Description

1,5-Divinylhexamethyltrisiloxane is a specialized organosilicon compound featuring reactive vinyl groups on a short-chain siloxane backbone. This structure matters for its dual functionality, serving as a versatile crosslinking agent and a reactive intermediate in silicone polymer synthesis. It is primarily needed by manufacturers in the silicone elastomer, adhesive, and specialty coating industries seeking to enhance material properties through controlled curing and network formation.

Application

• Crosslinking Agent for Silicone Elastomers: Used in the production of high-performance Liquid Silicone Rubber (LSR) and High-Consistency Rubber (HCR) to impart superior mechanical strength and thermal stability.
• Reactive Intermediate for Functional Silicones: Serves as a key building block in the synthesis of vinyl-terminated or vinyl-functional polysiloxanes and silicone resins.
• Adhesive and Sealant Formulations: Enhances the cure characteristics and adhesion properties of addition-cure silicone adhesives and sealants.
• Release Coatings and Paper Liners: A critical component in platinum-catalyzed addition cure systems for creating durable, non-stick release surfaces.
• Modifier for Organic Polymers: Utilized to introduce siloxane segments into organic polymer chains, improving flexibility, weatherability, and surface characteristics.
• Research & Development: Employed in academic and industrial R&D for developing novel hybrid organic-inorganic materials and advanced silicone copolymers.

Quality Control

Our 1,5-Divinylhexamethyltrisiloxane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and functional group verification, to ensure it meets precise specifications for use in sensitive addition-cure applications. A Certificate of Analysis (COA) detailing key parameters is provided with every shipment.

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 easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep away from heat, sparks, and open flame. For long-term storage, sealing under an inert gas such as nitrogen is recommended to maintain optimal reactivity.
