Foam formation during gypsum processing is a persistent challenge that directly compromises product integrity. Gypsum defoamers are essential additives engineered to address this issue, delivering measurable improvements in final product strength, surface finish, and manufacturing efficiency. With dedicated R&D expertise, Yuanlian Chemical has formulated a range of high-performance defoaming solutions tailored to the specific demands of the gypsum industry, serving as a trusted partner for plaster manufacturers across Europe.

The Impact of Foam in Gypsum Manufacturing

The introduction of air during mixing, pouring, and pumping operations inevitably leads to foam. This results in significant production drawbacks:

• Visible surface defects such as pinholes and blemishes.

• Compromised mechanical strength and long-term durability of the cured gypsum.

• Incomplete mold filling, leading to higher product rejection rates.

• Reduced line efficiency and increased overall production costs.

Key Advantages of Yuanlian Chemical Gypsum Defoamers

Our technically advanced defoamer series is designed to deliver reliable performance with distinct benefits:

1. Fast-Acting & Long-Lasting: Our modified polysiloxane-based formulations provide rapid foam collapse and sustained foam suppression throughout the entire processing window.

2. Broad Compatibility & Stability: Excellent compatibility with standard gypsum additives (e.g., retarders, plasticizers) without interfering with set times or final properties. Stable performance in hard water conditions.

3. Application-Specific Formulations: We offer tailored solutions for various gypsum types, including alpha high-strength plaster, beta building plaster, and specialty molding plasters.

4. Safe & Sustainable: Our products are developed in compliance with European standards, ensuring safety for personnel and no negative impact on the end product's performance or environmental profile.

Critical Application Benefits Across Key Sectors

• Gypsum Boards & Blocks: Ensures homogeneous slurry distribution, eliminating internal voids to enhance the load-bearing capacity and surface quality of panels and blocks.

• Gypsum Plasters & Finishes: Improves workability and final surface aesthetics for decorative applications, minimizing imperfections for a smoother finish.

• Precision Moulds & Castings: Guarantees flawless reproduction of intricate details, critical for high-value art pieces and technical molds.

• Self-Levelling Flooring Compounds: Essential for achieving optimal flow characteristics and a perfectly smooth, defect-free surface.

Recommended Application for Optimal Results

• Point of Addition: For best results, introduce during the initial water and powder mixing phase.

• Typical Dosage: Generally between 0.05% and 0.3% of gypsum weight. We advise conducting trials to determine the optimal dosage for your specific formulation.

• Dilution (if required): Certain products can be pre-diluted with water (1:5 to 1:10 ratio) for easier incorporation.

• Mixing: Ensure complete and uniform dispersion within the slurry for consistent performance.
