Fig. 1: Bulk ATR-FTIR characterization fresh and 90-day cured PaDry medium.
From: Early formation and detection of lead-based products from PbO-oil paint systems

A comparison of: a) ATR-FTIR spectrum of uncured PaDry medium; b) ATR-FTIR difference spectrum between the first and last point acquired (after 90 days of curing at room temperature), c) transmission µ-FTIR spectrum of LF extracted from the cured PaDry sample thin section obtained using NNMA statistical analysis (SI of Gonzalez et al.)7. B kinetic profiles during the first 30 days of curing for: ν(OH) (3196–3554 cm−1), ν(C-H) in cis C = C-H (2991–3032 cm−1), ν(C = O) ester (1737-1776 cm−1), ν(C = O) acids, aldehydes and ketones (1690–1736 cm−1) and νs(C-O) bend of LF (758–783 cm−1).
