Description

n-(3-Triethoxysilylpropyl)-4-Hydroxybutyramide is a specialized organofunctional silane coupling agent that bridges organic polymers and inorganic substrates. This compound matters for its unique bifunctional structure, enabling superior adhesion, moisture resistance, and mechanical property enhancement in composite materials. Industries such as adhesives, sealants, coatings, and advanced composites need this chemical to solve critical bonding challenges and improve product longevity.

Application

• Adhesive & Sealant Formulations: Acts as a key adhesion promoter between organic resins (e.g., epoxies, polyurethanes) and glass, metal, or mineral surfaces, significantly improving bond strength and durability.
• Fiber-Reinforced Composites: Used as a sizing or coupling agent for glass, carbon, or aramid fibers to enhance the interfacial adhesion and stress transfer between the fiber and the polymer matrix.
• Surface Modification & Primers: Applied to inorganic substrates (metals, glass, fillers) to create a reactive organic interface, improving the wettability and compatibility for subsequent coating or bonding processes.
• Crosslinking Agent: Functions in silicone-based systems where the triethoxysilyl group can undergo hydrolysis and condensation to form siloxane networks, while the amide/hydroxy groups offer organic compatibility.
• Mineral-Filled Plastics & Elastomers: Enhances the dispersion and interfacial bonding of fillers (e.g., silica, clay) in rubber and plastic compounds, leading to improved mechanical properties and reduced viscosity.
• Waterborne & Solventborne Coatings: Improves the adhesion of coatings to difficult substrates, providing enhanced corrosion resistance and long-term performance in protective and decorative coatings.

Quality Control

Our production of n-(3-Triethoxysilylpropyl)-4-Hydroxybutyramide adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay (HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure consistency and high purity. Certificates of Analysis (COA) documenting all critical parameters are provided and 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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and degradation upon contact with atmospheric moisture.
