Use
● n-octyltriethoxysilane is an organic silane compound, which has the following uses: 1. n-octyltriethoxysilane can be used as a building waterproofing agent and protective agent, and can form a hydrophobic layer on the surface of the substrate to effectively prevent Water seepage, sunlight, acid and alkali erosion, prolong the service life of buildings. 2. N-octyltriethoxysilane can be used as a surface treatment agent for inorganic fillers to improve the dispersion and compatibility of fillers in plastics, rubbers, and resins. 3. n-octyltriethoxysilane is used as a dispersant for pigments, so that the treated pigments have better dispersibility.
