  • Applications

    Aminopropyltrimethoxysilane (CAS 13822-56-5) acts as a silane coupling agent that promotes adhesion between inorganic surfaces (glass, silica, cement) and organic polymers in coatings, adhesives, and composites; it is used for surface modification of glass fibers, silica fillers, and metals to improve bonding in primers, coatings, and sealants; as a reactive intermediate, it introduces amine functionality that enhances curing and crosslinking in epoxy and polyurethane systems; it is employed in coatings and inks to improve pigment dispersion and substrate wetting; it can be used to functionalize surfaces for electronics applications to enable better adhesion of subsequent coatings, encapsulants, and organic layers; in construction and plastics processing, it improves interfacial adhesion between inorganic fillers and organic matrices in polymer-modified concretes and cementitious systems.
