Abstract: Stability of polyurethane potting compounds based on caprolactone polyol and cycloaliphatic diisocyanate in repeated autoclaving and methanol treatment was studied. While methanol treatment alone induces degradation of polyurethane and leaching of fragments, the single cycle autoclaving do not induce degradation. However, the increased cycles of autoclaving and exposure to more hydrophilic reagents like methanol enhances the degradation and leaching of low molecular weight components. There was no evidence of formation of cycloaliphatic diamine product.
