and fire-rated assemblies, valued for its lightweight design and rapid installation.
- Gypsum-Based Joint Compounds: Employed to fill, tape, and smooth joints between gypsum boards, ensuring seamless surfaces ready for painting or decoration.
- Gypsum Putty: Applied for fine surface leveling and repair, delivering a high-quality, crack-resistant finish in preparation for coatings.
- Gypsum-Based Self-Leveling Compounds: Ideal for creating flat, durable floor underlayments, supporting heavy loads and compatible with various floor coverings.
In gypsum-based applications such as gypsum plaster, gypsum board, gypsum joint compounds, and gypsum putty, Keiway Chemical additives including HPMC, RDP, and gypsum retarders are widely used to optimize workability, setting control, adhesion, and overall performance. For gypsum self-leveling compounds, in addition to HPMC, RDP, and gypsum retarders, high-performance PCE superplasticizers and defoamers are also applied to enhance fluidity, ensure stable dispersion, control air content, and achieve smooth, defect-free leveling surfaces.
