1. Used as a raw material for amino silicone oil and various organic silicon super soft finishing agents, it is condensed with organic silicon monomers such as D4 and DMC to synthesize amino silicone oil, improve the orientation of organic silicon (molecules) on the fiber, increase the affinity for the fiber, and endow the fiber with soft, smooth, hanging, anti-static, washable, wrinkle resistant and other effects. 2. Used as an additive or as a primer for coatings, inks, adhesives, and sealants such as phenolic, urea formaldehyde, furan, polyurethane, silicone, epoxy, nitrile, phenolic, acrylic, etc., to improve the adhesion, corrosion resistance, weather resistance, water boiling resistance, and scrub resistance of resin coatings, extend service life, and improve the dispersion and bonding of pigments and fillers in the resin phase. 3. Used in resin sand casting and resin grinding tools to improve the adhesion and water resistance between resin and silica sand or abrasive. Substitute polyamide bonding.
