N-Phenyl-3-Aminopropyltrimethoxysilane
N-Phenyl-3-Aminopropyltrimethoxysilane (CAS 3068-76-6) is a clear, colorless to light yellow liquid. It acts as a coupling agent, adhesion promoter, curing agent, and surface modifier. This silane compound rapidly hydrolyzes, speeding up reactions and curing times. It is widely used in plastics (like cables and fiberglass), rubber products, adhesives, coatings, inks, magnetic materials, and resin-based products such as concrete and casting resins.

| Uses |
It maximizes the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides, polybutylene terephthalate, and a host of other thermoset and thermoplastic composites. It improves adhesion between magnetic powder and organic resins and dispersion of magnetic powder inorganic resins. Also these magnetic appliances attain higher magnetic orientation and excellent magnetic properties, higher mechanical strength, good processability, excellent weathering resistance. It greatly improves wet electrical properties. With nitrile, polysulfide, epoxy, urethane, and adhesives and sealants, It improves pigment dispersion and maximizes adhesion to glass, aluminum, and steel. In glass fiber and mineral wool insulation, as a phenolics resin binder additive, It imparts moisture resistance and allows recovery after compression. In shell molding foundry applications, it strengthens the bond between the phenolics binder and foundry sand. |
