Description

Silane, Methoxy- CAS NO 2171-96-2 is a highly reactive organosilicon compound, specifically a methoxysilane, that serves as a versatile building block and surface modification agent. Its core value lies in its ability to introduce methoxysilyl groups, enabling adhesion promotion, crosslinking, and hydrophobicity in various materials. This chemical is essential for manufacturers and R&D teams in the coatings, adhesives, and advanced materials sectors seeking to enhance product performance and durability.

Application

• Adhesion Promoter: A key component in primers and coupling agents for improving the bond between inorganic materials (glass, metals, minerals) and organic polymers (paints, sealants, composites).
• Surface Modification: Used to functionalize silica, glass fibers, and other fillers to improve dispersion and compatibility within polymer matrices like silicones, epoxies, and polyurethanes.
• Crosslinking Agent: Employed in moisture-curing silicone formulations and room-temperature vulcanizing (RTV) systems to form stable siloxane networks.
• Hydrophobic Coatings: Acts as a precursor for creating water-repellent surfaces on construction materials, textiles, and electronic components.
• Chemical Synthesis Intermediate: Serves as a starting material or reagent in organic and organometallic synthesis for pharmaceuticals and specialty chemicals.
• Nanomaterial Functionalization: Used to modify nanoparticles (e.g., silica, titania) to tailor their surface properties for specific advanced material applications.

Quality Control

Our Silane, Methoxy- is produced under stringent quality management protocols. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing specific batch results are provided and available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
