Artsafe™200 is a buffered, acid-free, non-yellowing and safe adhesive for mounting your most treasured giclée prints, posters, photos, fine art prints and clippings. Developed in conjunction with the British Library, Artsafe™200 is approved for use in restoration and archive work at the British Library, the Bibliothèque nationale de France and the Dutch National Archives. Simulated age testing has shown it to last 200 years without degrading. Artsafe™200 has a very low standard activation temperature (160 degrees Farenheit (70-75 degrees C) for for extra safety on fragile items and will activate with a temperature as low as 140 degrees Farenheit (60 degrees C) if required. Artsafe™200 can be reversed by careful use of Industrial Methylated Spirit (denatured alcohol).
