Title: Techniques for measurement of structure/property relationships in coating deformation

Abstract

The deformation behavior of polymers used for precoated aluminum containers is crucial to the integrity of the container and the packaged product. Coatings have to withstand the high strains associated with the various forming processes as well as prevent permeation of product components to the coating/metal interface. Understanding the structure/property relationships of these materials will advance the development coatings capable of withstanding higher strains and exposure to more aggressive products. The focus of this investigation was to probe various existing thermal, optical and mechanical techniques for characterization of coating film deformation behavior. Model stretching experiments were performed at temperatures above and below the glass transition temperature to investigate the effects on coating deformability. Optical retardation techniques were used to determine chain orientation during the deformation process. The effect of strain rate on the thin coating films was investigated along with surface profile measurements to elucidate structure development. Finally, FT-IR and wide-angle X-ray diffraction techniques were used to study morphological and orientation behavior as a function of strain and strain rate.
