Triethoxy-MethoxyMethyl-silane, also known as TMMS, is a colorless liquid chemical with the formula C8H20O4Si. It is a silane coupling agent known for its ability to enhance the bonding between organic polymers and inorganic materials, particularly in the production of hybrid organic-inorganic materials. Its structure contains three ethoxy groups and one methoxymethyl group attached to a silicon atom, providing reactive sites that allow it to form strong chemical bonds with both organic and inorganic surfaces.

18379-49-2 Usage

Uses

Used in Adhesives, Coatings, and Sealants Industry:
TMMS is used as an adhesion promoter for improving the bonding between organic polymers and inorganic materials. This enhances the durability and performance of adhesives, coatings, and sealants.
Used in Silicone Rubber Production:
TMMS is used as a crosslinking agent in the production of silicone rubber, contributing to the material's strength and flexibility.
Used in Sealant Formulations:
TMMS is used as a water scavenger in sealant formulations, imparting water repellency and resistance to corrosion, thus extending the service life of the sealants.
Used in Surface Treatment of Pigments:
TMMS functions as a surface treatment agent to improve the wetting and dispersion of pigments in coatings and inks, leading to better color uniformity and performance.

Check Digit Verification of cas no

The CAS Registry Mumber 18379-49-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,7 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18379-49:
(7*1)+(6*8)+(5*3)+(4*7)+(3*9)+(2*4)+(1*9)=142
142 % 10 = 2
So 18379-49-2 is a valid CAS Registry Number.
