Dimethyldimethoxysilane（Cat No.:M049353）is an organosilicon compound featuring two methyl groups and two methoxy groups bonded to a central silicon atom. This colorless, volatile liquid serves as a key intermediate in the synthesis of silicone-based materials, siloxane polymers, and surface-modifying agents. Its methoxy groups readily hydrolyze in the presence of moisture, forming silanols that can undergo condensation to create siloxane bonds. Dimethyldimethoxysilane is used in coatings, adhesives, sealants, and sol-gel processes to enhance hydrophobicity, adhesion, or durability. It requires careful handling due to its sensitivity to moisture and potential for hydrolysis.
