General Description
Methacryloxypropylbis(trimethylsiloxy)methylsilane is a chemical compound with the formula C16H36O5Si3. It is a silane coupling agent that is used as a surface modifier in various industrial applications, such as in adhesives, sealants, and coatings. METHACRYLOXYPROPYLBIS(TRIMETHYLSILOXY)METHYLSILANE contains both a methacryloxy functional group for adhesion to organic materials and trimethylsiloxy groups for adhesion to inorganic materials, making it particularly useful in improving the compatibility between organic and inorganic materials. Methacryloxypropylbis(trimethylsiloxy)methylsilane also has the potential to improve the mechanical and thermal properties of composite materials by enhancing the adhesion between the reinforcement and the polymer matrix.
Check Digit Verification of cas no
The CAS Registry Mumber 19309-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19309-90:
(7*1)+(6*9)+(5*3)+(4*0)+(3*9)+(2*9)+(1*0)=121
121 % 10 = 1
So 19309-90-1 is a valid CAS Registry Number.

METHOD OF PREPARING ACRYLOXY-FUNCTIONAL ORGANOSILICON COMPOUNDS
-
Paragraph 0072-0074, (2020/07/21)
A method of preparing an acryloxy-functional organosilicon compound is provided. The method comprises reacting (A) an initial organosilicon compound and (B) an acrylate compound in the presence of (C) a catalyst. The initial organosilicon compound (A) has one alcohol functional group (i.e., is monohydroxyl functional). The catalyst (C) has the formula M[RC(O)CHC(O)R]4, where M is a group IV transition metal and each R is an independently selected substituted or unsubstituted hydrocarbyl group. An acryloxy- functional organosilicon compound prepared by the method is also provided. The acryloxy-functional organosilicon compound is prepared in increased purity, without relying on toxic catalysts.
