1. Introduction of Octadecyltrimethoxysilane

Octadecyltrimethoxysilane (CAS NO.3069-42-9) is one kind of colorless transparent liquid. Trimethoxy(octadecyl)silane is the IUPAC name of this chemical. Beside, this chemical belongs to Alkyl; Functional Materials; Si (Classes of Silicon Compounds); Silane Coupling Agents; Silane Coupling Agents (Intermediates); Si-O Compounds; Trialkoxysilanes; Alkoxy Silanes; Hydrophobing Agents. What's more, it is sensitive toward water, irreversibly degrading to a siloxane polymer.

Our Octadecyltrimethoxysilane has the high quality of 92%. It can be packaged in plastic drum or iron drum. We has the production capacity of 100 metric ton per month. We will delivery it in two days from the dongguan port. You can pay us by L/C, D/P, T/T, Westem Unoin, MoneyGram.
