High-Content Organosilicone Defoamer LY-XP201 for Versatile Industrial Applications

LY-XP201 is a new type of high-content, high-efficiency organosilicone defoamer precisely formulated from premium imported raw materials. Developed as a universal, alkali-resistant antifoam agent, it exhibits exceptional emulsion stability and outstanding water dispersibility.

Engineered to solve severe foaming issues in challenging chemical environments, LY-XP201 delivers rapid knockdown (defoaming) along with long-lasting control (anti-foaming) across various anionic, water-based systems. Due to its high concentration and optimized molecular design, its active dosage requirement is significantly lower than standard commercial defoamers, providing modern processing lines with a cost-effective, high-stability foam control solution.

Core Technical Advantages & Value Proposition

1. High Speed Defoaming & Long-Lasting Anti-Foaming Performance

LY-XP201 provides dual-action efficiency. Upon addition, it rapidly spreads across liquid-gas interfaces to break down existing surface macro-foam at high speeds. Simultaneously, the stabilized silicone matrix suppresses micro-foam generation over extended operational cycles, ensuring process continuity.

2. Exceptional Alkali Resistance & Emulsion Stability

Traditional silicone emulsions frequently suffer from chemical breakdown, oil separation, or spots when exposed to alkaline media or high shear. LY-XP201 features a robust nonionic emulsification system that maintains high structural integrity under alkali conditions, preventing chemical plating or residue defects on substrates.

3. Excellent Dispersion in Anionic Water-Based Systems

The nonionic nature of LY-XP201 ensures superb compatibility, preventing precipitation or interactions when added to highly filled anionic water systems. It disperses easily and uniformly in cold water without forming agglomerates, preserving the chemical balance of your process stream.

4. Lower Dosage for Maximized Cost Efficiency

Thanks to its advanced high-content formulation, the required volume of LY-XP201 per processing batch is lower than that of conventional defoamers. This reduction in chemical additive consumption optimizes raw material costs while keeping system contaminants to a minimum.

Wide Industrial Applications

LY-XP201 is highly versatile and effective across a broad spectrum of water-phase processing industries:

• Paper & Pulp Manufacturing: Extensively used as a papermaking additive and in pulp washing/screening lines to eliminate structural foam and improve drainage speeds.
• Chemical Processing & Synthesis: Controls complex foaming during agitation, blending, and chemical transport.
• Industrial Cleaning & Texturing: Ideal for high-pressure industrial cleaning lines, textile dyeing, and finishing loops.
• Environmental & Infrastructure Engineering: Manages foam in municipal/industrial sewage treatment plants and cement cementing slurries.
• Bio-Fermentation: Suppresses foam generation in aeration tanks and biological fermentation vessels.

Application & Dosage Guidelines

To capture the highest defoaming response, please strictly implement the following steps:

• Dosage Rate: Actual consumption depends heavily on the specific application parameters; however, it is technically recommended to ensure the final concentration of the organosilicone active substance within the foaming solution is not less than 10 ppm.
• Pre-Handling: Shake or stir the container gently before product dispensing to guarantee absolute uniformity of the emulsion polymer layers.
• Addition Method: The product can be metered directly into the system at a point of high turbulence. Alternatively, it can be pre-diluted with 1 to 10 times its volume in cold water for uniform continuous feeding.

Packaging, Storage & Regulatory Safety

• Logistics Packaging: Supplied in 25 kg or 50 kg plastic drums, or 200 kg plastic-lined iron drums. Custom packaging options are available upon customer request.
• Storage Environment: Store in a cool, dry indoor location away from direct sunlight and explosion-prone heat sources. Keep containers tightly closed when not in use.
• Shelf Life & Transportation: Fulfills standard safety criteria as a non-toxic, non-flammable, and non-explosive chemical substance, permitting standard chemical transport logistics. Holds a guaranteed shelf life of 6 months under proper sealed storage conditions.
