Description

Triethoxsilylbutyraldehyde, Tech-90 is a versatile organosilicon compound that serves as a key bifunctional building block, featuring both a reactive aldehyde group and hydrolyzable ethoxysilane groups. This dual functionality makes it an essential precursor for creating advanced hybrid organic-inorganic materials with tailored surface properties. It is particularly valuable for industries requiring precise surface modification, adhesion promotion, and the development of specialty polymers and coatings.

Application

• Surface Modification Agent: Used to functionalize inorganic surfaces like glass, silica, and metals, imparting specific chemical properties for improved compatibility or reactivity.
• Adhesion Promoter: Enhances the bond between organic polymers (e.g., paints, sealants, adhesives) and inorganic substrates in composite materials.
• Crosslinking Agent: Employed in the synthesis of silicone-based resins, elastomers, and coatings to introduce aldehyde functionality for further chemical reactions.
• Intermediate for Specialty Chemicals: Serves as a key starting material for synthesizing more complex silane coupling agents and functionalized siloxanes.
• Hydrophobic Coatings: A component in formulations for creating water-repellent surfaces on textiles, construction materials, and electronics.
• Analytical & Research Chemistry: Used in laboratories for immobilizing biomolecules or creating specialized chromatographic stationary phases.

Quality Control

Our Triethoxsilylbutyraldehyde, Tech-90 is manufactured under a rigorous quality management system. Every batch is analyzed to ensure it meets the defined technical specifications, with a typical purity of ≥90%. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles 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 area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture.
