CAS No.
1558-33-4

Chlorosilane intermediate for silane and silicone synthesis; reacts with water to form silanols that bond to oxide surfaces.

Packed with 5L, 20L or 210L plastic/steel drum, 1000L IBC container, or according to customer’s requirement.

Product NameChloromethylmethyldichlorosilane
CAS No.1558-33-4
EINECS No.216-319-5
Structure1558-33-4
Appearance:Clear to straw liquid
Boiling Point (°C)121
Flash Point (°C)20
Applications:All chlorosilanes react with water to produce hydrogen chloride. The remaining hydroxyl group bonds to the silicon, initially forming a silol group (analogous to alcohol).
In general, this will eventually bond to a solid oxide surface or react with another chlorosilane or silol molecule. In the latter cases, the oxygen atom forms a link between two silicon atoms, analogous to the ether linkage in organic chemicals, and identical to the bonding in silicon dioxide.
Chloromethylmethyldichlorosilane are usually used as coatings for silicon and glass surfaces, and in the production of silicone (polysiloxane) polymers.
Packing:Packed with 5L, 20L or 210L plastic/steel drum, 1000L IBC container, or according to customer’s requirement.
