Description

Dichlorodi-n-Propylsilane is a versatile organosilicon compound that serves as a key intermediate in the synthesis of functional silanes and silicone polymers. Its value lies in its reactive chlorosilane groups, which allow for controlled modification of surfaces and materials, imparting properties like hydrophobicity, adhesion promotion, and crosslinking. This chemical is essential for manufacturers in the silicone elastomer, sealant, and specialty coatings industries, as well as for research and development in advanced material science.

Application

• Silicone Polymer Synthesis: A fundamental monomer for creating modified polysiloxanes with n-propyl side chains, influencing flexibility and hydrophobicity.
• Surface Modification Agent: Used to treat inorganic surfaces like glass, silica, or metals to introduce hydrophobic organic layers, improving compatibility with polymer matrices.
• Adhesion Promoter Intermediate: Serves as a precursor for manufacturing silane coupling agents that enhance bonding between organic resins and inorganic substrates.
• Crosslinking Agent: Employed in the production of room-temperature vulcanizing (RTV) silicones and other crosslinked silicone networks.
• Chemical Research & Development: A valuable building block in organic and organometallic synthesis for creating novel silicon-based compounds.
• Water Repellent Formulations: Used in the development of coatings and treatments that provide water-resistant properties to textiles, stone, and construction materials.

Quality Control

Our Dichlorodi-n-Propylsilane is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee consistent quality and traceability for your production processes.

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). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and oxidizing agents.
