Description

Ethenyl Silanetriol Triacetate, Acetoxy-Methoxy Exchange Products With Trimethoxy[3-(Oxiranylmethoxy)Propyl]Silane CAS NO 154518-41-9 is a specialized organosilicon compound that functions as a reactive silane coupling agent and crosslinker. This product is engineered to provide superior adhesion promotion and enhanced compatibility between organic polymers and inorganic substrates. It is essential for manufacturers in the adhesives, sealants, coatings, and composite materials industries seeking to improve product performance and durability.

Application

• Adhesive & Sealant Formulations: Acts as a crosslinking agent and adhesion promoter in silicone-based and hybrid polymer systems, enhancing bond strength to glass, metals, and minerals.
• Surface Modification & Primers: Used to treat inorganic surfaces (e.g., glass fibers, minerals, metals) to improve the interfacial adhesion with organic resins in composite materials.
• Coatings & Inks: Incorporated into specialty coatings to improve scratch resistance, chemical resistance, and adhesion to difficult substrates.
• Reinforced Plastics & Composites: Serves as a coupling agent in fiberglass-reinforced plastics (FRP) and mineral-filled composites to enhance mechanical properties and moisture resistance.
• Moisture-Curing Systems: Utilized in one-component, room-temperature vulcanizing (RTV) sealants and encapsulants where it crosslinks upon exposure to atmospheric moisture.
• Epoxy Resin Modification: The oxirane (epoxy) functionality allows for co-reaction with epoxy resins, modifying flexibility, toughness, and adhesion characteristics.

Quality Control

Our production of this silane coupling agent adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed to confirm critical parameters such as functional group content, viscosity, and purity. Certificates of Analysis (COA) documenting these specifications 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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent premature hydrolysis and maintain shelf life.
