87994-64-7 Usage
General Description
3-Aminopropyltris(methoxyethoxyethoxy)silane is a silane compound with the chemical formula C9H23NO4Si. It is used as a versatile coupling agent for a wide range of applications and is commonly used as a primer for metal surfaces, a crosslinking agent for polysulfide and polyurethane sealants, and an adhesion promoter for coatings and sealants. It is also used as a surface modifier for fillers and pigments in resins and plastics, and as a water scavenger in adhesives and sealants. It provides enhanced adhesion, improved chemical resistance, and increased durability to a variety of materials.
Check Digit Verification of cas no
The CAS Registry Mumber 87994-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,9 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87994-64:
(7*8)+(6*7)+(5*9)+(4*9)+(3*4)+(2*6)+(1*4)=207
207 % 10 = 7
So 87994-64-7 is a valid CAS Registry Number.

Organosilane esters having glycol ether moieties
-
, (2008/06/13)
The present invention relates to new organosilane esters which can be characterized by the formula Y-(CH2)n Si(CH3)p -Xm Z3-(m+p). In this formula, Y represents either a substituted or unsubstituted amino group, or it represents the mercapto moiety or the moiety STR1 X represents an alkoxy group with 1 to 4 carbon atoms and Z a glycol ether moiety. The index n can assume the numerical values from 1 to 3, m can be 0 or 1 and p can be 0 or 1 or 2, on the condition that m+p is equal to or less than 2. The new silanes yield very stable hydrolyzates and have good adhesion-improving properties. They are therefore particularly well suited for use in sealing compositions.
