20-30 MATERIALE POLIMERICE UTILIZATE ÎN RESTAURAREA OPERELOR DE ARTĂ
POLYMERIC MATERIALS EMPLOYED IN
The paper presents a review of some of the most common polymeric
materials that have been employed in artwork restoration on a large scale.
Such materials have been primarily introduced in the field of cultural heritage
conservation and restoration as consolidates but proved to drastically alter their
initial properties due to natural ageing and interactions with external factors
and/or the consolidated substrate. The main alterations observed in over 20
years of use, with possible causes and mechanisms of deterioration are
outlined in this literature study.
