The sample spectrum is most consistent with a resinous material containing unsaturated cyclic/alkene structures, likely a wet strength type resin, but the presence of strong bands attributable to siloxane (Si–O) and silicon–oxygen linkages introduces uncertainty. The material may be a hybrid or composite incorporating both organic resin and siloxane/polysaccharide components FTIR In-Depth Interpretation was not selected for this task, so this section shows the library-search result only and no deep AI interpretation was run.
