2944-70-9 Usage
General Description
Vinylmethyldiacetoxysilane is a chemical compound used predominantly as a cross-linking agent in the production of silicone rubbers and adhesives. It is a colorless liquid with a pungent odor, and is highly reactive with water, acids, and bases. When used in silicone rubber production, vinylmethyldiacetoxysilane helps to enhance the chemical and physical properties of the rubber, including its heat resistance and mechanical strength. In adhesive applications, it functions as a coupling agent that promotes adhesion between the adhesive and various substrates. However, vinylmethyldiacetoxysilane poses potential health hazards if not handled properly, including skin and eye irritation, and exposure to its vapors should be minimized.
Check Digit Verification of cas no
The CAS Registry Mumber 2944-70-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,4 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2944-70:
(6*2)+(5*9)+(4*4)+(3*4)+(2*7)+(1*0)=99
99 % 10 = 9
So 2944-70-9 is a valid CAS Registry Number.

Method of preventing discoloration of vinylacetoxysilanes
-
, (2008/06/13)
Discoloration of vinylacetoxysilanes is prevented by adding thereto 25 to 500 ppm, based on the amount of vinylacetoxysilane, of 3,5-di-tert.-butylpyrocatechol, 2,6-di-tert.-butyl-4-methylphenol, 2-mercaptobenzimidazole or a mixture thereof.
