YAC-DTCS2 are formed by reaction of metallic silicon or ferrosilicon with hydrogen chloride or chlorine. YAC-DTCS2 is a colorless clear liquid.

|Colorless clear liquid
Methyl chlorosilanes have one to three methyl groups. In the case of YAC-DTCS2 dimethyldichlorosilane, dichlorodimethylsilane, two chlorine atoms are available, so that a reaction with excess water produces a linear chain of ether-like linkages between silicon atoms.
As in polyethers, these flexible linkages produce a rubbery polymer, polydimethylsiloxane (PDMS). Trimethylchlorosilane can be used to induce branching and cross-linking in PDMS molecules, while chlorotrimethylsilane serves to end backbone chains, limiting molecular weight.
YAC-DTCS2 organofunctional silanes are supplied in 200Kg steel drum.
In the unopened original container YAC-DTCS2 dimethyldichlorosilane has a shelf life of one year in a dry and cool place.
