Environmental Integrity of the Coating Metal Interface - Novel Non-VOC Technology

摘要

Environmental concerns demand a reduction if not total elimination of theemissions of volatile organic compounds (VOCs) from all manufacturing processes. This study seeks to identify the critical factors which will lead to the optimization of a non-VOC epoxy coating and ultimately to produce a prototype non-VOC madne primer. Our goal is to develop an ambient temperature curable epoxy coating that is fully compatible with supercritical 002 (SOF 002 ) without VOC and can meet the performance requirements at least equivalent to Mil Spec 24441. Our efforts have been focused on (1) studying the relationship between the structure of amine curing agent and its reactivity with SOF 002 and (2) identifying an amine curing agent that can reversibly release 002 at a rate fast enough to allow the formation of a coating that is uniform and void free. Our approach entails the deposition of the epoxy resin from a supercritical 002 (SOF 002) solution.
