Primerless Silicone Adhesives

04/01/2000

A line of thermally conductive adhesives can be used for applications, such as bonding hybrid IC components to substrates and securing heat sinks. These one- and two-part silicones produce durable, low-stress elastomers and provide good primerless adhesion to a variety of substrates, including ceramics, epoxy laminate boards, reactive metals and filled plastics. Dow Corning`s thermally conductive adhesives generally offer long working times and produce no corrosive or harmful byproducts during cure. These platinum-catalyzed adhesives should be cured at or above 100°C. Thin sections of less than 2 mils can be cured within 15 minutes at 150°C. The adhesives are available in nominal 1-, 8-, 40- and 440-lb. containers.
