What are Gypsum-based Products?
Gypsum-based products are construction materials formulated primarily with gypsum, processed through calcination, grinding, and additive blending. They are widely used in interior decoration and building applications thanks to their lightweight nature, fire resistance, sound insulation, and easy workability.
Typical gypsum product types include:
- Gypsum Blocks — lightweight blocks for non-load-bearing interior walls
- Gypsum Board — interior partitions and ceilings for homes, offices, and commercial spaces
- Gypsum Putty — surface leveling and smoothing before painting or wallpapering
- Gypsum Mortar — wall plastering, floor leveling, and tile-related applications in dry areas
Common Challenges in Gypsum-based Products
Manufacturers of gypsum boards, putty, and mortars often face issues such as:
- Moisture sensitivity — gypsum can absorb water and soften in humid environments
- Low mechanical robustness — brittle structure may lead to cracking and handling damage
- Fast setting — short workable time can complicate production lines or on-site application
- Workability instability — difficult spreading, poor consistency, or rapid drying affecting finish quality
- Surface defects — pinholes, bubbles, hollowing, or uneven surface appearance after curing
- Efflorescence risk — surface salt crystallization that impacts appearance and indicates moisture transport
High-Performance Additives for Gypsum-based Products
BOTAI provides a practical additive portfolio for gypsum board, gypsum putty, and gypsum mortars—helping improve workability, water resistance, surface quality, and early strength development. Each product below follows the standard module format for quick evaluation.

With suitable grade selection and formulation trials, these additives can help you achieve:
Improved workability & finish — smoother spreading, better consistency, and more stable workable time
Better strength & toughness — improved resistance to cracking and handling damage during transport and application (system dependent)
Reduced moisture sensitivity — lower water uptake and improved performance in humidity-prone indoor environments (system dependent)
Cleaner surface appearance — fewer bubbles/pinholes and improved film/matrix integrity for better aesthetics
Improved production efficiency — faster early strength development supporting quicker demolding and handling (system dependent)
More stable long-term durability — improved service stability depending on gypsum type, formulation, and curing conditions
Note: Results depend on gypsum type, binder/additive system, water ratio, mixing energy, ambient humidity/temperature, and process controls. Lab and pilot trials are recommended before scale-up.

FAQ
In many gypsum systems, our additives can be formulated together with commonly used retarders, plasticizers, and fillers. Share your current formulation framework and we can recommend a compatibility screening plan.
Yes. We can provide samples for lab screening and pilot trials. Sample type and quantity depend on product form (powder vs liquid) and your test plan.
Yes. We can provide available product documentation (such as TDS/SDS) and support your evaluation based on the target market and any required standard.
Lead time depends on grade, order size, and shipping mode. Powders are commonly supplied in 25 kg bags; liquid products (if applicable) can be supplied in drums/IBC subject to availability. Share your destination for an updated schedule.
Yes. We support grade selection, trial planning, and troubleshooting for workability, surface quality, strength development, and moisture resistance during evaluation and scale-up.
