Description

Silane, Ethenyldimethyl(Pent?Yloxy)?- CAS NO 959294-23-6 is a specialized organosilicon compound featuring a reactive vinyl group and an alkoxy substituent. This unique molecular structure makes it a valuable intermediate for introducing silicon-containing functional groups into polymer chains and surfaces. It is primarily sought after by manufacturers in the advanced materials and specialty chemical sectors for applications requiring surface modification, adhesion promotion, and the synthesis of functional polymers.

Application

• Crosslinking Agent in silicone rubber and elastomer formulations to enhance mechanical properties.
• Surface Modification Agent for inorganic fillers (e.g., silica, glass) to improve compatibility with organic polymer matrices.
• Adhesion Promoter in coatings, sealants, and adhesive systems for bonding to difficult substrates.
• Monomer/Intermediate for the synthesis of custom silicone copolymers and hybrid organic-inorganic materials.
• Coupling Agent in composite materials to strengthen the interface between fiber reinforcements and resin systems.
• Hydrophobic Coating Precursor for creating water-repellent surfaces on textiles, glass, or construction materials.
