Chemical Structure


Introduction

SiSiB® PC3400 is a clear colorless, low-odor liquid. SiSiB® PC3400 may be used as an adhesion promoter (coupling agent) for organic/inorganic interfaces, as a surface modifier (e.g. regulating surface polarity) or as a crosslinking agent (moisture-curing of polymers). When used as coupling agent, it generally reduces the sensitivity of the products' mechanical and electrical properties to heat and/or moisture.
