Product Introduction

Description of vinyltrimethoxysilane:

1, Chemical Name: Vinyltrimethoxysilane
2, Formula: CH2=CHSi (OCH3)3 

Vinyltrimethoxy silane
is Colorless transparent liquid, have the taste of ester, soluble in most organic solvent, insoluble in the water if PH is 7, 
but soluble in water if PH is 3.0 to 3.5. 
Typical physical properties of vinyltrimethoxysilane:

CAS NO. 2768-02-7

Potential Applications of vinyltrimethoxysilane

(1) vinyltrimethoxysilane applies to polyethylene and copolymers with all various complex- shape and all densities or those composites 
that require the large machining tolerance and are filled in, increase their applicable temperature, high anti-pressure pyrolysis, compressive resistance, 
memory, abrasive, wear resistance and impact resistance

(2) With the function of both coupling agent and cross-linking agent, its suitable polymers such as polyethylene,polypropylene, 
unsaturated polyester, etc. vinyltrimethoxysilane can be used to improve the affinity of glass fiber,inorganic fillers and resin to 
react with vinyl, usually used in polyethylene cables and pipes of silane crosslinked polyethylene.

(3) vinyltrimethoxysilane can be used for acrylic paint copolymer,made to special paints/coatings of the external walls. 

(4) vinyltrimethoxysilane can be use as the promoter for silicone rubber, metal and textile.
Packing & storage of vinyltrimethoxysilane

1, painted Iron drum or plastic drum , net weight 190Kg each, 950kg per IBC
    packing of 1900kgs/drum,15200kgs/1x20'gp
    big packing of 950kgs/IBC,19000kgs/1x20'gp
    Customized packing is ok.
    OEM is ok.
2, Sealed well, store in a cool, dry place. Avoid light.


Silanes are important to the development of high quality materials with enhanced functionality.
