Octyltriethoxysilane can used as a surface modifier to generate hydrophobicity.

Octyl triethoxylsilane is the active ingredient of high-efficiency permeable concrete silane impregnation protection agent, with good permeability, good water resistance and other advantages, the unique small molecule structure has excellent permeability, can penetrate into the base surface to form a long-term hydrophobic three-dimensional silicone network structure.

Alkoxysilanes are a family of monomeric molecules which react with water to form, typically, an alkylpolysiloxane (alkyl orthosilicate).
Formulators in the paint, ink, adhesives, water repellents, and other related industries require materials that resist peeling and penetration in spite of prolonged exposure to heat, cold, moisture, and chemical attack.
Research into these problems resulted in the development of alkoxy functional silanes for use as adhesion promoters, crosslinkers, and hydrophobes.
The ability of silane added to a coating formulation to migrate to the substrate interface and improve bonding is well known.
Silylating agent; silicone elastomer cross linking agent.

n-Octyltriethoxysilane is a monomeric medium-chain alkylfunctional silane that is used as a surface modifier to generate hydrophobicity (e.g. on concrete, glass, inorganic pigments, or mineral fillers).
Ungraded products supplied by Spectrum are indicative of a grade suitable for general industrial use or research purposes and typically are not suitable for human consumption or therapeutic use.

The n-Octyltriethoxysilane molecule contains a total of 49 bond(s) There are 17 non-H bond(s) and 13 rotatable bond(s).

n-Octyltriethoxysilane is an inorganic filler such as titanium dioxide or pigment surface treatment agent, improved and coatings, adhesives and sealants base resin affinity and wettability.
n-Octyltriethoxysilane is applied to the surface of concrete and cement and other inorganic materials, waterproofing the water and to promote the role of water vapor released from the concrete or cement.

CG-N823 can be used as a surface modifier to generate hydrophobicity(e.g. on concrete, glass, inorganic pigment, or mineral fillers)

When diluted with an appropiate solvent, it can be used in the formulation of water repellent products.
Upon proper application,the formulated product will penetrate and provide water repellency by chemically reacting with the cementitious substrate.Treated substrates are hydrophobic and retain their original appearance.

n-Octyltriethoxysilane ishigh purity, undiluted Noctyltriethoxy-silane. Whendiluted with an appropriate solvent, it can be used in the formulation of water repellent products.
Upon proper application, the formulated product will penetrate and provide water repellency by chemically reacting with the cementitious substrate.
Treated substrates are hydro-phobic and retain their original appearance.
n-Octyltriethoxysilane can also be used to improve the compatibility of mineral fillers or pigments in polyolefins or to ease their dispersion in nonpolar matrices.

n-Octyltriethoxysilane Silane is a small molecule to allow for deep penetration into the cementitious surface.
This material reacts with moisture in the air and n the substrate in the presence of an alkaline or acidic environment to produce hydroxy groups.
These hydroxy groups will bond with the substrate and tself to produce a hydrophobic treatment that inhibits water absorption into the substrate.
An alkaline environment, such as new concrete, will catalyze the reaction and speed the formation of the hydrophobic surface.

n-Octyltriethoxysilane is a kind of monofunctional silane, which can modify the surface of glass, quartz sand, metal, powder filler, etc., thus obtain good hydrophobic properties and improve the compatibility of filler with resin; Meanwhile, CG-801 can be used in tires Industry, footwear and mechanical rubber products.

Application
Aluminium alloy can be coated with n-Octyltriethoxysilane and 1H, 1H, 2H, 2H perfluorooctyl trichloro silane (PFOTS) to obtain superhydrophobicity with a high contact angle of 160-170° for vessel hulls and marine systems.
n-Octyltriethoxysilane may be used to stabilize the porosity for a colorimetric sensor for immediate color changes, which finds potential application in the detection of toxic gases.
n-Octyltriethoxysilane may also be used in the production of hybrid zeolites.
Triethoxy(octyl)silane may be used to prepare several formulations for fabricating low-cost, colorimetric sensor arrays to detect toxic gases.

N-Octyltriethoxysilane (CAS No. 2943-75-1), is an important additive for many applications.
n-Octyltriethoxysilane can be used as a surface modifier to generate hydrophobicity (e.g. on concrete, glass, inorganic pigments, or mineral fillers).
When diluted with an appropriate solvent, it can be used in the formulation of water repellent products.
Upon proper application, the formulated product will penetrate and provide water repellency by chemically reacting with the cementitious substrate.
