Application Cases

1. Construction Materials
Putty powder, mortar, and tile adhesive: water retention, thickening, and improved workability
Gypsum products: retardation of setting, enhanced strength, and improved surface quality.
2. Oil Drilling
Drilling fluid filtrate reducers and viscosity enhancers offer clear cost advantages.
3. Papermaking Industry
Surface sizing and wet-end addition to enhance paper strength, smoothness, and printability.
4. Ceramic Industry
Ceramic green-body enhancer and binder, reducing cracking and improving forming yield.
5. Laundry and Daily Chemicals
Detergent anti-redeposition agent to prevent secondary soil adhesion.
6. Food-grade CMS (for select models)
Used as a thickener, stabilizer, and emulsifier, compliant with food additive standards.
