What Makes Landu Novastar a Leading Gypsum Retarder Manufacturer?
Landu Novastar is a high-tech manufacturer of gypsum retarders, specializing in protein-based additives that control the setting time of both natural and desulfurized gypsum. With certifications like ISO and REACH, and decades of export experience, Landu delivers consistent quality across global markets. Their products are widely used in gypsum board, plaster, and construction mixtures.
What is Landu Novastar gypsum retarder used for?
Landu Novastar gypsum retarder is used to precisely adjust the setting time of gypsum-based construction materials. This includes:
•Gypsum board production
•Wall putty and skim coat applications
•Gypsum-based plasters and mortars
•Self-leveling flooring systems
By slowing down the hydration reaction of gypsum, Landu’s retarder allows more workable time, reducing waste and improving finish quality.
Whether you’re working with natural gypsum or desulfurized gypsum, this protein-based additive ensures consistent results across various climates and production conditions.

How does Landu control gypsum setting time effectively?
The core of Landu Novastar’s technology lies in its protein-based gypsum retarder formula. This advanced additive works by interfering with the crystallization process of gypsum during hydration, which prolongs the initial setting period.
Unlike synthetic chemicals that may impact strength or bonding, Landu’s formula is optimized to:
•Delay setting without compromising strength
•Improve rheological properties (flow and workability)
•Reduce shrinkage and cracks during drying
The result is smoother, stronger, and more predictable gypsum products — which is essential in large-scale production.
Here’s why Landu Novastar stands out:
1.In-House R&D and Patents: Landu operates a dedicated R&D facility in Shandong Province, constantly improving additive performance.
2.Customized Formulations: They can fine-tune the retarder to match your specific raw material blend and production speed.
3.Consistent Quality Control: Every batch is tested under strict protocols, meeting international and customer-specific standards.
4.Integrated Solutions: They don’t just sell gypsum retarders — they offer cellulose ether, RDP, superplasticizers, and more under the Landercoll and NovaStar brands.
This integrated portfolio makes Landu a one-stop supplier for gypsum additive solutions.
What certifications does Landu Novastar have for gypsum additives?
Global clients need assurance that the additives meet safety and performance standards. Landu Novastar delivers exactly that.
Their products comply with:
•✅ ISO 9001 – Quality management
•✅ REACH Registration – For safe import into the EU
•✅ SGS Testing – Verified purity and performance
•✅ RoHS Compliance – No hazardous substances
Each shipment is accompanied by COA (Certificate of Analysis) and MSDS (Material Safety Data Sheet), ensuring full transparency for international trade.
What are the key applications of protein-based gypsum retarders?
Protein-based gypsum retarders like NovaStar are preferred for their natural compatibility and non-toxic profile. You’ll find them widely used in:
•Drywall production lines
•Industrial prefabricated panels
•3D printed gypsum building elements
•Decorative moldings and architectural plaster
Because they maintain flowability without affecting bonding strength, they’re also great for hand-applied plasters and machine spray applications.
If your product relies on predictable setting time and clean finishing, Landu’s retarder is a solid choice.
