Description

2-(Trimethoxysilyl)-1,3-Butadiene is a specialized organosilicon compound featuring a reactive butadiene moiety linked to a trimethoxysilyl group. This unique structure makes it a valuable bifunctional monomer and coupling agent, capable of undergoing both silane condensation and diene polymerization or addition reactions. It is primarily utilized in the synthesis of advanced polymeric materials, including specialty silicones, adhesives, and surface-modifying agents. Industries such as advanced composites, electronics, and specialty coatings rely on this chemical for developing materials with tailored properties.

Application

• Crosslinking Agent for Silicone Polymers: Used to introduce reactive diene functionality into silicone networks, enhancing crosslink density and thermal stability.
• Surface Modification of Fillers: Acts as a coupling agent for inorganic fillers (e.g., silica, glass) in composite materials, improving dispersion and interfacial adhesion with organic polymer matrices.
• Synthesis of Functionalized Polymers: Serves as a monomer for creating polymers with pendant silyl groups, useful in adhesion promotion and as precursors for further chemical modification.
• Adhesive and Sealant Formulations: Incorporated to improve the bonding strength, flexibility, and environmental resistance of silicone-based adhesives and sealants.
• Electronic Encapsulants: Used in the formulation of protective coatings and encapsulants for electronic components due to its potential to enhance material properties.
• Research & Development: A key intermediate in organic and polymer chemistry research for developing novel hybrid organic-inorganic materials.

Quality Control

Our production of 2-(Trimethoxysilyl)-1,3-Butadiene adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to verify identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specified parameters. Our quality system is designed to meet the exacting standards required for R&D and industrial-scale manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, and open flame.
