Has anyone been doing research on polishing or reducing scratches on plastics, especially translucent colored poly(methyl methacrylate) (PMMA/acrylic) ? ... Christine Haynes / Mon 25 Feb 2019 / Message: 10
Hello Christine, Bertrand Sainte-Marthe, Olivier Béringuer and I conducted a research on this topics in 2007-2009. We have worked the possibility of reducing the fine scratches and abrasions of PMMA by polishing. We have questioned the operation feasibility and its conservation safety for PMMA. We concluded that it can be done with the Micro Gloss®, a liquid abrasive composed of alumina oxide Al2O3 (less than 1 micron) commercialized by Micro Surface Finishing Products. We found that it is possible to operate either manually for the deep scratches, or with a polisher device for extended abrasions. (B. Le Namouric, B. Sainte_Marthe « Les photographies contemporaines montées sous Diasec® : traitements des dommages de surface et conservation préventive », in Conservation-Restauration des Biens Culturels, n°27 Paris, ARAAFU, 2009). We applied this method in our conservation treatments, but we did not continue the research after 2009. It would be useful to test others products. The Acrylglas Polier & Repair® from Burnus GmbH particularly seems to be of interest in the conservation field. You will find informations about filling deep scratches in Sabine Squoquart, « La conservation-restauration des photographies couleur montées par la face sur PMMA », CeROArt [Online], EGG 2 | 2012.
