Low CTE AdhesivesOne and two component advanced epoxy systems have been developed for joining dissimilar substrates exposed to thermal/mechanically induced stresses. These dimensionally stable, low shrinkage compounds which are formulated with select fillers offer extra low coefficients of thermal expansion. Products provide the integrity of bonded joints even from high/low temperature exposure. Grades consist of electrically insulative and thermally conductive/electrically isolating systems. They are available for use in a variety of viscosities. NASA low outgassing approved systems meet ASTM E595 requirements for critical aerospace, optical, electronic and specialty OEM needs. Select products have been employed as thermal interface materials to optimize heat transfer and improve device reliability.
