Description

Bis(Methyldichlorosilyl)Butane CAS NO 38958-24-6 is a specialized organosilicon compound featuring two reactive dichlorosilyl groups linked by a butane bridge. This structure matters for its utility as a key monomer and cross-linking agent in the synthesis of advanced silicone polymers and hybrid materials. It is primarily needed by manufacturers in the silicone elastomer, resin, and specialty adhesive industries seeking to enhance thermal stability and mechanical properties.

Application

• As a cross-linking agent in the production of high-performance silicone elastomers and rubbers.
• Key monomer for synthesizing silicone resins with tailored properties for coatings and encapsulants.
• Intermediate in the manufacture of silane coupling agents for surface modification of fillers and fibers.
• Precursor for hybrid organic-inorganic materials (ORMOSILs) used in optical and electronic applications.
• Building block for specialty adhesives and sealants requiring enhanced chemical resistance.
• Used in research and development of novel polymeric membranes and separation materials.

Quality Control

Our Bis(Methyldichlorosilyl)Butane is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets precise specification requirements. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and physical properties is provided with every shipment to guarantee traceability and compliance.

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) and reacts with strong acids/organic solvents; it must be kept under an inert atmosphere (e.g., nitrogen or argon) and isolated from incompatible substances.
