KBM 603

KBM 603 is N-2-(aminoethyl)-3-aminopropyltrimethoxysilane by Shin-Etsu. It is an amino functionalized silane coupling agent. The individual molecules contain two types of reactive functional groups that are amino group and alkoxy group characterized by different reactivity thus bonding with both organic and inorganic materials. It acts as a sort of intermediary which bonds organic materials to inorganic materials. It improves desirable qualities such as mechanical strength, moisture- & chemical resistance and electrical properties. KBM 603 is extensively used in adhesives to improve adhesion.
