Abstract
This work deals with the study of the weathering processes due to the use of adhesive tape for the restoration of paper and for temporary exhibitions. Oxidation and depolymerization effects of industrial and handmade paper and parchment were investigated on samples in relation to the temperature, the relative humidity and the radiation exposure conditions. The experimental tests were tried out with 4x14,5 cm industrial and handmade paper and parchment samples. The following adhesive tapes were analyzed: Tesa Adhesive and Biadhesive, Eurocel Ecophan and Eurocel Biadhesive, 3M Magic 810 and 3M Biadhesive. The samples were examined by DRIFT FTIR and µ-FTIR analyses. The effects of chemical and chemical-physical processes of the adhesive-paper system were evaluated. In particular, the colour changes were evaluated by means of ΔE and ΔL values calculated according to UNI-NORMAL 43/93. The aged adhesive-paper samples had undergone some cleaning tests using different solvent mixtures with and without thickening agents. The preliminary results of the cleaning tests were compared ad discussed in order to evaluate the choice of the better methods.
