What is Triethoxyoctylsilane?
Triethoxyoctylsilane is colorless and transparent, and can undergo hydrolysis reactions with water.Triethoxyoctylsilane is soluble in various solvents. Triethoxyoctylsilane is a small molecular structure that can penetrate deeply into the surface of the substrate. React with air exposed to acidic or alkaline environments and moisture in the substrate to form hydroxyl groups. These hydroxyl groups will combine with the substrate and itself to form a water repellent treatment layer, thereby inhibiting the infiltration of waterCOA-Triethoxyoctylsilane into the substrate. After dilution with appropriate solvents, it can be used to prepare waterproof products. It can also improve the compatibility of mineral fillers or pigments in polyolefins, or be used to improve their dispersion in non-polar materials.

Aplicación
1. Triethoxyoctylsilane is widely used as a waterproofing agent in commercial buildings, parking lots/garages, highways, bridge structures, as well as for surface treatment of fillers. Specifically, it can be used as a building waterproofing agent and protective agent, forming a hydrophobic layer on the surface of inorganic materials such as concrete and cement, playing a waterproof role and promoting the release of water vapor from concrete or cement. Effectively prevent water seepage, sun exposure, acid and alkali erosion, and extend the service life of buildings;
2. Triethoxyoctylsilane can be used as an inorganic filler surface treatment agent to improve the dispersion and compatibility of fillers in plastics, rubber, and resins; Can be used in the tire industry, footwear industry, and mechanical rubber products.
3. Triethoxyoctylsilane can be used as a dispersant for pigments, making the treated pigments have better dispersibility.
