Description

5-Hexenyltriethoxysilane,95% CAS NO 52034-14-7 is a high-purity organosilicon compound featuring a terminal alkene group and hydrolyzable ethoxy silane functionality. This dual reactivity makes it a versatile coupling agent and surface modifier, enabling strong covalent bonds between inorganic substrates and organic polymers. It is primarily used by formulators and manufacturers in the adhesives, sealants, coatings, and composite materials industries to enhance interfacial adhesion, mechanical properties, and durability.

Application

• Adhesive & Sealant Formulation: As a crosslinking agent and adhesion promoter, particularly for silicone-modified polymers and hybrid systems.
• Surface Treatment for Fillers & Reinforcements: For modifying glass fibers, minerals (e.g., silica, clay), and other inorganic fillers to improve compatibility and dispersion in organic polymer matrices.
• Coatings & Inks: To enhance the adhesion of coatings to difficult substrates like metals, glass, and plastics, and to improve scratch and chemical resistance.
• Composite Materials: As a key coupling agent in fiber-reinforced plastics (FRP) and mineral-filled composites to boost mechanical strength and moisture resistance.
• Rubber & Elastomer Modification: To functionalize silica used in tire tread compounds and high-performance elastomers, reducing rolling resistance and improving wear.
• Hybrid Organic-Inorganic Materials (ORMOSILs): As a precursor in sol-gel processes for creating advanced materials with tailored optical, mechanical, or surface properties.

Quality Control

Our 5-Hexenyltriethoxysilane is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC), to verify identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, ensuring full traceability and compliance with your material specifications and quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep containers tightly sealed when not in use to prevent degradation by atmospheric moisture. Keep away from heat, sparks, and open flame.
