Product Description

Product Description

CFS-779 Methyldimethoxysilane/Dimethoxy(methyl)silane/ Z-6701 Crosslinking agent CAS No. 16881-77-9.

CFS-779 Methyldimethoxysilane or Dimethoxymethylsilane is an alkyl & alkoxy silane containing hydrogen in its molecule. It is also called methylhydrogendimethoxysilane. CFS-779 is mainly used as an important intermediate for the synthesis of functional silanes and other organosilicon compounds. It is the counterpart of Dow Corning Z-6701.

Chemical Name	Methyldimethoxysilane
Cas No.	16881-77-9
Formula	C3H10O2Si
Color	Colorless
Appearance	Clear Liquid
Purity	min 98%

Applications
CFS-779 is normally used as a raw material for the synthesis of other functional silanes. Its molecule contains a hydrolyzable dimethoxy group and an active hydrogen bond. Under hydrosilylation in the presence of Pt catalyst, different functional groups can be introduced to obtain various silane coupling agents.
CFS-779 has a suitable hydrolysis speed and can achieve deep curing. It can be used as an excellent terminating agent of polyether. Silane terminated polyether resins can be obtained with CFS-779 as the terminating agent. These silane-terminated polyether polymers are the basic materials of silane modified sealants and adhesives.
CFS-779 can be used to produce high specific surface vitreous silica gel under acidic conditions. 

Storage
CFS-779 should be stored in a cool, well-ventilated place, and avoid exposure to humidity.
CFS-779 should be stored in its original containers and used up as soon as possible after opening.
When stored in a strictly sealed and unopened container, CFS-779 has a shelf life of 12months.
