Description
Methyltriethoxysilane, an alkylalkoxysilane, is a clear, colorless liquid with an odor characteristic of alcohols. It hydrolyzes slowly in the presence of moisture to form reactive silanols, which further react to produce oligosiloxanes and then polysiloxanes. It is a versatile compound with various applications across different industries.
Uses
Used in Chemical Industry:
Methyltriethoxysilane is used as a crosslinking agent and an adhesion promoter for the production of silicone polymers or silicone resin. Its high reactivity, facilitated by nucleophilic substitution in the presence of acid or base catalysts, makes it an important component in sol-gel systems.
Used in Surface Treatment:
In the surface treatment industry, Methyltriethoxysilane is used as a filler modifier to render a wide range of surfaces and materials water repellent, such as mineral fillers, pigments, glass, and cardboard. It can be used pure or in solution, and may require pre-treatment of the substrate with water and/or a catalyst.
Used in Non-Metal Surface Treatment:
Methyltriethoxysilane is utilized in the non-metal surface treatment industry to enhance the properties of various materials, providing water repellency and improved adhesion.
Used in Polymer Preparation:
Methyltriethoxysilane is employed in the preparation of non-aqueous polymers, contributing to the development of materials with specific characteristics and applications.
Used in Semiconductor Manufacturing:
Methyltriethoxysilane finds application in the manufacture of semiconductors, where its properties are crucial for the production process and the performance of the final product.
Used in Coatings and Sealants:
It is also used in the formulation of coatings and sealants, where its ability to promote adhesion and act as a crosslinking agent enhances the performance and durability of these products.
Flammability and Explosibility
Flammable
Check Digit Verification of cas no
The CAS Registry Mumber 2031-67-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,3 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2031-67:
(6*2)+(5*0)+(4*3)+(3*1)+(2*6)+(1*7)=46
46 % 10 = 6
So 2031-67-6 is a valid CAS Registry Number.
