74681-63-3 Usage
General Description
Methacryloxymethyltris(trimethylsiloxy)silane is a chemical compound used as a coupling agent in adhesives, sealants, and coatings. It is a colorless to pale yellow liquid with a molecular formula of C14H32O5Si4, and is soluble in organic solvents such as ethanol and acetone. METHACRYLOXYMETHYLTRIS(TRIMETHYLSILOXY)SILANE is commonly employed to enhance the adhesion and durability of materials such as glass, metals, and polymers by promoting strong interfacial bonding between dissimilar materials. Its silane functionality allows for chemical bonding to surfaces, while the methacrylate group enables polymerization and crosslinking with organic compounds. Additionally, it is often used to improve the weather resistance and water repellency of various materials, making it a valuable additive in the formulation of adhesives and sealants for outdoor applications.
Check Digit Verification of cas no
The CAS Registry Mumber 74681-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,8 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74681-63:
(7*7)+(6*4)+(5*6)+(4*8)+(3*1)+(2*6)+(1*3)=153
153 % 10 = 3
So 74681-63-3 is a valid CAS Registry Number.

METHOD FOR THE PRODUCTION OF POLYMERIZABLE SILICONES

Page/Page column 6, (2010/03/04)
Siloxy-substituted silane-containing polymerizable silicones are prepared in high purity by metering a substituted alkoxysilane into a mixture of disiloxane, acetic acid, and acid catalyst, adding acetyl chloride, separating an acidic phase from a product phase, and adding hexamethyldisilazane to the product phase, which is then distilled.
