Description

Silicic Acid (H4Sio4), Disodium Salt, Reaction Products With Chlorotrimethylsilane And 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluoro-1-Decanol CAS NO 125476-71-3 is a specialized organosilicon compound engineered to deliver unique surface-modifying properties. This product is critical for applications requiring the combination of inorganic silica-like stability with the exceptional oil and water repellency of long-chain perfluoroalkyl groups. It is primarily sought by formulators in the coatings, textiles, and advanced material sectors for developing high-performance, durable surface treatments.

Application

• Fluorinated Surface Modifier for Coatings: Imparts outstanding water, oil, and stain repellency to architectural, automotive, and industrial coatings.
• Textile Finishing Agent: Used to create durable, breathable, and highly hydrophobic/oleophobic finishes for technical and outdoor fabrics.
• Paper and Packaging Treatment: Enhances grease resistance and provides barrier properties in food-contact and specialty paper products.
• Additive for Polymers and Composites: Improves surface slip, mold release, and environmental resistance when incorporated into plastics and composite materials.
• Stone and Masonry Protector: Serves as a key component in formulations designed to protect building materials from water ingress, staining, and weathering.
• Specialty Surfactant/Emulsifier: Acts as a fluorosurfactant in demanding applications requiring stability in harsh chemical environments.

Quality Control

Our production of this specialty fluorosilane adheres to a strict quality management system. Each batch is characterized to ensure consistent performance in surface energy modification and chemical composition. While this is a custom-engineered product, we provide comprehensive batch-specific Certificates of Analysis (COA) detailing key parameters such as fluorine content, solids percentage, viscosity, and solvent composition to guarantee it meets your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and maintain product integrity.
