Product Code：SP8005
Product Name：DIMETHYLDICHLOROSILANE
Product Introduction：
Dimethyldichlorosilane is a fundamental organosilicon monomer containing two methyl groups and two hydrolyzable chlorine atoms. It undergoes hydrolysis and polycondensation to produce linear polydimethylsiloxane (PDMS) and cyclic siloxanes (D3–D10). As the primary building block of silicone chemistry, it is essential for manufacturing silicone fluids, rubbers, and resins used in sealants, lubricants, and release coatings.
