Abstract
In this study of silane adhesion promoters for coupling polyimide films to clean silicon dioxide surfaces the adhesion values obtained with three amino organo trialkoxysilanes and with several solvents for these silanes were compared. When applied from aqueous solution the silanes with primary amino groups gave higher adhesion values, as measured by a peel test, than did one having only a secondary amino group; however, when applied from organic solvents all three were effective. The highest values for all of the solvents tested were obtained with N-(2-aminoethyl)-3-aminopropyltrimethoxysilane. A fundamental discussion is presented to rationalize the differences.
