It is a disiloxane derivative that contains four methyl groups and two 2-(5-norbornen-2-yl)ethyl groups. 1,1,3,3-TETRAMETHYL-1,3-BIS[2-(5-NORBORNEN-2-YL)ETHYL]DISILOXANE is commonly used as a crosslinking agent in the production of silicone rubbers and elastomers. It provides excellent thermal stability and resistance to oxidation, making it suitable for high-temperature applications. Additionally, it is utilized in the manufacturing of adhesives, sealants, and coatings due to its strong bonding and durability properties.
Check Digit Verification of cas no
The CAS Registry Mumber 198570-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,5,7 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 198570-39:
(8*1)+(7*9)+(6*8)+(5*5)+(4*7)+(3*0)+(2*3)+(1*9)=187
187 % 10 = 7
So 198570-39-7 is a valid CAS Registry Number.

PROCESS FOR SYNTHESIZING ALKENYL DISILOXANE
-
Paragraph 0041-0045, (2021/06/22)
Described herein are methods for making alkenyl disiloxanes, comprising combining an alkenyl halosilane with a bis-hydrido terminated alkyl disiloxane and adding the mixture to water, an acidic aqueous solution, or a basic aqueous solution. The ratio of the alkenyl halosilane to the bis-hydrido terminated alkyl disiloxane is about 1:10 to about 10:1. The alkenyl halosilane and bis-hydrido terminated alkyl disiloxane are mixed at about 20 °C to about 45 °C. In an example, no organic solvent is present. The reaction product is separated and washed with saturated NaHCO3 solution (e.g., sodium bicarbonate).
