EVALUATION OF EXISTING AND DEVELOPMENT OF NEW ANALYTICAL PROCEDURES FOR USE IN THE ANALYSIS OF FINISHES FOR GLASS FABRIC MATERIAL

摘要

Essentially all of the objectives of WADD AF33(6l6)-6289 contract "for evaluation of existing procedures and development of new analytical methods for identifying the chemical type and amount of finish present on glass cloth" are believed to have been attained.nThe strong and weak points of present methods as well as their correlation with performance are shown for vinylsilane finishes (A-172 and Garan), gamma-aminopropyltriethoxysilane finish (A-1100) and methacrylate-chromium finish (Volan A). The uniformity of loading of finish on commercially treated glass cloth has been shown. The strength of bonding has been shown by extractive procedures and by performance data.nA new simple, qualitative, rapid, colorimetric series of tests has beer developed for identifying the above finishes. New, improved quantitative procedures have also been developed for each finish.nAn electron microscopy replica technique has been developed which for the first time allows the actual surface and configuration of the finishes on glass to be seen, giving a new tool and new insights into the way finishes behave on glass.
