Description

Triethoxysilylbutyraldehyde: 90% is a high-purity organosilicon compound featuring a reactive aldehyde group and hydrolyzable ethoxysilane functionality. This dual reactivity makes it a valuable bifunctional coupling agent and intermediate for creating hybrid organic-inorganic materials. It is primarily needed by manufacturers in the silicone polymers, specialty coatings, and adhesives industries, where it is used to enhance surface adhesion, crosslinking, and material compatibility.

Application

• Silane Coupling Agent: Used to improve the adhesion of polymers (e.g., silicones, epoxies) to inorganic substrates like glass, metals, and minerals.
• Surface Modification: Functionalizes silica, nanoparticles, and other fillers to enhance dispersion and compatibility within polymer matrices.
• Crosslinking Agent: Serves as a co-monomer or crosslinker in the synthesis of moisture-curable silicone resins and sealants.
• Intermediate for Specialty Chemicals: The reactive aldehyde group allows for further chemical transformations, making it a key building block for custom silanes and functional polymers.
• Adhesive & Sealant Formulations: Incorporated to boost the bonding strength and environmental resistance of industrial adhesives and sealants.
• Hybrid Material Synthesis: Used in sol-gel processes to create advanced hybrid coatings with tailored properties like hardness, scratch resistance, and hydrophobicity.

Quality Control

Our Triethoxysilylbutyraldehyde: 90% undergoes rigorous quality testing to ensure compliance with industry standards. Each batch is controlled against stringent specifications for purity, identity, and key impurities. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) and minimize exposure to air and moisture to maintain product integrity.
