83692-44-8 Usage
General Description
The chemical "methacryloxypropylbis(trimethylsiloxy)silanolmethacryloxypropyltris(trimethylsiloxy)silane mixture" is a combination of two silane compounds - methacryloxypropylbis(trimethylsiloxy)silanol and methacryloxypropyltris(trimethylsiloxy)silane. These compounds are commonly used as adhesion promoters and surface modifiers in a variety of applications, including coatings, adhesives, sealants, and composites. They are known for their ability to improve the adhesion of organic coatings to inorganic substrates, and their presence can enhance the durability and performance of the finished product. The methacryloxypropyl groups also provide reactive sites for crosslinking or polymerization, further enhancing the chemical and mechanical properties of the materials they are used in.
Check Digit Verification of cas no
The CAS Registry Mumber 83692-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,9 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83692-44:
(7*8)+(6*3)+(5*6)+(4*9)+(3*2)+(2*4)+(1*4)=158
158 % 10 = 8
So 83692-44-8 is a valid CAS Registry Number.
