Organosilanes – The Original Chemical Bridge

SpecialChem / Edward M. Petrie & Edward Petrie – Mar 21, 2011

The article reviews the use of organosilanes as adhesive promoters – both as primers and as internal additives in adhesives. The unique chemical structure of the organosilane molecule is examined and its use in a wide variety of adhesive systems is discussed. The possible beneficial performance enhancements provided by silane promoters are described. Adhesion promoters were originally used to treat glass fibers and other fillers before they are incorporated into liquid resin to make composite materials, and they still have significant use in these applications. Without adhesion promoters, the interfacial resin-to-glass fiber adhesion is weak, and water can diffuse along the interface with catastrophic results on the end-properties of the composite
