Replacement Solvents for Nonvolatile Residue (NVR) Removal from Painted Space Hardware

Abstract

Hansen solubility parameters have been utilized to identify suitable solvents for the removal of organic contaminants and Nonvolatile Residues (NVRs). A laboratory effort was initiated to assess the feasibility of using Hansen parameters to predict the solubility behavior of multi-component systems. Specifically, we were interested in determining whether solubility parameters could be used to predict the solubility behavior of paints (a multi-component system) when NVR is removed from space hardware. Our examination revealed that although Hansen's three-dimensional model can be a useful guide for systems with single or "like type" components, it is not easily extended to multi-component paints. Caution should be used when utilizing solubility parameters as a predictive tool for applications in which NVR removal or cleaning is performed on painted space hardware.
