Two commercial organosilicons, Hydrophase®, a monomeric dispersion, and Disboxan 450®, an oligomeric dispersion, were studied in pure form and applied on acrylic paint replicas. Their physico-chemical characteristics, coating properties, and interaction with acrylic paint replicas were evaluated by TG, DSC, FTIR, and contact angle measurements. Hydrophase® showed a higher interaction when used on the top of acrylic paint replicas than Disboxan 450®. No appreciable modification was detected after two years of natural ageing.
