KBE-9103 is a unique silane coupling agent with a protected amine (ketimine) group, specifically Methylisobutylketoiminopropyltriethoxysilane. It is designed to improve bonding between resins (such as epoxy or phenolic resins) and inorganic substrates like metals and glass. Its latent reactivity activates in the presence of moisture, making it ideal for one-component systems in coatings and adhesives.
