PROSILANE™ SC-5902
Product Description
N-Octyltriethoxysilane is an organosilicon compound that features an alkyl group (octyl) attached to a silicon atom, which is further bonded to three ethoxy groups. It is a colorless, clear liquid with a characteristic odor and is used primarily as a coupling agent and surface modifier. N-Octyltriethoxysilane is known for its hydrophobic properties, promoting water repellency, and is widely applied in coatings, adhesives, and as a dispersing agent in various industrial processes. SC-5902 hydrolyzes slowly with water and is soluble in Various organic solvents. The product is high purity, Undiluted octyltriethoxysilane. After the product is dilute-ed with an appropriate solvent, it can be used to prepare Waterproof products.
