CAS:85712-15-8 | Dimethoxy(methyl)octylsilane

Products Description

Dimethoxy(methyl)octylsilane has a CAS number of 85712 - 15 - 8 and an EINECS number of 288 - 374 - 3. The molecular formula is C₁₁H₂₆O₂Si, and the molecular weight is 218.408.
Dimethoxy(methyl)-n - octylsilane is a colorless to almost colorless transparent liquid with a density of about 0.8±0.1g/cm³, a boiling point of 210.9±8.0°C at 760mmHg, a flash point of 92.2±0.0°C, a vapor pressure of 0.3±0.4mmHg at 25°C, and a refractive index of 1.418.
Dimethoxy(methyl)octylsilane has a relatively active chemical property. The silicon - oxygen - carbon bond in the molecule enables it to undergo hydrolysis, polycondensation and other reactions under certain conditions. It can also react chemically with other organic substances and can be used to introduce organic groups such as octyl and methyl into other compounds.

Uses

As a release agent, the Dimethoxy(methyl)octylsilane is widely used for demoulding of plastic and rubber products. It can form a uniform isolation film on the surface of the product, making it easy for the product to be removed from the mold, improving production efficiency and product quality.

As a coating additive, it is added to the coating to improve the performance of the coating, such as improving the water resistance, weather resistance and adhesion of the coating, etc. It can reduce the surface tension of the coating surface, make the coating better wet the substrate, and improve the uniformity and integrity of the coating.

As a building hydrophobic agent, N-Octylmethyldimethoxysilane is a durable, anti - fouling building hydrophobic agent that can be used to treat the surface of building materials, such as concrete, stone, bricks and tiles, etc. It can penetrate into the material and form a hydrophobic layer on the surface, making it difficult for water to penetrate into the material, thereby improving the waterproof and anti - fouling properties of building materials and extending the service life of building materials.
