| Tri-functional cross-linker components commonly found in RTV silicone adhesives were quantified from fully cured samples. Samples were digested using isopropyl alcohol, potassium hydroxide and sonication. For their analysis, a GC-MS method using automated solid-phase micro-extraction was developed. Both the qualitative and quantitative evaluation of digested samples was accomplished. Interestingly, the cross-linkers were not found to be evenly distributed across the cured adhesive samples with respect to an axis perpendicular to the substrate and air interfaces. |
