Description

Butanediamide, N,n-Dihexadecyl-N'-[3-(Triethoxysilyl)Propyl]- is a specialized organosilane derivative that functions as a high-performance coupling agent and surface modifier. Its molecular structure is engineered to create durable covalent bonds between inorganic substrates and organic polymers, significantly enhancing composite material properties. This compound is essential for manufacturers in the advanced materials, coatings, and polymer industries seeking to improve adhesion, dispersion, and mechanical strength in their formulations.

Application

• Polymer Composite Reinforcement: Acts as a key coupling agent in glass fiber, mineral-filled, and silica-reinforced composites (e.g., nylon, polypropylene, polyethylene) to improve interfacial adhesion and mechanical properties.
• Surface Treatment for Fillers: Used to modify the surface of inorganic fillers like silica, clay, and calcium carbonate to enhance compatibility and dispersion within polymer matrices.
• Adhesion Promoter in Coatings & Sealants: Improves the bond strength and durability of coatings, adhesives, and sealants to challenging substrates such as metals, glass, and minerals.
• Rubber Compounding: Enhances the reinforcement of silica in "green tire" formulations, reducing rolling resistance and improving wet grip.
• Nanomaterial Functionalization: Employed to graft organic functionalities onto nanoparticles (e.g., silica, alumina) for specialized applications in electronics and advanced ceramics.
• Water Repellent & Protective Coatings: Used to create hydrophobic surfaces on construction materials, textiles, and stone.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and hydrolysis of the triethoxysilyl groups. Keep away from strong acids and bases.
